A new teaser trailer has been released for DreamWorks Animation's newest 3-D adventure movie, How to Train Your Dragon. Based on Cressida Cowell's 2003 book of the same name, the movie tells the story of a young Viking boy named Hiccup (voiced by Jay Baruchel) who befriends a dragon rather than hunting it down and killing it like the others in his village. Gerard Butler, America Ferrera, and Baruchel's Knocked Up co-star Jonah Hill also lend their voices.
