In an interview, director Paul W.S. Anderson said that Arnold Schwarzenegger offered to reprise his role as Dutch Schaeffer (from Predator (1987)) at the end of this movie as a cameo, but only if he lost the election for California Governor. Schwarzenegger famously won the election, so he was unavailable to appear.
The Antarctic setting on Bouvet Island is based on the unexplained "Vela Incident" of September 22, 1979, where a satellite recorded a flash of light near the island. It was first speculated to have been a man made nuclear explosion, or a natural event, such as a meteor strike, but this has never been resolved.
When Lex asks Sebastian how to say "scared shitless" in Italian, he replies "Non vedo l'ora di uscire da questa piramide con te, perché mi sto cagando addosso." Translated, this literally means "I can't wait to get out of this pyramid with you, because I'm shitting myself."
Was rumored to be in development ever since a skull from the title characters in the Alien film series appeared in the spaceship trophy room in Predator 2 (1990) (even though that was only meant as a nod to the popular Alien vs Predator comic book series).
While this film languished in "development hell" for years, 20th Century Fox considered producing a fifth film in the "Alien" franchise instead. James Cameron, who wrote and directed Aliens (1986), had written a script and even approached Sigourney Weaver to star and Ridley Scott to direct, both of whom expressed interest. When the studio decided to use the Alien and Predator crossover story instead, Cameron, Weaver, and Scott all distanced themselves from the project, and later declared they would never work on either franchise again. Several years later, Ridley Scott ended up reworking his pitch into his Alien prequel Prometheus (2012).
The character played by Lance Henriksen, Charles Bishop Weyland, is a co-founder of the Weyland Yutani Corporation. This is "the company" referred to in the "Alien" movies. In the continuity of the AvP movies, he is meant to be the "ancestor" of the Bishop Android from Aliens (1986) and Alien³ (1992), who were also played by Henriksen. In his office on the ship, he does the same pen trick with his hand as the Bishop Android in Aliens (1986).
Lex calling an Alien an "ugly mother..." (with a sound drowning out the latter part due to the PG-13 rating) is a reference to the two previous Predator films, in which Arnold Schwarzenegger (Predator (1987)) and Danny Glover (Predator 2 (1990)) refer to the Predators as such.
The character of Verheiden was named after comic book writer Mark Verheiden, creator of the first Alien Vs. Predator comic series, and the first story involving both species. Contrary to popular belief, the comic was released prior to the infamous shot of the alien "skull" in Predator 2 (1990).
The green glow stick dropped down the shaft contains the same fluorescent liquid used by the effects departments of all the Predator movies as the Predators' blood. According to Predator (1987) director John McTiernan, they stumbled on the effect after unconvincing attempts to make the blood look orange forced the crew to look for alternatives.
The animatronic Queen was controlled by a motion-control rig, which could save her movements digitally. So, if the Queen made a nice looking move in rehearsal, the move could be replayed verbatim in front of the camera.
At the beginning of the film, the readout of the Predator ship is shown reflected in the visor of the Predator's mask, just as in Alien (1979), the readouts of the Nostromo were reflected on the space helmets.
According to Director Paul W.S. Anderson, if they'd filmed in Hollywood, the sets would have cost them twenty million dollars. In Prague, they only cost two million dollars, an important factor in keeping the film's budget down below fifty million dollars.
Paul W.S. Anderson rewarded hardcore Alien and Predator fans by scattering references to the individual franchises within his film. For instance, the opening shot of the movie appears to be a silhouette of the Alien Queen from Aliens (1986), before being completely revealed as a Weyland Satellite.
This is the first Alien film, and also the first Predator film, to get a rating other than an R. This fact led to much backlash from the fanbases of both series, who thought only an R rating could do the cross-over justice. As a compromise, an unrated version was later released on DVD.
The Alien Vs. Predator story crossed over virtually all forms of media before becoming a feature film. There was a successful comic book series, toy line, multiple video games, soundtrack (of the PC game), and even a trading card series.
