at around 6 mins) At the Quidditch World Cup, Amos Diggory says "Parting of the ways?" to Arthur Weasley, and they separate to go to their respective tents. This is a line from the book, only in different context. In the book, Dumbledore says this to Cornelius Fudge, when Fudge refuses to admit that Voldemort has returned. For pacing reasons, this epilogue was deleted from the movie, in favor of using it as a subplot for Harry Potter and the Order of the Phoenix (2007).
Mike Newell was not aware that Alan Rickman wore black contact lenses for the role of Snape until one day, when he was complimenting Alan on the amazing shade of his eyes, Alan leaned over and popped one of the lenses out.
The underwater scenes were shot in a huge purpose-built tank with a blue-screen background. Safety divers swam in-between takes with scuba regulators, to allow the actors to breathe without having to surface. Daniel Radcliffe alone logged around 41 hours and 38 minutes underwater during the course of filming. At one point, during training, he inadvertently signaled that he was drowning, sending the crew into a huge panic to bring him back up to surface.
(at around 6 mins) The elves Dobby and Winky were cut due to time constraints. However, if you watch carefully in the first campsite scene, right after Ginny points to something and says "Look!" you can see two House Elves riding on llamas. They go by very fast, so they're hard to see.
Costume designer Jany Temime considered Hermione's dress for the Yule Ball as the most important, comparing it to that of Cinderella. The design of the dress was changed several times, before the designers were satisfied with the results. Emma Watson was very careful not to wear it more than necessary, because she was afraid that she would wreck it.
In the books, Parvati Patil of Gryffindor has an identical twin Padma Patil of Ravenclaw, to illustrate the unpredictability of the Sorting Hat. In the films, however, Parvati (Shefali Chowdhury) and Padma (Afshan Azad) are not only both in Gryffindor but are played, surprisingly, by unrelated actresses.
The kids had around three weeks of dancing practice for the Yule-ball waltz. Daniel Radcliffe, however, appears in almost every scene of the entire film, and thus had only four days to prepare for this task. In several interviews, he has given that reason for why his dancing is shown mainly from the waist up (to avoid showing his fumbling feet). Fortunately, this wasn't a huge issue, as Harry wasn't supposed to be a brilliant dancer anyway.
During the underwater filming, Daniel Radcliffe, a couple of the cast members, and all of the underwater crew, posed for a photo, which he later sent out as a Christmas card, with Rudolph's nose and antlers Photoshopped on everyone's faces.
At least one full-scale dragon was constructed on set, which could even blow real fire. The dragon was created partially from the basilisk puppet seen in Harry Potter and the Chamber of Secrets (2002).
(at around 39 mins) Icelandic moviegoers (particularly the younger crowd) tended to crack up unexpectedly in theaters, when Rita Skeeter first introduces herself. Apparently, the audience weren't expecting the pronunciation of her last name, Skeeter, to sound so close to the Icelandic verb "skíta", which happens to be a rather crude word for defecating.
Mike Newell decided against the studio's original idea of adapting the extremely long book into two separate films to be released several months apart, figuring that he could cut enough of the book's bulky subplots to make a workable film. It was Alfonso Cuarón, the director of Harry Potter and the Prisoner of Azkaban (2004), who convinced him.
Early drafts had Ron's estranged brother Percy appearing in a key supporting role but it was written out in the final drafts. In an interview, Chris Rankin, who plays Percy, revealed that his contract of the franchise stipulates that he must appear in four films; the first three, with the option of appearing in either this movie or the next one, Harry Potter and the Order of the Phoenix (2007). Given the fact that Percy appears much longer in the latter, he opted out of the film in favor of appearing in the next one.
During the course of filming, Daniel Radcliffe matured a lot physically. In an interview, Mike Newell remarked "I've just been working on a scene which we shot in our first week, and Dan still looks like the little kid that he was in Sorcerer's Stone. Now, eleven months later, he doesn't look like that at all."
In the movie, the audience is given the impression that Beauxbatons is an all-girls academy, whereas Durmstrang is an all-boys one. In the book, however, both schools are co-ed, and in fact, in the book, the Patil twins leave Harry and Ron, to spend time with boys from Beauxbatons.
Mike Newell staged a brawl with one of the twins, both to demonstrate what he wanted for a scene between them, and also to undermine his own "authority figure" status ("They were calling me 'sir'!") The fight got so intense, that he fractured a rib in the process.
