Well, this is a little unexpected…
While it was known that Phil Lord and Christopher Miller (they of The Lego Movie and 21 Jump Street) were writing a treatment for the Ezra Miller starring Flash feature film, once they had signed on for one of the “Stars Wars Story” films, WB was left to look for someone else to fill their shoes.
According to The Hollywood Reporter, the studio has landed on author Seth Grahame-Smith to both write and direct the big screen version of Barry Allen’s adventures. Grahame-Smith is best known as the author of the literary smash-up hits like Pride and Prejudice and Zombies and Abraham Lincoln, Vampire Hunter. The latter having already been adapted into a film, and the former getting its own cinematic take next year.
The author is already cracking away at another DC-based property, as he’s the screenwriter for the upcoming Lego Batman spin-off, so it’s easy to see how the folks at WB connected the dots from Lord & Miller to here.
Much like the upcoming Deadpool, this will be another first time director manning a big budget superhero tentpole. Though one has to wonder the amount of oversight that will entail, my guess is a lot. The Flash is expected in early 2018.
