MEXICO CITY (AP) — Dwayne “The Rock” Johnson says he will play a role in an upcoming DC Comics movie adaption but has yet to decide between superhero Shazam and his arch-nemesis Black Adam.

He may not have a hard time making a decision. He told The Associated Press on Monday that he has always been a fan of anti-heroes and said one of his favorite DC Comics characters is Black Adam.

Appearing in Mexico City to promote “Hercules,” Johnson said he will make sure comic fans are not disappointed.

“I am putting my heart and soul and my bones into this role,” he said.

Johnson didn’t say whether his character will appear in the film “Superman v Batman: Dawn of Justice,” which is scheduled to be released in 2016.
