Trivia: Nicolas Cage has no speaking lines throughout the entire movie.
Trivia: M3gan's scenes were done with an actual person wearing a mask (with some CGI being used to animate the eyes and face.) The girl's name is Amie Donald, and she is an accomplished gymnast and dancer, and in the scenes with the hallway dance and running on all fours were not special effects, Amie actually did those moves.
Trivia: The trivia and in jokes abound in this film. Firstly, you have Janet Leigh (Jamie Lee Curtis' mother) playing Norma (reference to Psycho) and complaining that the "showers are blocked again" (second reference to Psycho). In her last scene in the film, Janet Leigh is about to get into and drive away in the same car that she used in Psycho.
Trivia: According to the DVD commentary, the entire budget for Underworld was the same as the highway chase scene in The Matrix Reloaded.
Trivia: The filmmakers originally had an ending in which Alex grabs the cable that lies on Clear's car, Alex catches fire and dies. Then Clear gets her baby and Carter survives. The test audience didn't like this, so the filmmakers shot another ending in which Alex is decapitated by a crashing police helicopter. But again, the test audience didn't like the fact that Alex dies, so they shot the finish with the billboard, which took 6 days to film and cost nearly $2,000,000.
Trivia: Sigourney Weaver actually makes the basketball shot. Even though the ball is out of shot for a second, she made the shot with no assistance. The shot cuts quickly because Ron Perlman dropped character in celebration, which can be seen in deleted scenes online.
Trivia: When they are preparing and listening to the tape you can see a bit of smoke in the air. There had been an extended scene where they had been smoking pot and joking around. However, they used real pot when filming and much of what was shot ended up being unusable as a result. This is according to Bruce Campbell's Commentary to the DVD.
Trivia: One should really stay to the very end of the credits, as Johnny Depp (Mort) sings an amusing little tune.
Trivia: Stay after the credits. There's an additional scene where John goes to visit Chas' grave and leaves a lighter, then as he's walking away you see Chas with wings and he flies up into the sky. (01:54:40)
Trivia: Right at the end, in fact the very last frame, you can see a face in the snow as the shot fades out.
Trivia: Steven Spielberg "interviewed" over 100 trucks before finding the forboding, evil looking one for the movie.
Trivia: In the scene near the end of the movie, there is a board meeting on the tarmac. The Chairman of the Board is Stephen King who is the author of The Langoliers. (02:10:15)
Trivia: There are two different endings to this movie. In the first one (released on video and DVD in the US), the shark (inexplicably) explodes after being rammed by the boat and sinks to the bottom in a reuse of footage from "Jaws." When the camera cuts back to the survivors floating in the water, we see that Mario Van Peebles, though badly wounded, is alive after all. In the second ending (which can be seen on American Movie Classics in the US), Mario Van Peebles does not survive his fall off of the boat; when he falls, he lands in the shark's mouth and is killed. Also, when the boat rams into the shark, it does not explode but is more "realistically" impaled, blood pouring from its mouth as it dies. After the survivors are knocked off the boat, there is a shot of ship and shark sinking to the bottom, prow of the ship stuck in the side of the shark.
Trivia: The scene where Barbara crashes the car into the tree wasn't scripted originally; an accident that put a large dent in the car before the scene was shot prompted George Romero to re-write the scene in such a way that the dent is justified.
