Directed by: John Cleese, Charles Crichton
Starring: John Cleese, Jamie Lee Curtis, Kevin Kline, Michael Palin
Continuity mistake: When John Cleese has removed his clothes and the tenants of the flat come into the room, a quick rear view show that he has blue underwear on, when he's supposed to be naked. (01:14:46)
Suggested correction: This is barely visible on the full screen version. When the picture is properly matted for widescreen, it is not visible at all.
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.)
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.
