A Fish Called Wanda(1988)
Wanda Gershwitz (Jamie Lee Curtis) has several very good friends...The debonair Georges Thomason (Tom Georgeson), the stuttering animal lover Ken Pile (Michael Palin), and the brick-stupid Otto (Kevin Kline). The 4 of them have teamed up for a diamond heist. When George moves the diamonds, crosses and double crosses abound. The only person who can help sort it out, albeit unknowingly, is Georges' lawyer Archie Leach (John Cleese).
