His first animation job was as a character layout artist on King of the Hill, and later as an episode director for Avatar: The Last Airbender. He then joined the Star Wars franchise as the supervising director of Star Wars: The Clone Wars, and later co-created and executive produced Star Wars Rebels.
On September 2016, he was promoted to oversee all Star Wars animation projects, including Star Wars Resistance. In October 2018, he was announced as an executive producer and episode director on Jon Favreau's live-action show, The Mandalorian.
- King of the Hill (1997 — 1999) as character layout artist
- Avatar: The Last Airbender (2005) as episode director
- American Dragon: Jake Long (2005) as storyboard artist
- Star Wars (2008 — present) as overseer of Lucasfilm Animation
Dave Filoni provides examples of:
- Armed with Canon: As long as he has permission from the Lucasfilm Story Group to do so (and discussing it with Lucas back in The Clone Wars), he and the other writers can put whatever they want in the Star Wars animated shows. Not only can they create original work, but they can recanonize/decanonize and adjust ideas from Legends, especially now that as of 2014, the New Expanded Universe has plenty of blanks to refill.
- Author Appeal:
- He likes Plo Koon and wolves, hence why Plo Koon's clone battalion in The Clone Wars is called the Wolfpack and is led by Commander Wolffe. He's even apparently cosplayed as Plo at least once according to the first season box-set for The Clone Wars.
- Ahsoka's design was partly based off of San from Princess Mononoke. Further amplified when he revealed his personal headcanon of Ahsoka escaping Order 66 with the help of giant wolves whose legs seemed to be like trees, and a picture he drew of Ahsoka and Rex riding giant wolves in the aftermath of Order 66, though neither are canon. However, Filoni got around to making canon images for the Topps trading cards showing what happened to Ahsoka after the end of her major role in Rebels — she walks through a mysterious door with wolf designs on it, which ties into...
- Lothwolves, giant wolves native to Lothal, serve as a Chekhov's Gunman in Rebels, where they're mentioned in a nursery rhyme joke early on and are hinted at in ancient art on Lothal. A pack of them appear in the flesh in Season 4 to help the heroes.
- He's also a cat person, too, which is why there's emphasis on lothcats in Rebels. The tooka species is named after his late cat, Tuuk. (Mar Tuuk from The Clone Wars was also named after Tuuk.)
- He likes Godzilla, hence the Zillo Beast arc and the unreleased sequel arc to it in The Clone Wars. Commander Jun Sato from Rebels is named after two staff members in the Godzilla franchise.
- Creator's Favorite:
- Descended Creator: He is the voice of Embo the bounty hunter in The Clone Wars, though it can be hard to tell due to sound editing. As a bonus, the character also sports a Nice Hat, just like his voice actor! He also voices the occasional incidental character, more often in Rebels. It's revealed in the credits of the final episode of Rebels that he's voiced Chopper the entire series.
- Promoted Fanboy: Most definitely. He went from merely being a Star Wars fan to working on two animated shows (and now future ones included, now that he's pretty much supervising all of them as of September 2016) set within the universe.
