Did Ben Affleck Just Reveal 'Justice League' Villain?

— -- This could be for next year's "Justice League," or it could mean nothing, but Ben Affleck just released some serious footage on Twitter.

The silent 27-second clip features the famed DC villain Deathstroke.

Deathstroke is from the 1980s and is a pretty amazing foe. He's often the nemesis of both Batman and the Green Arrow, so that could also be a hint of a new Justice League member.

If you've seen "Arrow" on the CW, then you know a little about Slade Wilson, who possesses enhanced physical powers and serious combat skills. And if you know comics, you know Marvel's "Deadpool" also began as a spoof of Deathstroke, aka Wade Wilson, who is played by Ryan Reynolds onscreen.

Here's the clip. Enjoy!

Here's the first "Justice League" trailer from last month's Comic-Con.
