Factual error: In the lunch scene outside their office, Larry and Richard are at the food stand and notice Bernie walking into a building. The entrance awning reads "East 70th Street". As they walk away the street sign behind them reads "52nd Street". Apparently they must have superhuman vision which allows them to see 18 blocks away.
Weekend at Bernie's (1989)
1 factual error - chronological order
Directed by: Ted Kotcheff
Starring: Andrew McCarthy, Jonathan Silverman, Catherine Mary Stewart, Terry Kiser
Continuity mistake: Right before Richard discovers that Bernie is dead and Larry is talking about drugs becoming a career, "I watch the news. I read." There is a side/back view of Larry talking and neither his gestures or his mouth line up with what he is saying.
Security Officer: Hot enough for ya, Larry?
Larry Wilson: No, Harris! Why don't you turn up the heat?
Security Officer: OK, I'll tell the engineer.
Trivia: The movie's director Ted Kotcheff has a small part as Richard's father who comes out in his underwear as Richard and Gwen are making out on the couch.
Answer: He says the Italian word "cornuto." Basically insulting Bernie for sleeping with Vito's girlfriend, which is why the hit was put on him in the first place.
