It looks like The Flash is in trouble as it was revealed a little earlier today that director Rick Famuyiwa has left the movie over creative differences with Warner Bros. Seth Grahame-Smith walked away from the project for the exact same reason, and it now appears as if this is going to cause a delay in both the start of production and the planned 2018 release date.

Since coming on board back in June, Famuyiwa has cast Kiersey Clemons and Billy Crudup in key roles, and even hired the costume designer from his breakout hit Dope to work on it.

The filmmaker issued a statement about his decision to leave The Flash, and while no specifics are revealed about those “creative differences,” The Hollywood Reporter reveal that his desire to make a movie with “more edge” clashes with what Warner Bros. is looking for.

“When I was approached by Warner Bros and DC about the possibility of directing The Flash, I was excited about the opportunity to enter this amazing world of characters that I loved growing up, and still do to this day. I was also excited to work with Ezra Miller, who is a phenomenal young actor. I pitched a version of the film in line with my voice, humor, and heart. While it’s disappointing that we couldn’t come together creatively on the project, I remain grateful for the opportunity. I will continue to look for opportunities to tell stories that speak to a fresh generational, topical, and multicultural point of view. I wish Warner Brothers, DC, Jon Berg, Geoff Johns, and Ezra Miller all the best as they continue their journey into the speed force.”

The hunt for a new director has now begin, but with star Ezra Miller committed to another project next July, we could be looking at significant delay now that shooting is unable to begin in March. That’s a shame, but after Batman v Superman: Dawn of Justice and Suicide Squad, the studio can’t afford to deliver another disappointment when The Flash is released.
