Revealing mistake: Right at the end of the film when Sam, Patrick and Charlie are driving through the tunnel, when Charlie begins to stand up on the back of the truck, look slightly beneath his flapping jacket and you can see the safety wires attached to him.

Factual error: In all of the cafeteria scenes, the food pyramid posters that can be seen on the walls are the updated 2011 versions, not the ones they would have had in 1991 and 1992.
Trivia: When Brad was telling his friends he got jumped by some kids, Patrick asked, "Where, Schenley Park? Patrick asked Brad's friends, "Do you guys know about Schenley Park?" People who are not familiar with the park may not know if his implied reference to homosexual activity was true. Schenley has been long-recognized as a gay "hook-up" place. Gay male prostitutes "cruise" around the park. Some men drive around with their car door OPEN - anyone can jump in to hook-up. It's also a joggers' park. (01:10:57)
