Gerard Butler, America Ferrera, Jonah Hill, Jay Baruchel and Christopher Mintz-Plasse have all signed on to voice roles in DreamWorks Animation's CGI fantasy feature "How to Train Your Dragon" reports the trades.

Based on Cressida Cowell's first novel in the children's book series, the story centers on the timid son of a Viking chief who must capture and train a dragon in order to be initiated into his tribe.

Baruchel will voice the boy, named Hiccup Horrendous Haddock the Third, who is saddled with an undersized and uncooperative dragon.

Butler is the father and chief of the tribe, Stoick the Vast, while Ferrera voices Astrid, who partners with Hiccup for the initiation.

Hill will play Snotlout, a bully who thinks he should be the next chief, and Mintz-Plasse portrays Fishlegs, a Viking big in size but small in brains.

Peter Hastings is directing the project, which is currently scheduled for a March 26th 2010 release.
