The Hollywood Reporter has learned that Seth Grahame-Smith, the author of "Abraham Lincoln: Vampire Hunter" and "Pride and Prejudice and Zombies," is in negotiations to write and direct Warner Bros. upcoming "Flash" solo film.

The report comes from undisclosed sources, who state that the author will come on board following the departure of Phil Lord and Christopher Miller. That duo, who worked up a treatment for the film and were expecting to direct it as well, left the project to work on the upcoming Han Solo prequel.

While "The Flash" would be Grahame-Smith's directorial debut, he already has practice writing superheroes for the big screen; he's the screenwriter behind the upcoming "LEGO Batman" film. He's also directed for television before, helming a few episodes of his MTV series "The Hard Times of RJ Berger."

"The Flash" already has a leading man in place, Ezra Miller, who is expected to make an appearance in next year's "Batman v Superman: Dawn of Justice" and 2017's "Justice League" film. The solo "Flash" film opens on March 23, 2018.