(at around 51 mins) Moody's line "I know stories about your father that would curl even your greasy hair," is actually paraphrased from a line in the book, but used in a different scenario: Rita Skeeter originally said it to Hermione about Ludo Bagman (a character omitted from the movie).
Features one of the largest underwater sets ever constructed. It has the capacity of up to 500,000 liters (132,000 gallons) of water. The largest underwater set constructed was for The Abyss (1989), which had a capacity of 26,497,882 liters (seven million gallons).
When he first signed on to direct, Mike Newell explained to David Heyman that he wanted to make a "Bollywood film". While this had him a little skeptical at first, Heyman understood what he meant. "There is no singing and dancing, but of all the films, Goblet of Fire has the most colors," Heyman said. "There's teenage romance, the glamorous Yule Ball, the theatrical Quidditch World Cup, and the spectacular Tri-wizard Tournament."
As Ron, Harry, and Hermione are talking in the great hall, before George and Fred attempt to enter their names in the Goblet, Hermione is reading a book. We can't see the title, but the cover features the harlequin pattern of the UK editions of the Harry Potter novels.
(at around 1h 45 mins) In the scene with Dumbledore, Harry, and the Pensieve, pay close attention to the glass cabinet Dumbledore approaches while explaining the Pensieve. In the top left corner is a 3D model of what becomes an important symbol in the final novel, Harry Potter and the Deathly Hallows.
(at around 1h 5 mins) The character Nigel, who appears in this film, and Harry Potter and the Order of the Phoenix (2007), does not appear in the books at all. Given his short stature, and apparent idolizing of Harry, it seems likely that he is meant to act as a substitute for Colin Creevey (from Harry Potter and the Chamber of Secrets (2002)) and his brother Dennis (who is introduced in the Goblet of Fire book).
In the book, Voldemort is described as having red eyes with slits for pupils. The filmmakers ultimately decided not to give Voldemort red eyes, because they felt that one wouldn't be able to read the emotion in the eyes if they were modified, and therefore the character wouldn't be scary enough. If you look closely during his final reformation stages, he opens his eyes just before it's fully completed, and very briefly his pupils are indeed like slits rather than human pupils.
The rock band at the Yule Ball is comprised mostly of members of Pulp and Radiohead. In the run-up to the movie, a Canadian folk group called the Wyrd Sisters filed a forty million dollar lawsuit against Warner Brothers, the North American distributor of the film, Jarvis Cocker from Pulp, and Jonny Greenwood and Phil Selway, of Radiohead for the use of their group's name. In the book, the band is called the "Weird Sisters", after the witches in William Shakespeare's "Macbeth", but was reportedly renamed the "Wyrd Sisters" for this film. Before the movie was released, however, Warner Brothers removed all references to either name for the band. (In a deleted scene included on the DVD, Professor Flitwick introduces the band as "The band that needs no introduction.") Nevertheless, the Wyrd Sisters moved for an injunction in a Canadian court to prevent distribution of the film in Canada. This motion was dismissed by an Ontario judge.
Mike Newell originally decided not to have the make-up on Ralph Fiennes to give a more scary Voldemort. But he changed his mind after seeing a minimal make-up design by Nick Dudman. To complement the make-up, Fiennes shaved his head, as well as his armpits.
The tune you hear the teens sing to the school song, "Hogwarts, Hogwarts, Hoggy Warty Hogwarts" is traditionally sung to any tune the singer happens to like, but for the sake of clarity this has been changed to a chain-song with a fixed melody in the film. The song performed that way in its entirety can be heard in a deleted scene on most home video releases, lyrics first appeared in the first novel, "Harry Potter and the Philosopher's/Sorcerer's Stone".
Mike Newell wanted the Dark Mark to "bubble up" out of the skin of Voldemort's followers. The makeup department achieved the effect by applying variations of a silicone skull-and-snake to each actor's arm, gradually making the mark appear more "raised and angry looking". Digital effects were then used to create the snake's movement.
This is the first Harry Potter film to receive a "PG-13" rating or its international equivalent (for sequences of fantasy violence and frightening images). The preceding films having been rated "PG" or one of its international equivalents.
(at around 25 mins) The creature Mad-Eye Moody torments in his "dark arts" class (a spider in the book and the original script) is virtually identical to a real animal: the tailless whip-scorpion. Tailless whip-scorpions, of which some 130 species are known, fall in their own taxonomic order 'Amblypygi' under Class 'Arachnida', and are neither scorpions or spiders. Though Moody avers that this one is deadly, real Amblypygids are quite harmless (though almost as big).
