Ein perfekter Seitensprung (1979)

An Almost Perfect Affair is a 1979 romantic comedy film directed by Michael Ritchie and starring Keith Carradine and Monica Vitti. The plot is about an affair between filmmaker Hal Raymond and film producer Freddie Barone's wife Maria, set during the Cannes Film Festival. Despite several favorable reviews the film did not perform well upon release, and Paramount Pictures quickly withdrew it from circulation. It thus has a reputation as a 'lost' movie, although it has since been broadcast on television and is now available on DVD.
