Robin Williams returns for Happy Feet sequel. Robin Williams has announced that a sequel to Happy Feet is in the works. The 58-year-old actor, who voiced two animated penguins in the original film, said that director George Miller is already preparing the follow-up: “I go to Australia in January. He’s going to record there, which is great. He’s a very sweet man. He (Miller) goes, ‘Robin, I think we’re gonna do another one’. Great, George. It’s so great, because you realise George Miller, he did all those Road Warrior movies, and then he does this penguin movie.” Williams will once again voice the characters of the South American penguin Ramon and baritone-voiced Lovelace.
