Sigourney Weaver made the behind-the-back half-court basketball shot successfully after 3 weeks of basketball practice, tutored by a basketball coach. Her conversion rate during this time was 1 of overt 6 shots. When the day came to shoot the scene, director Jean-Pierre Jeunet wanted to have the ball dropped in from above, rather than wait for Weaver to sink the shot herself, which "would probably take about 200 takes." Weaver insisted she could get the shot in herself, and was allowed to do. Though it is commonly said that she sunk the basket on her first attempt, it actually took her endless takes to complete the stunt. Jean-Pierre Juenet gave her one last try to sink the basket before they would give up and use CGI or a second ball. The very next take, Sigourney Weaver successfully managed the trick. Ron Perlman was completely stunned (and thoroughly impressed), and turned directly at the camera and broke character, saying; "Oh my God!" The editors looked at the shot, and decided there was "enough room to get the scissors in." Weaver was excited about making the shot, but Jeunet was concerned audiences would believe the shot to be faked due to the ball leaving the frame. Upon Weaver's insistence, he kept the shot as it was. Weaver described the miracle shot as "one of the best moments in her life", after her wedding day, and the birth of her daughter.
Actor Ron Perlman nearly drowned while filming the underwater sequence. At one point, when trying to surface, he hit his head on a sprinkler in the ceiling, knocking him out cold. He was rescued by nearby film crew members.
When pre-production was underway, the original 'Alien Queen' could not be located and the molds that were used to build the original were damaged beyond usefulness. Fortunately, the original life-size puppet was located... in the personal collection of an avid Alien (1979) fan.
Jean-Pierre Jeunet wanted to have a scene where a mosquito stings Ripley, then vanishes into smoke because of her acid blood. Eventually, he dropped the idea after the SFX team told him how much it would cost.
The studio wanted to cut the scene preceding Ripley's encounter with the alien queen because of its rather sexual nature. They decided to keep it when Sigourney Weaver threatened to not promote the film if the scene was cut.
Joss Whedon has commented on his dissatisfaction with the movie. Fans had speculated that the finished article deviated from his original script in some fatal manner, however he put such rumors to rest. His dialogue, action and plot were essentially intact. However he had written with a playful, tongue-in-cheek tone, which didn't work when the director decided to "play it straight." Eventually the Betty and her crew became the prototypes for Whedon's Firefly (2002), which captured the tone he had aimed for in this movie.
The underwater sequence marked the first time that Winona Ryder had gone underwater since a near-drowning incident that happened to her when she was 12 years old. The actress suffered a complete anxiety attack on the first day of filming in the underwater set.
Ron Perlman did most of his own stunts, particularly the scene where he hangs upside-down off a ladder by his legs whilst firing two guns at an alien. The next day, when he went to take a shower, he discovered he had severely lacerated the backs of his knees in doing so.
Director Jean-Pierre Jeunet spoke almost no English at the time of shooting and had translators on set at all times. By the time the Special Edition DVD was released in 2003, he had learned enough English to record a director's commentary.
In order to heighten contrasts, cinematographer Darius Khondji added silver to the printing process. This had the result of making the dark colors richer and giving everything else a metallic tinge. He also used an electric blue tint for the underwater sequence.
When Johner says to Ripley; "So I hear you, like, ran into these things before. What did you do?", Ripley replies, "I died." Left on the cutting room floor was Johner's retort; "That's not exactly what I was hoping to hear."
Winona Ryder agreed to do this film even before reading the script. She stated that she "didn't care if she died in the first scene", she'd do it. Ryder claimed that then she could boast about being in an "Alien" movie to her younger brothers.
In her initial scenes with the Newborn, Sigourney Weaver makes a point of not looking in its eyes. This was a lesson learned from when she made Gorillas in the Mist (1988) in not making initial eye contact with a potentially dangerous animal.
