Dirty Rotten Scoundrels is a 1988 comedy film directed by Frank Oz and starring Steve Martin and Michael Caine as the title characters. Glenn Headley is also featured.

Martin plays a small-time hustler who cajoles Caine, a master of the art, into teaching him the secrets of his craft. When Caine decides there isn't room for the two of them in the same city, a challenge is laid down: the first to con fifty thousand dollars out of innocent Headley will be allowed to stay, while the other must leave.

The film is a remake of Ralph Levy 's 1964 film Bedtime Story starring Marlon Brando and David Niven, and featuring Shirley Jones. Dirty Rotten Scoundrels uses the same script (by Stanley Shapiro and Paul Henning) and most of the same shots as its predecessor, though the ending is changed and some jokes were updated for a 1980s audience. There is debate over which is the better version, though Dirty Rotten Scoundrels is much better known.

A musical adaptation of the film is currently in the works, with music and lyrics by David Yazbek . John Lithgow will portray Caine's character and Norbert Leo Butz will play Martin's. The show is set to debut in January 2005.
