Elijah Wood has admitted it was strange becoming a "parent" on screen for the Happy Feet sequel.
The Lord Of The Rings actor returns as the voice of Emperor penguin Mumble, who had to learn to tap dance when he realised he couldn't sing to find a mate, in the original.
In Happy Feet Two he's all grown up and now has a son with Gloria (voiced by pop star Pink) called Erik, who can't dance. Ashamed, Erik runs away and meets The Mighty Sven (voiced by Hank Azaria) - a penguin who can fly.
Elijah admitted it was surreal going from being the child to a father in just five years, especially one who's having problems with his son.
"At the beginning of the movie you find Mumble quite confident, everything sussed out and doing really well as a father," the 30-year-old said.
"Then he suddenly realises he can't connect with his son like he thought he would, tries a variety of different things and they don't work, and he sort of fumbles.
"Elizabeth Daily, the actress who was playing my son during recording, would make my job so easy because the voices she's capable of are extraordinary. It endeared me to her and made me want to be a better father!"