The $50-60 million budget was significantly lower than the director and writers originally imagined. Therefore, sets were toned down in scale and a more claustrophobic shooting approach with a lot of close-ups to characters' faces was taken.
In the scene where Dominique Pinon appears out of an elevator, his line originally was "Who were you expecting? The Easter Bunny?" However, Pinon kept saying "Eastern Bunny", to which his fellow actors would break out in laughter. The crew printed T-shirts with the line. Interestingly enough, the new line; "Who were you expecting, Santa Claus?" had also been used in Jean-Pierre Jeunet's previous movie, The City of Lost Children (1995), where it was directed at Ron Perlman as well.
Joss Whedon was unhappy with everything about the film. He later commented in 2005: "It wasn't a question of doing everything differently, although they changed the ending; it was mostly a matter of doing everything wrong. They said the lines but they said them all wrong. And they cast it wrong. And they designed it wrong. And they scored it wrong. They did everything wrong they could possibly do. That's actually a fascinating lesson in filmmaking. Because everything they did reflects back to the script or looks like something from it. And people assume that if I hated it then they'd changed the script...but it wasn't so much they changed it, they executed it in such a ghastly fashion they rendered it unwatchable."
Joss Whedon originally scripted the Newborn creature as a deadly four-legged, eyeless, bone-white creature with red veins running along the sides of its head. It had an inner jaw, similar to the all the other aliens. It also had a pair of pincers on the sides of his head. These pincers were used to hold its prey still as it drained the prey of blood with its inner jaw. The creature was also larger, nearly the size of the queen alien. In later script revisions, the creature was changed into a "more believable" hybrid of human and alien.
The actors were subjected to about 15 underwater training sessions in swimming pools around the Los Angeles area before arriving at the underwater set where they underwent a further 2 weeks of training before anything was shot. Sigourney Weaver missed most of this because she had been appearing in a play on Broadway just prior to filming.
Originally, the fourth alien movie was to be a rendition of the popular comic Aliens Vs. Predator, which combined the Alien creatures with Predator (1987) since 1991. It took another 7 years before AVP: Alien vs. Predator (2004) saw the light.
Jean-Pierre Jeunet wanted to shoot additional action scenes using a fully digital Newborn creature. He wanted Ripley to be chased by the Newborn in the escape from the Betty scene, but could not realize it due to budget constraints. In the final film, a full-size Newborn creature can be seen in only one scene and almost all of the scenes involving the creature are animatronic.
One of the concept designs of the Newborn involved the creature sporting a likeness of Sigourney Weaver's face. This was abandoned as it bore too much of a similarity to Sil, the alien creature in Species (1995).
The script and promotional material reveal that the orbit of Auriga was beyond Pluto. The project was not approved by the Congress, possibly due to its hazardous nature. According to the script the USS military cultivated vast quantities of cannabis to fund the cloning program since they could not rely on the goverment for an official subsidization. The goverment could not observe the military beyond the boundaries of the solar system. Although this subplot was dropped from the film there are still hints of this backstory when Elgyn remarks that the operation was not authorized by the Congress and that Auriga is located in unregulated space. This also explains the assertion of Call that Dr Wren is conducting illegal experiments.
The Newborn's skull was made of plaster so it could be sucked out of the window into space. Cast only at 1/8-1/4" thick, it was scored into various pieces. Each piece was individually attached to a wire, so when struck against the window and cracked, each fragment could be pulled out one-by-one.
Joss Whedon went through five different versions of the final battle with the "Newborn" creature, the first four versions of which all took place on Earth in such settings as a hospital maternity ward, a giant junkyard, a snowy forest and cliffside, and a desert.
Nigel Phelps based the design of the spaceship "Betty" on a jackhammer. The "Auriga" was originally to be a vertical structure, but he abandoned this idea once he realized the difficulty of capturing the scope of such a ship design on film.
The Auriga interactive computer is named "Father." In the original Alien (1979), the computer's name was "Mother." There are even compatible scenes where people yell at Mother or Father for not responding to them.
