Grahame-Smith was poised to make his feature directorial debut with the superhero film, which will star Ezra Miller as speedster Barry Allen. Warner Bros. is said to be pleased with Grahame-Smith’s script, but ultimately wanted a more experienced filmmaker guiding the production.
Warner Bros. isn’t eager to take a big risk in the wake of fan backlash to Zack Snyder‘s “Batman v Superman: Dawn of Justice.” Many comic book fans have called for Snyder to be replaced on WB’s two “Justice League” movies, but with production already under way, that isn’t happening.
