Ben Affleck ei koskaan saanut sitä omaa Batman-elokuvaansa, mutta vuodettujen tietojen perusteella projekti vaikutti mielenkiintoiselta. Zack Snyderin Full Circle Justice Leaguessa Affleck kertoi enemmän ajatuksistaan ja ideoistaan. Muun muassa Deathstroke olisi ollut mukana isosti pahiksena, ja roolissa piti olla Joe Manganiello.
"There were a number of them that I was kind of exploring, and, the plans were to make interesting, nuanced, complex characters, in particular to the character you mentioned. I kind of feel like either you do - I'm just going to get into my own preference here - but either you do a kind of massive one villain that is so formidable you just can't imagine how your protagonist is going to be able to overcome it. Or you have to really sort of populate kind of, you know, Injustice - these big group villains - where you have to get all these different characters."
"So I was at the time really trying to hone in and focus on that character and get into depth and detail about it to make him seem as impressive as I felt there was the opportunity to do. That's the only detail I have for you."
"It was a really dark story in which Deathstroke was like a shark or a horror movie villain that was dismantling Bruce's life from the inside out. It was this systemic thing: He killed everyone close to Bruce and destroyed his life to try and make him suffer because he felt that Bruce was responsible for something that happened to him."
