Revealing mistake: When Frank and his wife Eva step out of the chapel after getting married, it cuts to a crowd of photographers. In the background, several modern minivans drive by, including a white one with AVIS written on it.
Revealing mistake: Frank pulls up to his buddy's house where he's offered a bribe of a ski chalet. When he gets out of the car there are visible snow flurries. The scene moves to the living room that overlooks a lake. The trees are all lush and green in the background - obviously not winter.
Suggested correction: That was Richie, not Frank, who was offered the bribe.
Factual error: A few moments after the 20% rent deal for $1 in the cafe you can see a 747-400 (or later) in the sky, the winglets identify it as such. The 747-400 had its maiden flight in April 1988. That scene plays in 1968.
