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: The guy who played No. 75 (the one who starts chanting "Rudy") is the only actual Notre Dame football player in the movie. He is Peter Rausch, freshman class of 1987. Rausch was a highly recruited defensive lineman from Fort Meyers, Florida in 1987, but played very little due to injuries and health problems (cataract surgery, appendectomy). Rausch had already completed his eligibility, or his appearance in the movie would have been an NCAA violation.
