Ben Affleck Reveals the Main Villain in His Upcoming Batman Movie [UPDATE]

UPDATE: It has been reported that Deathstroke will be the main villain in Ben Affleck's standalone Batman movie. The Wrap states that a source "with knowledge of the situation" has confirmed the news to them. Original story below:

Batman star Ben Affleck has posted a mysterious new video on Facebook that shows footage of the DC villain Deathstroke. The actor provided no further information about the clip, which was filmed from a monitor, but you can check it out right here:

Affleck is currently working on the DC superhero team-up Justice League, which is released next year. In addition, he is set to direct and star in a standalone Batman movie for the studio further down the line. It is unknown if this Deathstroke footage is from Justice League, a test for the Batman film, or if Affleck is simply having some mischievous fun.

Deathstroke first appeared in a 1980 issue of The New Teen Titans, and the armored mercenary has gone on to appear in a wide variety of DC comics over the years. He is associated with Batman, and is a main adversary to the Green Arrow. On TV, he recently appeared in Season 2 of the CW show Arrow, played by Manu Bennett. He also featured prominently in last year's Batman: Arkham Knight.

This is the second time in recent weeks that one of Justice League's stars has teased fans. Earlier this month, Superman star Henry Cavill posted an image which seemed to suggest that he might wear the distinctive black suit from the The Death and Return of Superman comic books from the early '90s in the movie.

Justice League hits theaters on November 17, 2017, and also stars Gal Gadot, Jason Momoa, Ezra Miller, Ray Fisher, JK Simmons, Willem Dafoe, and Amber Heard.
