'Creative differences' caused Seth Grahame-Smith to bolt from director's chair of 'The Flash'

Seth Grahame-Smith has reportedly left his directing duties on Warner Bros' The Flash over "creative differences." The superhero film will star Ezra Miller in the titular role.

Grahame-Smith, the author and screenwriter of such works as Pride and Prejudice and Zombies and Abraham Lincoln: Vampire Hunter, was to have made his directorial debut on the project based on the iconic DC Entertainment scarlet-speedster superhero, said The Hollywood Reporter.

The project will retain Grahame-Smith's script, which he wrote working off of a treatment by Phil Lord and Christopher Miller, the Lego Movie duo who once were eyeing it as a possible directing vehicle.

The Flash already has a release date, March 16, 2018, and Miller is portraying the classic hero known as "the fastest man alive."

Miller's Flash, aka Barry Allen, was introduced in a cameo appearance in Batman v Superman: Dawn of Justice, and is now shooting The Justice League Part One, which will be released in the fall of 2017.

Grahame-Smith still remains involved in other Warners projects. He is a writer on the studio's Lego Batman Movie and is working on Beetlejuice 2.