Only one of the actresses portraying French characters speak with a natural French accent (Clémence Poésy), Clemence Poesy was born and raised in France, and the actress who plays Madame Maxine is from England.
Daniel Radcliffe, arguably, looks more like the book version of Harry Potter in this film, as his hair in the film is the longest and messiest in the entire franchise. In the book series, Harry Potter is said to have long and messy hair.
This is the first movie to not show the Dursleys. They were featured in the book in the very beginning, where they are visited by the Weasley family, who come to pick up Harry for the Quidditch World Cup. This was omitted from the movie, because the actors portraying the Dursleys demanded more money, so they were cut, and this is why Harry is shown spending the night at the Weasley's just before the Quidditch World Cup.
Although it is not explained in the movie, Fleur Delacour is described as part Veela in the books. Veelas in the Potterverse are magical nymph-like beings that have the ability to charm men. Fleur actually has a strand of her Veela grandmother's hair as the core of her wand.
A digital "spot removing" technique (which had previously been used for such television shows as Desperate Housewives (2004)) was applied in post-production to clear up some of the more severe teen skin problems, since make-up tested poorly for close-up shots in particular.
(at around 7 mins) In the movie, the Weasleys have really high seats at the Quidditch World Cup. The Malfoys make fun of them for being so high up in the "nosebleed section." In the book, however, the Weasleys have just as good as or even better seats than the Malfoys. The tickets were given to Arthur Weasley by Ludo Bagman at the Ministry of Magic, whose character is cut out of this movie due to time. Ludo's character is also a degenerate gambler, and throughout the book, tries to help Harry cheat in the Triwizard tournament; Harry refuses his help.
(at around 1h 35 mins) After the second task, as Dumbledore magnifies his voice, his wand can be seen with a white band on it that bears the mark of a straight line atop a few lines in a criss cross pattern all atop a circle, which will all be important plot elements in future installments.
In the novel, Hermione uses the Sleekeazy's Hair Potion, a hair care potion, to straighten her hair for Yule Ball. J.K. Rowling would later reveal on Pottermore, as part of the Potter family background, that this potion was invented by Fleamont Potter, paternal grandfather of the title character, Harry Potter.
The inscriptions on the Riddle's family tombstone had to be digitally changed at the last minute after fans of the books, having seen promotion stills released from the graveyard scene, pointed out that none of the Riddle names on the tombstone referred to Voldemort (a.k.a. Tom Marvolo Riddle), as the filmmakers erroneously thought, but to his dad, Tom Riddle (Sr.), his grandfather, Thomas Riddle, and his grandmother, Mary Riddle.
The ice sculptures at the Yule Ball were made of resin (as real ice obviously would melt). Though the resin was clear, it appeared pink beneath the white stage lighting. To solve this issue, blue lighting gels were used to turn it icy blue.
(at around 1h 50 mins) When Harry is entering the maze, Mad Eye signals him that he should turn to his left. There is a wide belief that if one keeps turning left in a maze, he or she shall find his or her way out.
The name of "Durmstrang Institute" appears to be paying homage to the "Sturm und Drang" (translation: Storm and Stress) movement in German literature. The movement, which flourished from around 1770 to 1785, was distinguished by its theme of youthful genius in rebellion against accepted standards, much like Harry and his feelings about the wizarding world's attitude toward the Dark Lord.
The walls of the Great Hall were covered in highly-reflective silver Lurex fabric for the Yule Ball sequence. Originally paint was going to be used, however, it was too flat, and did not have the desired effect. The same material was also used to create the curtains.
In the first draft of the script, a subplot featuring the Weasley twins and Ludo Bagman, the head of the Ministry's sports department, was featured prominently. In fact, it was reported that Martin Landham was cast as Bagman. In the subsequent drafts, the subplot was dropped, and the character of Ludo Bagman makes no credited appearance in the movie.
Rumors on the Internet of a Scottish actor being cast as Viktor Krum were halted, when it was announced that, as originally planned by the producers, a Bulgarian would in fact play the part. Perhaps these rumors arose because the Bulgarian was discovered in England, and not in Sofia, where there was a casting call for the part of the International Quidditch Champion. Stanislav Yanevski, a Bulgarian student living in London, had been cast in the role.
