There's a Girl in My Soup (1970)

Description[from Freebase]

There's a Girl in My Soup is a 1970 British comedy film, directed by Roy Boulting and starring Peter Sellers and Goldie Hawn. Sellers appears as Robert Danvers, a vain, womanizing and wealthy host of a high-profile cooking show. He meets Hawn's character, a no-nonsense American hippie living with an English rock musician in London, and, to everyone's surprise, falls for her. She moves in with him, and accompanies him on a trip to a wine festival in France. Meanwhile, her rock musician boyfriend decides he wants her back. Sellers' catchphrase in this film is: "My god, but you're lovely" -- which he sometimes says to his own reflection. The film is based on the stage comedy, There's A Girl In My Soup, written by Terence Frisby, produced by Michael Codron, directed by Bob Chetwyn and starring Donald Sinden, Barbara Ferris and Jon Pertwee, which ran for six years in the West End, from 1966 to 1972, including three years at The Globe Theatre (now The Gielgud) breaking records to become London's longest-ever running comedy. This record was later broken by No Sex Please, We're British and then Run For Your Wife.
