Early life

DeBlois was born and raised in Aylmer, Quebec, Canada.^[4] As a boy, he was interested in comic books, which he later said influenced his drawing ability, imagination and storytelling. Growing up in poverty, he would visit a nearby smoke shop on weekends, where the proprietor let him read comics for free. Memorizing them, he went home and drew.^[5] DeBlois attended Darcy McGee High School.

Career

DeBlois began his career as an assistant animator and layout artist for Hinton Animation Studios/Lacewood Productions in Ottawa, Ontario, while simultaneously attending Sheridan College's three year Classical Animation program in Oakville, Ontario. From 1988 to 1990, DeBlois contributed to such productions as The Raccoons (TV series), The Teddy Bears' Picnic (TV special), and The Nutcracker Prince (feature animated film).

Upon graduation from Sheridan College in 1990, DeBlois was hired by Sullivan Bluth Studios in Dublin, Ireland. There, he worked as a layout artist, character designer, and storyboard assistant to Don Bluth on such feature animated films as A Troll in Central Park and Thumbelina.

In 1994, DeBlois left Dublin for Los Angeles to begin work for Walt Disney Feature Animation as a storyboard artist, where he worked alongside his frequent collaborator, Chris Sanders, as Head of Story on Mulan. Shortly thereafter, they re-teamed to create Lilo & Stitch. DeBlois left production on Atlantis: The Lost Empire in order to work on Lilo & Stitch.^[6]

Following its release in 2002, DeBlois sold several original live action feature film projects to write, direct, and produce, including an Irish ghost story titled The Banshee and Finn Magee,^[7]^[1] a psychological thriller titled The Lighthouse^[8] (not to be confused with the 2016 and 2019 films titled The Lighthouse) and a family adventure series titled Sightings,^[9] which were optioned at Walt Disney Pictures, Touchstone Pictures, and Universal Studios respectively.

DeBlois' feature-length music documentary film Heima chronicles the homecoming concert of Iceland's Sigur Rós.

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.^[10]

During that same time, DeBlois also directed another feature-length music film for Sigur Rós front-man Jónsi, entitled Go Quiet, as well as a feature-length concert film entitled Jónsi: Live at The Wiltern.

DeBlois wrote and directed the fantasy/action film How to Train Your Dragon 2, a sequel to the original, which was released on June 13, 2014, followed by How to Train Your Dragon: The Hidden World on February 22, 2019.

On September 23, 2019, DeBlois was attached to write and direct a film adaptation of the Micronauts.^[11]

In February 2023, a live-action adaptation of How to Train Your Dragon was announced, with DeBlois set to write and direct, making the film his live action debut.

Personal life

DeBlois is openly gay, and told The Advocate that people in the industry "knew that one of us was gay" but mistakenly assumed it was his heterosexual writing partner Chris Sanders, because DeBlois "hobbled in there looking like a redneck".^[12]
