On the heels of the news that Warner Bros are shelving, once again, the Akira live-action adaptation news broke through The Hollywood Reporter that Taiki Waititi was returning to Marvel Studios to director Thor 4. Thor 4 follows up his hugely successful Thor: Ragnarok, Waititi had to take a step away from MCU duty in order to work on the then-upcoming Akira which was scheduled for a May 2021 release.
It is being rumoured like now that Akira is being pushed back until after Thor 4 is completed, due to Warner Bros being somewhat uncomfortable with the dates of the two projects being too close. Expect more news in regards to Thor 4 this coming SDCC!
