Trivia: When the grandchildren and Grant are crawling above the drop-down ceiling to flee from the raptors, the raptors at one point have "squares" of light shining on them. If you look closely at this light, these "squares" of light are not really squares, but the letters A T C G, the DNA sequence abbreviations.
Trivia: One of the fans in the stands is actually Daniel "Rudy" Ruettiger, and he is listed in the credits as "fan in the stands" who can be seen in the last few minutes of the film. You can see the real Rudy sitting directly behind the actors playing Rudy's parents, and he's wearing a plaid flat cap and a dark colored coat with a thick light beige fur collar/lapel. About 15 seconds after the game ending tackle, Ned Beatty, the actor playing Rudy's father, turns around and grabs the real Rudy by his coat collar/lapel, then slaps his chest in joyful celebration.