A pair of what appear to be human skulls are mounted on Chopper's backpack, indicating he has hunted on Earth before. This would also imply it is necessary for a Young Blood to specifically hunt Xenomorphs to become Blooded - other prey such as humans does not suffice.
At one stage, both Peter Weller and Gary Busey were approached to do a cameo as John Yutani, the other founder of the infamous "Weyland-Yutani" Company from the "Alien" films, but Yutani was written out of the script. Interestingly, Busey had already played a different character in Predator 2 (1990) 14 years prior. The Yutani character was later used in the sequel, Aliens vs. Predator: Requiem (2007), this time as a female.
The scene in which Weyland's team discovers the sacrificial chamber inside the pyramid was originally longer than seen in the theatrical cut. After Rousseau and Thomas discuss the hole in the corpse's chest, Sebastian finds a calcified facehugger. Lex and Sebastian then theorize as to what the creature's origin could be. The scene was restored in the movie's unrated extended cut.
At the beginning of the film, the technician in the satellite control station has a "drinking" bird among the Tweety Pie dolls. These are the same birds that were seen on the dining room table in Alien (1979), and the abandoned prison canteen at the end of Alien³ (1992).
Of the three main predators, Scar is the only one to be seen without his mask. As the script required a greater amount of interaction with the character Lex Woods, a wider range of subtle facial movements were built into the characters animatronic face mask. This Predator is supposed to be a much younger specimen, so its skin is much smoother compared to previous movies. The creature's facial skin tones were also made more human and less amphibian, to help audiences associate and bond with the character.
This was a project that had floated around for about ten years. It was only when Paul W.S. Anderson did his verbal pitch to the executives at 20th Century Fox, that anyone showed any real interest. So much so, in fact, that they greenlit the film immediately.
The shot taken from inside the pyramid, of the team approaching the top with their flashlights, references the shot in Alien (1979) of the Nostromo's expedition team walking up to the entrance of the derelict ship.
Around the time of the film's release, it was reported that at a special industry screening, Paul W.S. Anderson had said that the film was always planned as an R-rated movie, and shot that way, but only three weeks prior to release, the studio changed that by severely cutting the film for a lower PG-13 rating. This account has been heavily disputed by original "AVP" writer Peter Briggs. It was later revealed that this "press screening" never actually took place, and was only an Internet rumor started by fans. Anderson has said in interviews, that the film seen in theaters is the version he intended audiences to see. However, to appease the fans, an unrated version with added scenes and gore was released later.
The Antarctic xenomorph queen appears to be much larger than any other Queens seen in the movies and Comics, even outsizing the first Acheron Queen in Aliens (1986). This is most likely due to the fact that she's believed to be centuries old, and had been used in many Yautja initiation hunts. Because of this, it can be said that Queens grow in size the older they are.
The basic bodysuits for all three predators in the film (Scar, Celtic and Chopper) were poured from the same mold before being customized after the fact to make each character appear unique. 16 suits were created, each painted in the same color scheme so that they could be replaced at any time if necessary. As in Predator 2, the armor was created separately, as the script required it to be removed; armor pieces, made from either fiberglass or flexible urethane, were used to customize the suits and create the three individuals. Scar was given longer, telescopic Wristblades, a throwable 'shuriken' and a new sleeker Combistick; Scar's mask was designed to mimic the original Jungle Hunter design.
20th Century Fox wanted Roland Emmerich to direct the film back in the late 1990s, due to the box-office success of Independence Day (1996), but Emmerich turned down the offer, choosing to work on other projects.
On the official poster for the movie, with the Predator in the lower right corner and the alien in the upper left, drooling; the raised black parts of the alien's jaw, along with the opening in its mouth, spell out the letters AVP in an organic version of the font used for the movie's title.
Screenwriter Peter Briggs wrote his original speculative script for "Alien Vs. Predator" in 1991. The script sold overnight, and made him the subject of numerous magazine and book "success story" articles. His version went adrift following studio politics in the wake of executive Joe Roth's departure from 20th Century Fox.
