Flash already has a release date – March 3, 2018 – and an actor who portrays the classic hero known as "the fastest man alive" – Ezra Miller. Miller’s Flash, aka. Barry Allen, is due to be introduced in Batman v Superman: Dawn of Justice, and then more prominently in Justice League Part 1, which will be released in the summer of 2017.

Charles Roven is producing the movie. Deborah and Zack Snyder are executive producing.

Grahame-Smith is the author of such genre mash-up best-sellers as Abraham Lincoln: Vampire Hunter and Pride and Prejudice and Zombies. But he also also made a name for himself as a screenwriter, especially at Warners, where he is writing Lego Batman.
