The Hollywood Reporter:

[Taika] Waititi has inked a deal to write and direct a follow-up to his 2017 smash, Thor: Ragnarok.

But his boarding of what would be a fourth installment of the Marvel franchise comes at a cost: Warner Bros.' long-gestating adaptation of Japanese manga, Akira.

That project, which was penciled for a May 21, 2021 release and had Waititi testing actors in a worldwide search for talent, is being put on pause indefinitely as the two projects' production dates began to bump up against one another. Script development concerns caused Akira to push back its shooting start and while some of those have been addressed, say sources, the dates were now too close for comfort.

Warners' next step for Akira is unclear but the project now seems to be in flux. Several sources have said that Warners is keen on keeping Waititi involved for the long-term and hopes to see him pick up Akira after Thor 4.

Tremendous news. Akira is one of those projects that I feel is cursed to never be made (and maybe shouldn't be?), but Watiti's version of Thor is amazing, and begs to be explored further.

Guess this was supposed to be an announcement for Marvel's Hall H panel on Saturday at SDCC?