Verheiden is the only character in the film franchise seen to remain conscious while being impregnated by Facehugger; all other victims have been rendered unconscious during this process. Some have theorized that this occurs because he was cocooned at the time and therefore unable to resist. While unique in the film series, several novels have had characters likewise remain conscious during Chestburster implantation, including several individuals in Alien: Sea of Sorrows.
Director Paul W.S. Anderson developed the Shuriken as a replacement for the Smart Disc; while he liked the concept of a thrown Predator cutting weapon, he thought the Smart Disc in Predator 2 (1990) "looked too much like a Frisbee." The Shuriken was based on the traditional Japanese weapons of the same name (colloquially known as "throwing stars"), although with greatly increased size, and the additional ability to be folded away for storage. He also redesigned the shoulder-mounted cannons to appear more bulky and powerful, since he thought that the versions seen in the previous movies looked like a hairdryer.
There's a shot where Lex pulls herself up a cliff. It's filmed exactly like the shot in Alien (1979) where Ripley (Sigourney Weaver) does the same, looking for the Alien, and in Aliens (1986), when Ripley pulls herself out of the airlock at the end. In both shots, the characters are sweating profusely, and one of their hands in front of their faces can be seen.
When one of the explorers is searching the whaling compound, and walks past a door to a building, there is a shot from within the building, in which the red light from the guy's flare comes through the crack in the door to form a flat vertical beam that's picked up by the dust and snow from inside the room, just like the blue-green scanner from the salvage scene at the beginning of Aliens (1986).
The crew tried to keep CGI use to a minimum, as Anderson said people in suits and puppets are scarier than CGI monsters as they are "there in the frame". Roughly 70% of scenes were created using suits, puppets, and miniatures, with both real elements and CGI often used within the same shot (depending on what looked best). The Alien queen was filmed using three variations: a 4.8-meter practical version, a 1.2-meter puppet, and a computer-generated version. The practical version required 12 puppeteers to operate. CGI tails were added to the Aliens and the Queen as they were difficult to animate using puppetry. Anderson praised Alien director Ridley Scott's and Predator director John McTiernan's abilities at building suspense by not showing the creatures until late in the film, something Anderson wanted to accomplish with Alien vs. Predator. He later commented, "Yes, we make you wait 45 minutes, but once it goes off, from there until the end of the movie, it's fucking relentless".
Scar appears to violate Yautja code when he kills Quinn at the bottom of the ice tunnel, even though he is unarmed and injured. However, this kill was acceptable as Quinn had fought an uncloaked Celtic on the surface, had been injured as a result of the engagement and had proven his worthiness in combat. Furthermore, he also knew of the Predators' presence. It could also be that Scar saw this as a 'mercy kill' as he recognised that Quinn had no hope of survival due to his injuries and the cold.
Celtic is the biggest and the leader of the three Predator Young Bloods, with a more elaborate and distinguishable Bio-Mask. Ian Whyte, who played Celtic in the film, said he tried to give the Predator the attitude of an alpha male.
The ship they take to the island is an homage to The X-Files: Piper Maru (1996) (The X-Files), where a French ship called the Piper Maru finds a sunken World War II plane containing the black oil alien. ("Piper Maru" was used because it was Gillian Anderson's daughter's first and middle name.)
It is revealed in the film and its accompanying novelization that the Predators have been coming to Earth for centuries, so it is unknown just how long the Queen may have lain dormant within the Predator pyramid. It is possible she was there for thousands of years.
The mechanism and appearance of the Queen's containment system inside the pyramid is one of the most direct references to the original Aliens vs. Predator comic book series. Her restraints in the film are virtually identical -- albeit iced over - to the restraints used on the Queen in the comic.
Celtic's name is based on the the fact that his mask was modeled after Celtic knot works. Chopper gets his name from the long scimitars he he was given in place of the traditional Predator wristblades. He's also referred to as Gill due to the gill-like styles on his Biomask.
