Brad Pitt and Matt Damon are to lend their voices to penguin sequel Happy Feet 2.
The Hollywood hunks - who star together in the Ocean's movies - have been signed up to voice unknown characters in the singing and dancing animation about the flightless birds, Movieline has revealed.
Elijah Wood and Robin Williams, who voiced starring roles in the first hit movie, are returning for the follow-up, as is director George Miller.
Brittany Murphy - who tragically died last month aged 32 - was also part of the original cast.
Happy Feet 2 is currently in production and is due for release in November 2011.
