Simon will be the voice of 'Buck' in the new animated feature Ice Age 3: Dawn of the Dinosaurs, as reported on Empire Online.

QUOTE
The story sees Buck help mammoth Manny (Ray Romano), sloth Sid (John Leguizamo) and sabretooth tiger Diego (Dennis Leary) when they fall into the lost world beneath the Ice Age where dinosaurs still roam. Buck has a Captain Ahab-alike obsession with the Baryonyx dinosaur Rudy, who's the reason he's one-eyed and whose tooth he carries with him.
