And now a new rumor has surfaced that claims Reeves has someone in mind to take over the role of the Caped Crusader if Affleck decides to step down - and the new contender was actually a candidate for the role before Christian Bale was cast in Batman Begins.
Affleck has gone as far as say that he's "contemplating" appearing in 2018 Matt Reeves-directed film "The Batman".
Director and film critic John Campea revealed the news on his popular YouTube show, saying: "I'm hesitant to say anything, but I talked to a Hollywood producer yesterday who told me who Matt Reeves wants as Batman". It has become clear that I can not do both jobs to the level they require. Jason Momoa, who plays Aquaman in Justice League, was also called into question for making a rape joke back in 2011. "And, I've got to be honest with you, that name caught me a little bit by surprise". His successor? Jake Gyllenhaal, who has allegedly been shortlisted to headline The Batman - and, by effect, a whole new trilogy - under the stewardship of Matt Reeves. "It doesn't mean anything's going to happen".
In other words: As "Justice League" opens Friday, could this signal Affleck's exit from DC's cinematic universe? His Batman was angry and misguided in Batman v Superman, but at least there was something going on with him.
Shortly after publicly condemning movie mogul Harvey Weinstein's behaviour - Affleck worked on several films with Weinstein early in his career - he was accused of groping an actor on live TV in 2003. The guy tried his best, and it didn't work.
With Justice League nearly upon us, Affleck has recently stated that he's "contemplating" whether to return for The Batman, which is now being directed by War for the Planet of the Apes helmer Matt Reeves. "We could use more women".
Talking about Justice League, Affleck said, "We certainly are in need of heroes in 2017".
