Chris Williams is now on board as a co-director, and Roy Conli has joined the film as producer. Williams -- who will work with initial director Don Hall -- is a Disney veteran dating back to a story credit on 1998's "Mulan," and previously co-directed 2008's "Bolt," an Academy Award nominee. Conli also has years of Disney experience, as a producer on "Tangled," "Treasure Planet" and "The Hunchback of Notre Dame."
The first Disney animated feature based on Marvel Comics concepts and characters, "Big Hero 6" was created by Steven T. Seagle and Duncan Rouleau during their run on "Alpha Flight" in the late '90s.
"What I loved most of all was the emotional story of a 14-year-old genius named Hiro who loses his big brother, and a robot named Baymax that heals his broken heart," Don Hall said this past August while previewing the film at Disney's D23 Expo. "That feels like the makings of a Disney movie."
"Big Hero 6" is scheduled for release on Nov. 7, 2014. No voice cast has yet been announced.
