Poor man's Frank Grillo?
Seriously, DC is always seemingly playing catch-up with Marvel.
Manganiello looks like Frank Grillo's lost brother and conceptually, Deathstroke isn't that far from Crossbones.
We'll see how it goes, but for a main villain, they should have chosen a better actor. Even under the mask. It comes through as was visible in V for Vendetta and The Dark Knight Rises.
Laura:You left a dead prostitute buried alone in the desert?
Kyle:She's not alone.
