Night is Affleck’s adaptation of the Dennis Lahane crime novel set during Prohibition that is due to go before cameras in November.

Warners had no comment.

That Affleck was to direct a Batman stand-alone movie isn’t new. The actor made that a condition when he signed on to act as Bruce Wayne/Batman in 2013.

And while Warners' slate of movies based on DC characters was missing a stand-alone Batman movie, the studio always planned for one (or more) to be in the works to complement a schedule that included lesser-known heroes.

Affleck is also expected to appear in the studio's Justice League movies