In the extended version of the movie, that airs on ABC Family, when Harry is questioned by Snape about stealing from his potion/ingredient closet after Snape says "Boomslang Skin?" "Lacewing Flies?" Snape shuts the door on Harry. The line "You and your little friends are brewing Polyjuice Potion, and believe me, I'm going to find out why." is omitted from this version, but appears on the DVD.
In the novel, Hermione Granger wears a periwinkle blue dress to the Yule Ball. In the film, she wears a pink dress instead, as it was felt that a blue dress would not have stood out well enough against the blue background chosen for the Yule Ball sequence. Some fans disliked the change, as they felt the pink dress color did not suit the character. Also, the costumer designer felt that blue didn't suit Emma Watson.
Scottish band Franz Ferdinand was the first choice to perform as the Weird Sisters, but they declined. Due to the similarities in name, the Canadian band Wyrd Sisters attempted to stop the film's release in Canada, by filing a lawsuit, but were unsuccessful.
Currently, the DVD holds the Guinness World Record for being the fastest selling DVD of all time. The achievement was added to the 2007 book edition of The Guinness World Records, which includes a picture of the award being presented to Daniel Radcliffe on the set of Harry Potter and the Order of the Phoenix (2007) at Leavesden Film Studios in April 2006.
First film in the series not to be dubbed into Icelandic (and other languages alike), where dubbing for theatrical release is limited to projects primarily aimed at children. In fact, even with different ratings of the following films, dubbing did not resume for some of those languages (like Icelandic).
(at around 7 mins) When Harry passes inside of the Weasley's cabin (during the Quidditch's Mundial), he discovers that it's bigger inside than outside. The same idea was shown in Doctor Who (1963) with the TARDIS. David Tennant, who plays Barty Crouch, Jr., was the tenth Doctor in Doctor Who (2005).
(at around 1h 17 mins) Many fans and critics mocked Hermione's "Cinderella" entrance to the Yule Ball in comparison to the original novel, as it was felt that Emma Watson was simply too cute for the intended "butterfly effect" from the novel to be effective, even considering it unintentionally silly. Even Daniel Radcliffe mocked the film's handling of the scene, saying his co-star Watson, who is known for being a style and fashion nut, looked the same as before.
The dragon faced by Harry is no dragon at all. As it does not have front legs, it is clearly a wyvern. Although the two are often confused, wyverns have two back legs and wings coming out of where their front legs would be, and dragons have two sets of legs plus wings coming out of their back. Wyverns generally are considered lesser cousins of the dragons, and are often unable to breathe fire. Another cousin of the dragon is the drakon, appearing identical to dragons, only lacking wings. These were originally considered for the book, but were eventually replaced with a more familiar dominating mythical creature.
Chris Columbus, the director of the first two Harry Potter films, was amazed how beautifully Daniel Radcliffe, Emma Watson, and Rupert Grint matured over the franchise, compared to some child actors, who start out adorable, and then either lose that, or become bad actors as they grow older.
Caio Cesar, a prominent Brazilian voice actor, who dubbed Daniel Radcliffe as Harry Potter, and in other films, was also a military cop, and died at the age of 27 in 2015, after being shot in his neck, at the Complexo do Alemão slums, in Rio de Janeiro.
The members of the "Weird Sisters" were played by: Jarvis Cocker (of the band Pulp) as "Myron Wagtail" (vocals), Jonny Greenwood (of Radiohead) as "Kirley McCormick" (lead guitar), Jason Buckle (of All Seeing I) as "Heathcote Barbary" (rhythm guitar), Steve Mackey (also of Pulp) as "Donaghan Tremlett" (bass), Steve Claydon (of Add N to (X)) as "Gideon Crumb" (keyboards and bagpipes), and Phil Selway (also of Radiohead) as "Orsino Thruston" (drums).
When Chris Columbus scripted Young Sherlock Holmes (1985), Watson believed Holmes obsessed over a case, even at Christmas, because unlike other boys his age, he had no family to which to go home, like Harry Potter or Kevin McCallister. Columbus has ties to both the Harry Potter and Home Alone franchises.
The trivia items below may give away important plot points.
Robert Pattinson has stated that he would much rather play Cedric Diggory again, despite the character being killed off in this film, than play Edward Cullen in the Twilight Saga, the role he is perhaps best known for.
Ralph Fiennes was not wearing any make up to cover his nose. In order to make the character scarier, film editors digitally removed it. Also, the "red, snake-like eyes" the novel describes were not added, due to the actor's thought that the expression in his eyes would provide a better idea of Lord Voldemort's insanity and malignity.
