According to Hollywood entertainment website, Variety, Waititi is also directing the upcoming Thor 4 movie, and that the production schedules for it and Akira overlapped.
Leonardo diCaprio and Thor: Ragnarok director Taika Waititi are co-producing the upcoming live-action Akira film.
Warner Bros. was caught unaware of Waititi’s decision to postpone and says they hope that the director would resume his work after Thor 4’s filming.
Unfortunately, it looks like that film is going to be delayed indefinitely.
