It seems that Deathstroke has already been found for the new Batman film and it is Joe Manganiello.
Recently Ben Affleck teased the world with a video of DC villain Deathstroke, but now it appears we know it was Joe Manganiello doing a costume test and he is set to appear in the solo Batman film. No one is commenting on whether he may pop up in the Justice League film that is currently filming, but something tells me he will make a cameo.
The standalone Batman film is currently being written by Ben Affleck and Geoff Johns, but no firm release date has been announced for the film as of yet. There is a lot of speculation that it will be 2018, but that is pure speculation at this point.
As for the casting of Manganiello in the role… I love it. I think he’s a perfect fit for the character and he is probably the most spot-on casting that has happened in the DC films yet. I’m all for it.
