Williams plays seal named Cletus

LOS ANGELES, June 28 (UPI) -- Robin Williams may star as The Joker in the next "Batman" film, but it is his turn as a seal and two penguins that has the Hollywood actor excited.

The comedian and actor is one of many Hollywood stars who have lent their voices to animated animals in the upcoming computerized feature film "Happy Feet," IGN FilmForce.com reports.

"Yeah, that's the best," Williams told the Web site, "I do three different characters ... One is an Argentinean Gilly penguin who is, (in his best Argentinean voice) like this, very powerful but very small as you will see from the World Cup."

Joining Williams in the voice cast are actors Hugh Jackman, Nicole Kidman, and the "Lord of the Rings" trilogy star Elijah Wood.

Williams describes the Warner Bros. feature as being a combination of the documentary "March of the Penguins" and theatrical show "Riverdance," the Web site reports.

The film is scheduled for a Nov. 17. release.
