Boasting one of the funniest casts in history, A Fish Called Wanda is a tale of crime and betrayal as the four participants in a jewelry heist all plot different ways to keep the loot for themselves. Everything comes unhinged via increasingly cartoonish stunts and set pieces, like Kevin Kline torturing Michael Palin by eating all the fish in his aquarium. Palin later responds by running Kline over with a steamroller. All of this is to say nothing of John Cleese prancing in his underwear.
Kline won an Oscar for his performance, but the entire cast shines. This is the epitome of new screwball comedy.
