This is for Fox so it's dedinately not canon. It will probably be a co-production between Fox Animation and a third-party studio.
Quote:
Fox/Disney has attached Thor: Ragnarok director Taika Waititi to “crack” Flash Gordon, as an animated feature film. John Davis is producing. I had heard that the inventive filmmaker Waititi was signing on to write and direct, but his camp indicates it’s too early to gauge exactly what his role would be.
