Actor William Moseley has told how he worked out to get ready to star in new film The Chronicles Of Narnia: Prince Caspian.

The actor plays Peter Pevensie in the film, which has premiered at the O2 Arena in London.

He said he trained for three and a half months leading up to the film, boxing and running eight miles every other day.

He said at the premiere: "It's mind-blowing. It is really beyond anything I could have imagined. The fans came here to see us for two minutes. I wouldn't have done it."

Anna Popplewell, who plays his sister Susan in the eagerly anticipated movie, said: "It's mental, mental, chicken oriental is what I think.

"It's really nice to bring the film home for us British actors and to be with a home crowd."

Liam Neeson, who voices the character Aslan, was also at the glitzy premiere in London.