Ripley's outfit was going to be a different one than the dark red uniform she is wearing for the most of the film. After Sigourney Weaver saw Kim Flowers (Hillard) on the set, she wanted to wear the same costume. Hillard can be seen in the exact same outfit in the underwater scene.
The film's model miniatures were shot at a former Howard Hughes aircraft plant in Los Angeles. Visual effects supervisor Erik Henry and visual effects director of photography Rick Fichter used an advanced motion control camera system that required constant vigilance and re-alignment as the area was prone to small earthquakes and tremors.
For the luckless human victims which the renegades find, as if already having had the aliens burst out of their stomachs wasn't enough, the crew devised costumes which had stomach entrails stitched onto the outside. This was directly inspired by a T-shirt that was popular around the time of the release of Alien (1979) in which an alien fetus (and a lot of blood) was attached to the front.
The gaps between the four Alien films steadily decreased. There was seven years between the release of Alien (1979) and Aliens (1986), six between Aliens and Alien 3 (1992), and five between Alien³ and Alien: Resurrection (1997).
The scene with Ripley waking up gradually was not in the script. It was an addition by the director in order to symbolize the creation of the clone as a larva which transforms into a butterfly and tears up the cocoon.
All four "Alien" movies featuring Sigourney Weaver have a scene in which Ripley is seen dining with the ship's native inhabitants, and a sexual comment is made by someone at the table (in this movie, Ripley is prompted to say "fork" and says "f*ck" instead).
The first draft of the script contained an action sequence which took place in a garden contained within the spaceship "Auriga," with Ripley driving an electrically-powered jeep to avoid aliens attacking from all sides. This was to take place after the scene in the chapel but before the sequence where the Newborn is introduced. The sequence was cut due largely to budget constraints.
The tube where the clone of Ripley is created was scripted as a regular bed like case, much like the cryo tubes in which the hosts of the aliens are carried by the Betty crew. It was an artistic choice to render the glass chamber vertical shaped.
Paul W.S. Anderson was in talks to direct but was unable to take part due to scheduling conflicts. Anderson would still get his chance to direct an outer space opus the following year with Event Horizon (1997). And of course he would visit the Alien franchise several years later with AVP: Alien vs. Predator (2004).
Appx. 1h 25 mins, Leland Orser's character is called Larry Purvis in the credits. In the original script, he was supposed to have his last name on his jumpsuit, and Christie calls him by that name. This scene was changed in the final cut, and the only person who refers to him as Purvis is Call, when they get ready to put him in the Betty's freezing chamber towards the end of the film.
The USM Auriga was originally designed by artist Nigel Phelps and resembled a medical instrument. This design proved to be too vertical for the film's opening shot, in which the camera pans out to show the ship, and did not appear satisfactory in the film's 2.35:1 aspect ratio. Three days before the design had to be finalized, Jean-Pierre Jeunet rejected it. Phelps, production illustrator Jim Martin, and concept artist Sylvain Despretz were tasked to redesign the ship. Jeunet felt Martin's design was too much like a space station, while he accepted Despretz's design due to its streamlined and horizontal appearance.
The film had originally ended with the Betty arriving on Earth, landing in the ruins of Paris and Ripley and Call sitting down and trying to decide what they are going to do and Ripley doesn't know what to do, because she is a stranger to Earth.
In the film, Call is revealed to be a "Auton". In the long-running BBC science fiction series "Doctor Who", the Jon Pertwee, Christopher Eccleston and Matt Smith incarnations of the title protagonist The Doctor fought living plastic dummies called The Autons. John Hurt, who played Kane in the original film, played The War Doctor in the series' 50th anniversary special The Day of the Doctor (2013); and Paul McGann, who played Golic in "Alien 3", played The 8th Doctor in the 1996 TV movie, and returned in the mini episode Night of The Doctor (2013), which saw The 8th Doctor regenerate into The War Doctor.
