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.

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 a star, Ezra Miller, who's portraying the classic hero known as "the fastest man alive." There is plenty of time for the studio to find a director.

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