It seems to me that I have heard somewhere that this movie was done once previously with David Niven playing Michael Cain's part and either Paul Newman or Marlon Brando playing Steve Martin's part. Maybe I heard of a similar movie or story line with a different title. Does anyone know?
shareIt called Bedtime Story,
shareI believe the parts were played by David Niven and Jerry Lewis. As I watched I knew I had seen the story before.
shareBedtime Story (1964) stars David Niven (Lawrence) and Marlon Brando (Freddy).
In the Dirty Rotten Scoundrels DVD director's commentary, Frank Oz makes mention of the movie several times.
It's not a scene-for-scene remake though. Check out the movie's entry on this site.
