Just a little anecdote about this film I think is worthy of mentioning:

It's a Hollywood Urban Legend that "The Jerk" is the favorite movie of filmmaker Stanley Kubrick, and when he initially conceived of his 1999 film "Eyes Wide Shut", it was with Steve Martin in mind for the Tom Cruise role.

Sure, it sounds far fetched, but I think when you watch "The Jerk" you can easily imagine it being someone's favorite movie - From that point it's just whether or not you could accept it as Kubrick's. I think I can.
