A Fish Called Wanda (1988)

Continuity mistake: After Ken reverses the steamroller after running Otto over with it, you can see a red patch signifying his splattered body in front of the roller. However, a few scenes later, Otto is seen alive. (Otto was originally meant to die, until test audience feedback influenced a change of mind on the part of the filmmakers.)

Otto: Asshole.

Trivia: John Cleese's character name, Archie Leach, was Cary Grant's real name (Archibald Leach). John named his character himself as a tribute because they were born in towns near to each other.
