Penelope is a 1966 American comedy caper film directed by Arthur Hiller, and starring Natalie Wood, Ian Bannen, Peter Falk, Jonathan Winters, and Dick Shawn.

George Wells' screenplay was based on the 1965 novel of the same title, written by Howard Melvin Fast under the pseudonym E.V.

While the police, including Lieutenant Horatio Bixbee (Peter Falk), rush to get to the bank, Penelope escapes in a red wig and yellow suit.

Con artists Sabada (Lila Kedrova) and Ducky (Lou Jacobi) immediately recognize the suit as an original designer outfit from Paris, and purchase it for a mere $7.

She says it began in college when a professor (Jonathan Winters) lured her into his laboratory and attempted to rape her, but she escaped, leaving her dress ripped off in the process.

Gregory wants to return the stolen money to the bank, but panics when he hears police cars arriving.

The psychiatrist explains the dinner guests denied recognizing the stolen items because they would lose the fraudulently inflated insurance claims they collected.

The Los Angeles Times called it "that rare addition to whodunnit fiction, an original and unusual plot told with wit and intelligence".
