George Miller isn't sticking any old voices in his follow-up to Happy Feet: he's going to Matt Damon and Brad Pitt to voice the singing/dancing penguin sequel.
According to the team over at Movieline, the actors - who are normally seen on screen together only in the Ocean's movies - have signed on to voice unknown characters in the new film.
Elijah Wood and Robin Williams are, somewhat naturally, still attached, and Miller is deep into getting the thing made ready for a release in November 2011.
