Robin: Penguin sequel 'beautiful'
Robin Williams believes Happy Feet 2 is "better" than the original movie.
The veteran comic actor does double-duty as the voices of both Lovelace and Ramon in the Antarctic-set animated sequel.
And he says the success of the first movie, and the promise of the second, is down to director George Miller.
"He kicked it, technically, musically and I think theatrically," he said.
"It turned out really well and I think it's as good as the first one, if not better."
The movie sees Mumble, the penguin star of the original film, grown up and trying to bond with his young son Erik, who refuses to dance.
"It's got some really beautiful moments, there's an aria near the end that's quite gorgeous," Williams revealed.