The occasional tongue flick done by the character of Barty Crouch, Jr. was, in fact, not in the book at all, and was improvised, on the spot, by David Tennant. Brendan Gleeson then added the quirk to a few of his scenes as a hint to the Crouch/Moody substitution. In fact, after the second task, when "Moody" and Crouch, Sr. are talking, Crouch's reaction to seeing Moody do this, could suggest that he might know something about Moody's true identity.
at around 2h) Voldemort identifies four of his Death Eaters by name: MacNair, Crabbe, Goyle, and Lucius Malfoy. Lucius Malfoy is the father of Draco Malfoy. The Crabbe and Goyle that he names are the fathers of Draco's friends, who are also usually addressed by their last names. The last one, MacNair, is identified in the book as the would-be executioner of Buckbeak in Harry Potter and the Prisoner of Azkaban (2004).
There were four characters that had big parts in the book, but were completely written out of the film. These characters were: Ludo Bagman, head of the Ministry of Magic's sports department and tournament judge; Winky: the former Crouch house elf that was believed to have cast the dark mark at the Qudditch World Cup; Bertha Jorkins: a woman who was tortured by Voldemort and Wormtail to tell them about the Tournament being held at Hogwarts; and Bellatrix Lestrange, one of Voldemort's fiercest supporters, as seen in Dumbledore's Pensieve memory. Lestrange would finally be introduced in the next film, Harry Potter and the Order of the Phoenix (2007).
at around 1h 45 mins) In the film it is stated that Barty Crouch, Jr. performed the Cruciatus Curse (torture curse) on Frank and Alice Longbottom, however in Harry Potter and the Order of the Phoenix (2007), Neville Longbottom states that his parents were tortured by Bellatrix Lestrange. In fact, both are correct. The books state that the Longbottoms were tortured by a group of Death Eaters, including Barty Crouch, Jr. and Bellatrix and Rodolphus Lestrange. Dumbledore adds that, while the Lestranges were sadistic by nature, Crouch Jr. was very young, and easily swayed, and probably coaxed into doing it by the others.
The writing out of Dobby in this film (Harry Potter and the Order of the Phoenix (2007)) resulted in a slightly larger role for Neville Longbottom. In this film, it is Neville, rather than Dobby, who gives Harry the gillyweed for the second task, and we later learn that this idea was given to him by Barty Crouch, Jr./Professor Moody. In the book, Crouch/Moody explains that his first approach was in fact to give Neville the book where gillyweed could be found, but Harry didn't ask Neville, because he wasn't supposed to ask for help, so he only told Ron and Hermione what he had to do. So Moody arranged for Dobby to overhear him talking about it. This removal creates a rather uncharacteristic byproduct - Neville, who is supposed to be terrified of Professor Snape, would have had to steal the Gillyweed from Snape's store.
at around 1h 45 mins) When Harry was talking to Dumbledore in his office, after seeing the flashback of Barty Crouch, Jr., you can see the Deathly Hallows symbol when Dumbledore looks into the glass cabinet.
at around 37 mins) You can clearly see The Elder Wand for at least fifteen seconds, when Dumbledore takes his memory to the Pensieve. The Elder Wand is the vital element in the last installment, Harry Potter and the Deathly Hallows: Part 2 (2011).
at around 23 mins) It could be implied Karkaroff was the person who put Harry's name in the Goblet of Fire, as he is seen entering the Great Hall where the goblet is, before giving a very shifty looking appearance, before closing the door, just before Moody's lesson about the Unforgivable Curses. Plus, Karkaroff gives another shifty look when the goblet is about to spit out Harry's name. This suggests that even though Harry claimed Moody (who is really Barty Crouch, Jr. in disguise) put his name in. Karkaroff was either aiding Crouch, Jr. to bring back Voldermort, or more likely, was placed under the Imperius Curse by Crouch, Jr.
When Barty Crouch Jr. is in disguise as Mad Eye Moody his tick with his tongue is on the opposite side as to Barty Jr. David Tennant (Barty) displays his tick at the right corner of his mouth whereas Brendan Gleeson (Moody but in disguise) displays it on the left side of his mouth.
When the twins are denied entering their names in the Goblet of Fire, they are thrown out and grow beards. When they start wrestling, Fred tells George, "Get off or I'll tear your ears off." In Part one of the Deathly Hallows, George gets his ear cursed off by Snape.