Screenwriter Shane Salerno was the last writer and "closer" on this movie. He worked on the film for fifteen months, including prior to production, through filming in Prague, and all the way through post-production, without receiving the co-screenplay by credit that 20th Century Fox recommended him for to the WGA. Shane has a co-screenplay credit on the novelization of the film, dozens of magazine articles, and many of the original theater posters. He got a full credit for writing the sequel, Aliens vs. Predator: Requiem (2007).
Carsten Norgaard broke a rib during the filming of his fight with Celtic at the mouth of the ice tunnel, but did not attribute the pain to a broken bone at the time. In fact, he continued working for the remainder of the day and all of the following day before realizing the nature of his injury and receiving treatment. At first, he thought that breaking a rib was a sign of dedication to stunt work, until director Paul W.S. Anderson told him that during the making of Mortal Kombat (1995), Robin Shou would sometimes break or bruise at least three ribs during a fight.
In the novelization of Alien vs. Predator, Rousseau reacts much faster to the emerging Facehuggers than in the movie, shooting one of the Eggs as the situation begins to deteriorate. However, the creature within was already airborne by the time the bullet hits, demonstrating their supreme agility.
At one point, David Twohy was once approached by 20th Century Fox back in May 2000, about his availability to write and direct the film, but turned down the offer due to scheduling conflicts. Twohy had once worked on several unused story treatments for Alien³ (1992).
Much like in Alien (1979), the exploration team wears color-coded uniforms - Stafford's mercenaries wear silver coats, the scientists and archaeologists wear yellow coats, and Quinn's drilling team wear orange overalls. The only exceptions are Weyland and Lex, who also wear silver coats (although Lex quickly removes hers to reveal a red winter jacket and pants beneath).
A modification named "Hunter's Moon" for Aliens versus Predator 2 allows players to play in the sacrificial chamber from the film, as well as the rest of the pyramid and Razorback Point on the surface above.
The non-firing G36C (and Desert Eagle) props used in Alien vs. Predator were supplied by airsoft store Wolf Armouries, located in London, England, who later offered to recreate the prop ("bar a few very minor details") for interested clients via their website.
Chopper is so far the only Predator seen to use a Scimitars, although the Super Predators on the Game Preserve Planet used greatly extended, singular Wristblades that are somewhat similar in appearance.
Once the sacrificial chamber becomes "Hived", none of the original hosts' bodies are anywhere to be seen. However, in one scene, the bodies of Thomas and what appears to be Rousseau can be briefly glimpsed in the passage way leading to the chamber, although Adele's jacket is closed whereas it was open when she died. These bodies can be more clearly seen in the "making of" featurettes. The body that is likely Adele is cocooned upside down, while only the orange jacket of Thomas can be seen among the resin. The body that is seen is actually a dummy, like the one used for Joe Connor's body.
Carsten Norgaard had appeared previously in the 1990s in a serious of TV adverts in Ireland for the Norwegian oil company Statoil's Irish chain of petrol stations, as the character "Erik from Oslo". This makes his AVP character's line about drilling possibly a subtle call-back in-joke to one of his earlier acting roles.
Ever since the 1990's, there was been two Alien-related movies every decade. This includes Alien3 (1992) and Alien: Resurrection (1997), moving on to AVP (2004) and AVP: Requiem (2008), and ending with Prometheus (2012) and Alien: Covenant (2017).
The trivia items below may give away important plot points.
Previous movies in the "Alien" franchise (particularly Alien³ (1992)) have established that the Alien creatures take on some physical characteristics of the hosts inside which they gestate. This film ends with an alien "chestburster" emerging from inside a Predator; the creature has green coloration, an obvious resemblance to the Predator's mandibles, and makes the trademark "clicking" noise. The creature has been dubbed a "Predalien", and is the main antagonist in the sequel.
It's not clear in the film if Scar was aware that he was impregnated with a chestburster. A deleted scene was to show that he is and that he attempts to stab himself through the chest with his ceremonial dagger before he dies, but he succumbs to his wounds before he can do so. However this sequence was cut.
Ian Whyte plays all three Predators in this movie, and would go on to appear as the Predator in Aliens vs. Predator: Requiem (2007), as well as the Last Engineer in Prometheus (2012). In all three movies, his characters are either killed or mortally wounded by Aliens. That means that he has been (nearly) killed off five times by an Alien throughout his career.
