There’s A Girl In My Soup (1970, U.K.)

Two unique comic talents, the brilliant Peter Sellers and the effervescent Goldie Hawn, join forces in this saucy romance. 

Hawn plays Marion, a recently dumped 19-year-old and American tourist in London.  So a TV chef and self-styled Casanova (Sellers) invites her to crash at his bachelor pad.  While he’s a committed lady-killer, Marion turns his life upside down.  To his surprise, he finds himself falling in love with his winsome house guest!
