Trading Places (1983)

Factual error: When Beeks is locked in the cage with the gorilla, it reacts in an overtly aggressive and sexual manner. First, gorillas are shy and gentle creatures. The male gorilla would be scared of him, not the other way around. Second, gorillas identify each other by their smell, and the smell of a female in heat is very specific. Beeks would smell like a horsehair rug and the male gorilla wouldn't be the slightest bit interested.

Even Bigger Black Guy: I mean you beatin' 10 cops? You putting a man in the hospital? How come I don't see no bruises on you?
Big Black Guy: Yeah.
Billy Ray Valentine: 'Cause I'm a karate man! And a karate man bruises on the inside! They don't show their weakness. But you don't know that because you're a big Barry White looking motherfucker! So get outta my face.

Trivia: In every John Landis film, you can see or hear the phrase "See you next Wednesday." In this film, it's a movie poster (starring Lawrence Olivier) right next to Ophelia's bed.

Question: Why are Dan and Eddie in wool sweaters on a tropical beach when the women are in bikinis at the end of the movie?
