DC Entertainment president and chief creative officer Geoff Johns confirmed the casting to the Wall Street Journal, with Joe then tweeting about his new casting.

Ben teased test footage of Deathstroke on Twitter last month, leading to a flurry of speculation online about when and where Batman might duel the famed villain.

Geoff, who is co-writing Batman with Ben, declined to comment on whether Deathstroke would appear in Zack Snyder's Justice League, which is currently in production.

Ben's Batman reboot does not currently have a release date.
