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: At the end of the movie, when the hitman comes to kill Bernie for one last time, Larry, Gwen, and Richard start running from the hitman and Gwen has her hat in her hand. They run over to the stereo and she drops it somewhere over by there. In later shots, however, you can see Gwen's hat lying right next to Bernie in front of the staircase.
Larry Wilson: What kind of a host invites you to his house for the weekend and dies on you?
Trivia: Bernie's two story house was built specifically for this movie at a state park in North Carolina, but was torn down right after filming, as per the agreement before filming.
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.