The reason that a single Alien kills two Predators in such a short period of time is because the trial inside the pyramid is supposed to be a coming of age ritual for specifically selected Predators, who were young (probably adolescents in Predator terms) and relatively inexperienced; also, there were not supposed to be humans running around distracting the Predators (normally, the only humans inside are the ones ritually sacrificed to spawn the Aliens, and they are dead as soon as the trial begins). In contrast, the Predator "Wolf" in Aliens vs. Predator: Requiem (2007), this film's sequel, is a seasoned veteran and manages to kill nearly all of the Aliens he encounters.
When the Predator breaks off an Alien's finger to tattoo Alexa, the other Predators show up at the end, and it's the insignia tattooed on her cheek that saves her life. This is a direct homage to Mark Verheiden's Predators comic book (1991), where it shows the character in the comic book story, who looks a little like Sanaa Lathan. When the character proves her worth by killing Aliens and saving the Predator's life, he tattoos (burns) his personal insignia into her cheek.
Before getting impaled to death, Maxwell Stafford (Colin Salmon) gets pinned against a wall and nearly cut into cubes by the Predator's net weapon. This is remarkably similar to the way his character "One" dies in Resident Evil (2002) (also directed by Paul W.S. Anderson). In that film, he is also cut into cubes, that time by a waffled laser beam passing through his body.
The canon value of this film and its sequel Aliens vs. Predator: Requiem (2007) to both the Alien and Predator franchises has long been subject of debate, since they were made by the original studio but without the approval of the original makers. However, after the release of the Alien prequel Prometheus (2012), it has been confirmed by multiple sources (including Ridley Scott and AvP director Paul W.S. Anderson himself) that the AvP franchise is not considered to be an official part of the Alien universe. Fox studios allowed Scott to present his official backstory to how the Xenomorphs came to be in Prometheus and its sequel Alien: Covenant (2017), no longer making AvP an official prequel to the Alien movie franchise, but taking place in a separate non-canon continuity (similar to how games such as Star Wars: The Force Unleashed (2008) were no longer considered canon when Disney took over the Star Wars franchise). With no such statements issued for the Predator franchise, the AvP movies could still be considered as official parts of the Predator series. Although Predators (2010) purposely chose to ignore the AvP movies, Alexa Woods' Xenomorph tail spear can be briefly spotted in The Predator (2018).
If not including the facehuggers impregnating the characters, an Alien never actually kills a human in the film, the Predators are the only creatures that kill the humans, while the Aliens just kidnap humans for the facehuggers to impregnate. However, one single Alien drone defeats and kills two of the three main Predators around five minutes after the two species meet on-screen for the first time. In fact, this is the only film in the Alien franchise, that does not feature Aliens killing humans.
Director Paul W.S. Anderson was very happy with the old-school practical approach of Visual Effects Supervisor John Bruno. He jokingly stated that if possible, Bruno would try breeding real Predators and Aliens; if that failed, he would first rely on Alien and Predator suits, then on animatronic effects, before considering computer-generated images (CGI). Such was the blending of traditional and modern techniques that they often appear seamlessly within the same shot or frame. For example, in the shot where the Alien jumps on Celtic, both the Predator and the Alien were played by stuntmen in suits; only in the first frames where the Alien launches itself off the wall and the last frames where it lands was the Alien digitally replaced by a CGI effect. In the climax, as the Queen threatens Scar, the Predator is played by a stuntman in a suit, the Queen is a remote-operated animatronic, and her tail is computer-generated.
Scar knows he was impregnated by a facehugger, meaning he carries an embryo in him. At the end of the movie when the queen is chasing Scar , she wouldn't even tried to have killed Scar, as she would know that her child would emerge from its host body. This same thing happened in Aliens(1986) as Ripley and Newt were impregnated as The embryo in Newt broke through her cryochamber. But when face to face with Ripley , the alien doesn't kill Ripley, the alien knows Ripley carries an embryonic queen.
