The DC Extended Universe is truly a fascinating place. While the MCU has become a well-oiled machine over the past decade of filmmaking, the DCEU is still very much in its infancy. Projects are both announced and cancelled, directors have fallen, and the overall future of the shared universe is a mystery to the general public. The most recent installment was Justice League, which brought the heroes together, while also uniting Lex Luthor and Deathstoke during its post-credits scene. The latter is played by Joe Manganiello, and was originally slated to make his grand debut in Matt Reeves' Batman movie. Now it looks like Deathstroke is still part of the DCEU, but could have a role in an entirely different franchise.
