Warner Bros. has put its long-in-development “Akira” adaptation on hold indefinitely, sources tell Variety.

Sources indicate that after a brief delay, the studio has pulled the plug on production indefinitely for the classic anime adaptation, which was set to begin later this fall. “Thor: Ragnarok” helmer Taika Waititi was on board to direct, and the studio hopes when he is done with production on “Thor 4” that the film can get back into production.

Waititi was in the midst of meeting with young Japanese actors for “Akira’s” two lead roles. While the studio originally delayed production to give him time to find the right talent, budget concerns sent the film back into development.
