Breathless Pegg loved 'Ice Age' role

Simon Pegg struggled with breathing when working on ‘Ice Age: Dawn of the Dinosaurs’.

The actor loved voicing wild one-eyed weasel Buck in the animated sequel but admits he found incorporating noises into his portrayal of the character difficult.

He explained: “There was a lot of yahooing, and impact noises when you are getting hit and the breathing is actually hard. When I was doing the whole sequence when he was flashing back to when he was being chased by Rudy the Dinosaur I had to do some really heavy fast breathing. You actually get pretty-light headed and it’s tough.”

Simon also revealed he was impressed with the similarities between himself and the animated animal he was voicing when he saw the finished movie.

He added to Moviehole: “When I went in for my first session they had a pencil sketch and an animated version of how he would move. Then once you have an idea of the character, you do the voice and then they film you, and they then take a lot from what they get on film, so their animation is inspired by your physicality.

"My wife Maureen said she can definitely see me in him. She thought our facial expressions were very similar.”
