Ben Affleck brought us what appears to be tangible evidence as to Deathstroke's arrival in the DC Extended Universe. Affleck has just posted, out of nowhere, footage to his official social media accounts of what looks like filming for a scene involving the legendary DC Comics assassin (and star of his own brand new comic!) Deathstroke walking down some sort massive aircraft bay.

Deathstroke is seemingly in the hangar of the Flying Fox, the large aircraft Batman uses as the Justice League's base of operations in Justice League.
After Affleck posted the footage, The Wrap is now reporting that Deathstroke is the primary villain of the solo Batman movie. While we're still unsure if this is test footage for that film or if Deathstroke may also be making a cameo appearance in Justice League, at least we now know where to expect Deathstroke's arrival in the DCEU.
So Ben Affleck maybe just revealed the arrival of a big DC Comics character to the movieverse out of nowhere by posting off-camera filming footage to Twitter. What a world we live in.
