While Warner Bros. has no firm plans on a solo Batman movie starring Ben Affleck, the Oscar winner has already written a script for one.

In an interview with The Hollywood Reporter, William Morris Endeavor co-CEO Patrick Whitesell said that Affleck, one of the agency’s clients, is signed on for at least two more DC Comics movies. Whitesell also dropped an interesting tidbit:

“He’s contracted to do at least Justice League One and Two, so at least three times wearing the cape… There’s a script that he’s written that is a really cool [Batman] idea, so that’s out there as an option.”

There has been no shortage of rumors surrounding a possible Batman movie for Affleck. During Comic-Con 2015, Deadline reported that Affleck was working closely with DC Chief Creative Officer Geoff Johns on a script.

Affleck will also make a cameo as the caped Crusader in August’s Suicide Squad. He made his debut in the role in Batman v Superman: Dawn of Justice.
