The son of a Viking chief must capture a dragon in order to mark his passage into manhood and prove his worthiness to the tribe in directors Chris Sanders and Dean DeBlois' adaptation of Cressida Cowell's popular children's book "How To Train Your Dragon."

Gerard Butler, America Ferrera, Jonah Hill, Jay Baruchel, and Christopher Mintz-Plasse provide voices for the DreamWorks Animation production.

A winner with audiences and critics alike, the action-adventure soars onto DVD and Blu-ray with even more fun, excitement and, of course, more Dragons!  

Giving fans more of what they loved, DreamWorks Animation unveils "Legend Of The Boneknapper Dragon," an all-new animated adventure that introduces a brand-new, never-before-seen dragon and features the original voice cast.

The bonus adventure will be available for a limited time only in a Double DVD Pack and also in a Blu-ray/DVD Combo pack.  The Venice Film Festival Persol Award-winner for "the most creative 3D film of the year," "How To Train Your Dragon" will also be exclusively available on Blu-ray 3D as part of Samsung’s 3D starter kit for a limited time period.
