A Fish Called Wanda is a 1988 heist comedy film directed by Charles Crichton and written by Crichton and John Cleese. It stars Cleese, Jamie Lee Curtis, Kevin Kline, and Michael Palin. The film follows a gang of diamond thieves who double-cross one another to recover stolen diamonds hidden by their jailed leader. His barrister becomes a central figure – and jealousies rage – as femme fatale Wanda seduces him to locate the loot.

The picture grossed over $188 million worldwide, becoming the seventh-highest-grossing film of 1988. It received three nominations at the 61st Academy Awards: Best Director, Best Original Screenplay, and Best Supporting Actor for Kline, which he would go on to win. A spiritual sequel, Fierce Creatures, was released in 1997. The British Film Institute ranked A Fish Called Wanda the 39th-greatest British film of the 20th century.
