Ben Affleck posted a rather cool clip on Twitter this morning featuring The Terminator himself Deathstroke; I’d been wondering why they hadn’t brought him back to Arrow (thus making the show not very good) and now we know.
According to The Wrap Deathstroke will be the main antagonist in 2018’s The Batman.
The Wrap states Ben Affleck wasn’t just teasing: Deathstroke will, in fact, be the main antagonist of the Batman standalone movie he’s directing, TheWrap has exclusively learned from an individual with knowledge of the situation.
There is speculation that the actor behind the mask is Joe Manganiello (True Blood,Magic Mike).
