Back in April, we reported that the extremely busy filmmaking duo of Phil Lord and Chris Miller have been set to write a story treatment for Warner Bros.' The Flash. It was believed that the filmmakers would come aboard to direct, but back in July, they signed on to direct Star Wars Anthology: Han Solo Movie for LucasFilm. Today, The Hollywood Reporter has word that Seth Grahame-Smith has signed on to write and direct The Flash.

Ezra Miller has been attached to star ever since Warner Bros. announced their massive superhero movie slate last October. Back in May, Phil Lord revealed that their story will likely focus on Barry Allen, and that it will be separate from The Flash TV series, which stars Grant Gustin as Barry Allen. There have been rumors that The Flash and the rest of the Justice League members will be introduced at the end of next year's Batman v Superman: Dawn of Justice, but that has never been confirmed.

Charles Roven will produce The Flash, with Batman v Superman director Zack Snyder serving as an executive producer alongside his wife, Deborah Snyder. The movie has already been given a March 23, 2018 release date by Warner Bros., putting it up against 20th Century Fox's Anubis and an untitled 20th Century Fox/DreamWorks Animation sequel. It isn't known when production will actually begin quite yet.

Ezra Miller's Barry Allen will also appear in Justice League Part 1, which has been set for release on November 11, 2017. After The Flash debuts in the spring of 2018, he will most likely return in Justice League Part 2, set for release on June 14, 2019. No story details have been given for The Flash yet, since there is very little we know abut the treatment that Seth Grahame-Smith will work from.

The Flash will mark Seth Grahame-Smith's feature directorial debut, although he has directed two episodes of the MTV comedy series The Hard Times of RJ Berger, which he co-created with David Katzenberg. He has written several screenplays including Abraham Lincoln: Vampire Hunter, based on his own novel, Dark Shadows and the upcoming Beetlejuice 2. He is also writing the script for Warner Bros.' The LEGO Batman Movie, arriving in theater February 10, 2017.
