Ben Affleck is taking a more hands-on role in the Justice League film -- specifically, as an executive producer. Deadline reports that in his new capacity as an executive producer, Affleck will be working with both screenwriter Chris Terrio and director Zack Snyder behind-the-scenes on the project. That's on top of his starring role in the film as Batman. Affleck has gained critical acclaim and accolades for his writing and directing work before in films like Gone Baby Gone and Argo, so it only makes sense to tap his advice.