At around 55 mins) When Ripley discovers all of the other "failed" alien/hybrid clones of herself, she finds one still alive who begs Ripley to mercy-kill her, which Ripley does, with a flame thrower. This idea was recycled from a deleted scene from Alien (1979), wherein Ripley finds Dallas, and he asks her to mercy-kill him, which she does with a flamethrower in a similar manner.
At appx. 1h 35 mins, to achieve the shot where the camera travels inside Leland Orser to see the alien fetus about to be birthed, Orser had a camera down his throat and then pulled out. This was then reversed.
General Perez (Dan Hedaya) was initially scripted to die in a decompression scene, with him being sucked through a small hole in a window. However, Jean-Pierre Jeunet thought this was a much too spectacular death for such a minor character, so this idea was instead used for the death of the Newborn. Perez's eventual death scene (with him being bitten in the back of his head, and observing a piece of his own brain) was not approved by the studio, but kept in the movie after test audiences responded quite favorably.
The film originally ended with the Betty landing on Earth and Ripley and Call viewing the ruins of Paris. The scene was shot but the idea was abandoned for the theatrical release. When Jean-Pierre Jeunet was invited to create a Special Edition of the movie, the idea was revived and the scene's visual effects finished.
The first draft of the script included a different climactic fight between Ripley, Call, and the Newborn. Originally, after the Betty crash-landed on Earth, Ripley and Call were to battle the Newborn on a snowy mountain, using a "Harvester", a reaper-like farm machine which they had found during the garden chase sequence (which was also cut from the film due to budget limits).
The Special Edition includes a scene which eliminates controversy about the extent of damages caused by the collision course of Auriga. Call re-calibrates the velocity and the coordinates of Auriga so the space station will crash onto an uninhabited quadrant of Earth. Not only is this consistent with Call's intentions of saving mankind and not inflict any human casualties, but this also ensures that after the impact, the repercussions of the wave will not cause any harm.
Director Jean-Pierre Jeunet was given license to change the script as much as he wanted, and the final film is substantially different than Joss Whedon's original script. Characters and situations were merged, simplified or removed, and the overall tone was made more fanciful and less realistic. Things changed or removed include: An Asian assassin called St. Just (pronounced "San-Jhoost") was original part of the Betty's crew. Johner was described as being more of a crazy, psychopathic character. After the underwater sequence, the characters were then forced to climb up a 50 story lift-shaft, with aliens attacking them. After the Chapel scene, there was an action sequence in the ship's "farm", including a moment were the crew discovers the army has been growing cannabis. The Newborn alien was originally extremely deadly, the size of a Queen alien, and there was little emotional connection between it and Ripley. The final action sequence took place on Earth, ending with the surviving characters (including Ripley) deciding to stick together.
The film ends with the Newborn being sucked out of a tiny hole in the spaceship's hull, an idea that was considered for Alien (1979) but abandoned because of budgetary constraints. It was also proposed for dispatching a minor character in one of the drafts of Alien 3 (1992).
In Call's back-story: When the android industry declined. The second generation androids or Autons (androids designed by androids) were developed, after an attempt to revitalize the android industry. The Autons rebel and only a few androids escaped the massacre and Call was created as a Auton secret agent and joined the Betty crew as a mechanic, so she could destroy the cloned xenomorphs aboard the Auriga.
The final chestburster was not intended to die during the climactic gunfire. According to the script the leads would chase the chestburster inside the Betty not wanting to risk damaging the hull with bullets. Call would stab it with her stileto.
In the scene which Ripley kills a Xenomorph by shooting it in the head. Call argues with the Betty crew that they cannot trust Ripley, which Christie answers "I don't trust anyone.". This is a nod to a scene in the original Alien (1979), which Ripley has a argument with Dallas about Ash bringing the facehugger back to Earth. Ripley tells Dallas that she doesn't trust Ash and Dallas replies by telling he doesn't trust anyone.
