As the DC Extended Universe continues to expand on screen with this summer's Suicide Squad, future projects are in production and development leading up to the highly anticipated Justice League ensemble films. But, as Warner Bros. has made certain alterations following the DCEU launch with Batman V Superman: Dawn of Justice, changes are in store for the studio's big screen take on The Flash.

Already set for release in March of 2018, Warner Bros. had previously announced a writer/director and star of The Flash film. However, though Ezra Miller debuted as Barry Allen in a cameo role during Batman V Superman, and will carry the role through the Justice League films, the future of the director's chair is more uncertain.

THR is reporting that director Seth Grahame-Smith has left his position on the production, citing "creative differences" for his departure. While Grahame-Smith is still working on two other productions under the Warner Bros. umbrella, it seems as though plans for the film didn't quite line up to the director's vision.

Following Grahame-Smith's exit, it's possible the studio will move forward quickly in the search for his replacement on the film. While there aren't any details on the specifics, and neither Warner Bros. nor DC has confirmed the news, it's likely set in stone and fans can expect the project to move forward with a new director.

Grahame-Smith is fairly well-known for his work as an author, taking traditional stories and putting a comedic horror-inspired spin on them, leading his past work -- which includes Pride & Prejudice & Zombies, as well as Abraham Lincoln: Vampire Hunter -- straight to the big screen. While the up-and-comer might not be sticking around to occupy the director's chair, the film will retain Grahame-Smith's script, which was based on a treatment by Phil Lord and Christopher Miller. Speaking of Lord and Miller, Grahame-Smith's other WB projects still moving forward include the LEGO Batman Movie as well as the other project in which he's involved, Beetlejuice 2.

Grahame-Smith's exit comes as no surprise in the developing DCEU, which saw the original director of Wonder Woman leave before Patty Jenkins stepped in. Elsewhere in superhero film franchises, while Ant-Man was in development, director Edgar Wright left the project over creative differences. Regardless, the film still went on to be fairly well-received under the hand of Peyton Reed, and the character will continue to appear throughout the Marvel Cinematic Universe.

In terms of The Flash's future, Lord and Miller were originally looking at the film as a directing vehicle, and other directors may jump at the chance to join the DCEU. Needless to say, finding a replacement might not be a very long process, and no changes in the film's schedule have been announced as of yet.
