In the film, Johnson will play the rival of Shazam, also known as Captain Marvel. The film is just now being written.

“We love Dwayne and have had nothing but success with him over the years,” Toby Emmerich, President and COO of New Line, told Variety. “When I look at Dwayne both off screen and on screen, he is such a larger than life character and it just made perfect sense to me that we put him in a DC comic movie. You look at these comic book characters and they have this certain swag and charisma that Dwayne carries with him where ever he is so that’s why this always made sense.”
