The Crow reboot or remake, sometimes called The Crow Reborn, is something of a troubled production. The movie keeps losing stars, losing studios, and it's been in that development hell that some movies end up in. Jason Momoa was last in the lead role back in August 2016 and it looks like it might be getting off of the ground. Momoa and director Corin Hardy posted these pictures to instagram indicating that pre-production or maybe production have started on the movie.
We don't have any other casting announcements at this time but if this movie is finally getting off of the ground then we should get some soon. As for a release date if this is moving forward right now and they shoot this movie on the cheap it could be looking at a fall 2018 or sometime in 2019 release date. At least it'll finally get made one way or another.
