Dean DeBlois is a Canadian writer, director, and producer known best for having co-written and co-directed Disney's Lilo & Stitch (2002) and Dreamworks' How to Train Your Dragon (2010), both Oscar nominated. While working as an assistant animator and layout artist for Hinton Animation Studios in Ottawa, Ontario, DeBlois simultaneously attended Sheridan College's three year Classical Animation program. Upon graduation in 1990, DeBlois was immediately hired by Don Bluth Studios in Dublin, Ireland. There, he cut his teeth as a layout artist, character designer, and storyboard assistant to Don Bluth on such films as Thumbelina (1994) and A Troll in Central Park (1994)." In 1994, DeBlois left Ireland to 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 (1998).
