Trivia: The English version of the theme song is not a remixed version, as the previous four movie themes were - this theme has the same music and tempo as the TV version. The composers did not create a second verse to the song "Master Quest," so it has the same lyrics as the TV version all the way through.
Trivia: John Rhys-Davies is missing the end of his middle finger on his left hand due to a farming accident as a child. The make-up artists made artificial, gelatin fingertips for him to wear in the movies. Davies one day, cut the tip in half, put 'blood' in it and closed it up. He went over to Peter Jackson (unaware of the gelatin tip) and said, "Boss, I've had an accident, look what happened". Jackson saw a small cut, but Davies bent the tip back and it split open, gushing.
Trivia: Adrian Brody insisted on learning to play the piano himself because he detested the idea of him being in a long shot pretending to play the instrument and then the camera showing someone else's hands on a close up shot actually playing. He said he hated that, not just for him, but on any other film that had such a scene. So he went and took lessons, practicing for hours on end.
Trivia: The song that Landon is listening to when he pulls up to the cement factory is by Shane West's own band "Jonny Was" (then "Average Joe"). The song appears on the soundtrack under the band name "West, Gould, & Fitzgerald".
Trivia: The big speech from "Couldn't you find anyone worse? A child molester..." to the bit where Stu is shot was filmed in one take. Colin Farrel did everything and surprised himself and the crew.

Trivia: When the alien's hand comes out of the coal grate for Morgan, if you look closely you will see that the hand was already through the grate and the alien was using its colour changing abilities to hide. So if you look very closely you will that that the hand comes UP from the grate and not through it, and if you look VERY carefully you can see the outline of the hand even before Morgen says "What?"
