The Life Aquatic with Steve Zissou is Wes Anderson's fourth feature length film, released in the U.S. on December 25, 2004. It was written by Anderson and Noah Baumbach and was filmed in and around Naples, Ponza and the Italian Riviera.

The offbeat comedy stars Bill Murray as Steve Zissou, an eccentric oceanographer. In this ensemble cast, Steve Zissou sets out to exact revenge on the "Jaguar shark" that ate his partner Esteban. Murray's character is both a parody of and homage to Jacques-Yves Cousteau, to whom the film is dedicated.

It was released May 10, 2005 on DVD as part of The Criterion Collection.
