Bill Dubuque wrote the script, which follows a mild-mannered accountant who moonlights as a deadly assassin.
Gavin O’Connor (“Warrior”) is circling the director’s chair, though there is no deal in place yet. Will Smith was previously attached to star, as Warner Bros. has long believed the project to be worthy of an A-list actor.
After doing press for “Gone Girl,” Affleck will finish filming “Batman v Superman: Dawn of Justice” for Warner Bros. and he hopes to shoot “The Accountant” before embarking on his next directorial effort, WB’s “Live By Night.”
Affleck is represented by WME, and a representative for the actor did not immediately respond to a request for comment.
The news was first reported by Variety.
