Trivia: During the final battle, Lyle Wainfleet's AMP Suit gets knocked down and crushed by a charging Hammerhead Titanothere. Wainfleet utters a Wilhelm scream just before he's crushed. (02:21:05)
Trivia: In the final battle scene, right after Jake's grenade blows up one of the shuttle's engines, the two pallets of explosives in the shuttle slide together, crushing a soldier between them. He utters a Wilhelm scream. (02:23:10)
Trivia: During the end credits the flying shots are recycled from the beginning and other ikran flying scenes, but reversed. Right as James Horner's name is displayed you can see a shadow of an ikran. This is the same shot used when Jake first rides his ikran and he narrates "I may not be much of a horse guy." Jake, Neytiri, and ikrans are removed, but Neytiri's ikran's shadow remains on the foreground rock left.
Trivia: When Quaritch gives his "You are not in Kansas anymore" speech, the window in the background resembles an American flag. The horizontal window slats are the red stripes, the spaces between them are the white stripes, and the piece of machinery in the corner is the union (the blue part with the stars). This is a subtle reference to the film Patton, in which Patton gives a speech standing in front of an American flag at the beginning of the movie. (00:06:45)
Trivia: In the scene where the large space shuttle-style ship is landing on Pandora at the start (that carries Jake and co.), we can see shots of the ground. One panning shot shows an extremely large mining vehicle that has large arms with several buckets attached to the round sides of cylinders on each arm. The machine is huge and looks unreal, but it is actually a replica (or of similar design) to a digging machine that exists today. It was designed by Krupps, and is the largest digging machine in the world. It can be viewed here: http://www.swapmeetdave.com/Humor/Workshop/Trencher.htm. (00:04:00)
Trivia: Sigourney Weaver saw her character Grace in the film as James Cameron. She stated in an interview "I teased him because to me I'm playing Jim Cameron in the movie as this kind of brilliant, approach-driven, idealistic perfectionist. But that same somebody has a great heart underneath. So I have to say I was always kind of channeling him."
Trivia: Cameron wrote the film with environmental, political and social issues in mind, and as a result of his stance on climate change, only allowed vegan food on set.
