"The Hangover's" Zach Galifianakis in "The Incredible Mr. Limpet"

A milquetoast man, Henry Limpet is transformed into an animated fish that helps the U.S. Navy fight German submarines during World War II. He also falls in love. We know, we know, it’s hard to imagine a sillier premise for a film.

But in 1964, Don Knotts starred as the character in the film “The Incredible Mr. Limpet.” And according to a post yesterday on the LA Times 24 Frames blog the movie will be re-created in a live-action/CGI hybrid film in 2011. This time it looks like “Hangover” star and funnyman Zach Galifianakis will be playing Henry. Warner brothers is reportedly in talks with Galifianakis about the role, after Johnny Depp turned it down.

Galifianakis, who was recently nominated for Breakout Star of the Year at the MTV Movie Awards, is also slated to appear in “Dinner for Schmucks” due out next year.
