Nicole Kidman is to voice a penguin in George Miller's upcoming animated feature 'Happy Feet'.
Nicole, who also stars in Miller's upcoming 'Bewitched', says it's a very small role.
'Happy Feet' is Miller's first movie since 'Babe: Pig in the City' seven years ago. He previously directed the 'Mad Max' trilogy and 'The Witches of Eastwick'.
Also lending voices to the production are Brittany Murphy, Hugh Jackman, Elijah Wood and Robin Williams. The film will be released in November 2006.
