Disappointing news Flash fans. Seth Grahame-Smith, The Flash standalone film’s director, has left the project due to “creative differences,” reports THR. However, there remains a sliver of hope in that the film is reportedly maintaining Grahame-Smith’s script, which was a treatment from Phil Lord and Christopher Miller, the pair known for the Lego Movie.

The Flash standalone was supposed to be the writer’s directorial debut. Grahame-Smith, known for such works as Abraham Lincoln: Vampire Hunter and Pride, Prejudice, and Zombies is still involved in plenty of other Warner Bros. projects, namely Lego Batman Movie and Beetlejuice 2.

It’s incredibly unfortunate news, since recently rumors suggested the film has begun casting. The alleged characters being eyed could provide the perfect set-up for the Scarlet Speedster’s solo outing. Because the former director’s script will still be used, unless things change, those rumors may hold true.

The film will not release until the spring of 2018, so Warner Bros. has plenty of time to get a suitable replacement. But it would be nice to know what those creative differences were, espcially considering a new report suggests Ben Affleck and Geoff Johns will have complete creative control of the solo Batman movie.

The Flash, starring Ezra Miller as Barry Allan’s Flash, is slated to hit theaters on March 3, 2018.
