Dwayne The Rock Johnson told MTV that he has been approached to appear in the upcoming Shazam film. Problem is, he can't decide if wants to play the good guy or the bad guy.

The Rock has asked MTV fans to help him decide whether he should play Captain Marvel or the film's villain Black Adam. The former wrestler stated, "Shazam, of course, I would love to play. They approached me about [Captain Marvel] and [villain] Black Adam as well. We've been meeting for months. We're toying with either one. I think it's up to the fans. Without question."

He continued, saying, "We went to Comic-Con a couple of months ago, and after coming back, we came to the conclusion that this particular role is not up to me, not up to Pete, and not up to the studio. I think it's up to the fans, very specifically because they are passionate about the comic book, about the history and mythology [of the character]. They will be very vocal."
