Dean DeBlois is a Canadian film director, film producer, screenwriter, and animator. He is best known for co-writing and co-directing the Oscar-nominated animated films Lilo & Stitch for Walt Disney Animation Studios, the How to Train Your Dragon film trilogy for DreamWorks Animation, and directed the Sigur Rós documentary/music film Heima. In 1994, DeBlois left Dublin for Los Angeles to begin work for Walt Disney Feature Animation as a storyboard artist, where he soon replaced his frequent collaborator, Chris Sanders, as Head of Story on Mulan. Shortly thereafter, they re-teamed to create Lilo & Stitch. In October 2008, DeBlois returned to feature animation to co-write and co-direct DreamWorks Animation's then-troubled How to Train Your Dragon, once again re-teaming with Sanders. The duo re-envisioned the film's story and shepherded the production to its March 2010 release. The resulting film became the studio's top-grossing film in North America outside of the Shrek franchise.
