 Benson (Marlon Brando), is a Casanova who despises women and invents all sorts of tricks to bed them and leave them. His favorite one is going through Germany posing as an American GI of Teunonic extraction. Whenever he spots a girl he likes, he takes a Polarod picture of her house, knocks on the door waving the photo and pretending to be on a pilgrimage to this very cottage his grandmother so vividly described. It is an infallible system for a hit-and-run seduction. Benson seems content with his game until he meets Jamison (David Niven), a real operator who has learned to combine sex with money. Jamison poses as an exiled prince and not only gets women to share his bed but also to bestow their jewels on him for the sake of the counterrevolution. Benson decides to corner Jamison s market on sex plus finance. A contest develops, and whoever wins will dominate a small Riviera resort as "King of the Mountain," the film s original title. Remade in 1988 as "Dirty Rotten Scoundrels."
