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.
Trivia: If you listen very carefully to the part where Al MIchaels says, "Do you believe in miracles? YES...", you'll notice that it's from the original broadcast of the game in 1980. All other play-by-play was re-done by Michaels as the movie was produced. The reason they used the original 1980 broadcast for just that specific moment is that Michaels had a difficult time recreating the emotion and excitement he felt when shouting it as it really happened.
Trivia: When Derice is applying for loans at different banks, the wall behind each bank manager is always the same wall! The plants and decorations are different, but it's the identical wall.
Trivia: Near the end of the film in the locker room prior to the championship game, Coach Dale makes reference to the players on the other team whose names are written on a chalkboard. If you look closely at the list of names, you'll see that they are the last names of the actors that portray the Hickory players (Poole, Schenk, Boyle, etc).
