AIt is unknown at this time, however the latest comment from Zack Snyder does seem to strongly imply that Henry Cavill will play Superman in the Justice League. While talking to the New York Post in November of 2012, Man of Steel director Zack Snyder had this to say on the subject: "I don't know how Justice League is going to be handled. Honestly, I dont. But the Man of Steel exists, and Superman is in it. I don't know how you'd move forward without acknowledging that," he explained. When pressed a little further about it, and whether or not WB has asked him to include Man Of Steel into a larger universe, Snyder said, "I can't really say anything to that, because that's a big spoiler. I will say, yeah, they trust me to keep them on course." Zack Snyder's comment on the subject earlier this year, while more vague than the most recent one, also strongly hinted that if Man of Steel is a success, it could very well lead into a Justice League movie. "We know that Superman is the jewel in the DC crown and really what we're trying to do is get his house in order, and then, who knows what's possible." - Zack Snyder answers a question about whether or not we will see his Superman leading into a Justice League movie, at the San Diego Comic-Con, July 2012.
