The Justice League creative team has added an Oscar-winning filmmaker to its ranks. Ben Affleck will serve as an executive producer on the superhero movie in addition to playing Batman/Bruce Wayne, a Warner Bros. spokesperson confirmed to EW.

In his new behind-the-scenes role, Affleck will work with director Zack Snyder and screenwriter Chris Terrio to craft the story and see it through to the big screen. Production is currently underway.

The move further solidifies Affleck’s standing as one of the main architects of Warner Bros’. burgeoning movie universe based on DC Comics characters. He first took up the Dark Knight’s mantle in Batman v. Superman: Dawn of Justice, he has a cameo in Suicide Squad, and he’s set to write, direct, and star in a standalone Batman movie.

Affleck’s previous filmmaking credits include Argo, which won the Oscar for best picture; The Town; and Gone Baby Gone.

Though the DC Extended Universe got off to an uneven start with Batman v. Superman — which received disappointing reviews but has grossed $864 million at the worldwide box office — Warner Bros. has big plans for the franchise, including standalone Wonder Woman, Aquaman, and Flash movies and a second Justice League installment.

Justice League Part One is scheduled to open Nov. 17, 2017.

Deadline first reported the news about Affleck.
