Storyboarding has officially begun for DreamWorks Animation’s upcoming How to Train Your Dragon sequel, according to The Hollywood Reporter. The film is intentionally being written as the second chapter in a planned trilogy. “There are certain characters and situations that come into play in the second film that will becomes much more crucial to the story by the third,” director Dean DeBlois said. “It’s my way of guaranteeing that it is not another adventure that we throw the same five or six characters into, that it feels like part of a larger story.” Fans of the original movie will have a long time to wait, though, as the sequel is currently set to hit theaters in 2014.
