One of the key members of the Justice League just lost his boss. Seth Grahame-Smith, who wrote and was planning on directing The Flash solo movie slated for 2018, has left the project due to "creative differences". The Hollywood Reporter broke the news. No other details were given except that Grahame-Smith's script is still in play and, with a 16 March 2018 US release date, there's lots of time to get a new director.
In the film, The Flash will be played by Ezra Miller, who made his first appearance in last month's Batman v Superman: Dawn of Justice. He'll next appear in Justice League Part One, directed by Zack Snyder, before zooming into his own movie.
