Dwayne "The Rock" Johnson will play the title role in director Shane Black's Doc Savage film.

The Fast and Furious actor confirmed via Instagram he'll be playing Clark "Doc" Savage in the film written by The Nice Guys writer Antony Bagarozzi and Jekyll writer Chuck Mondry. The crew met with Johnson this weekend to collaborate on the "very cool project."

Johnson also laid out some history on the character, writing that Doc Savage was the original inspiration for Superman. "First name Clark, called 'Man of Bronze,' retreats to his 'Fortress of Solitude' in the Arctic," he wrote. "Doc was physically and mentally trained from birth by his father and a team of scientists to become the perfect human specimen."

But the number one reason John is excited to play Doc Savage is because he's a "f--king hilarious weirdo."

Black had been eyeing Johnson for the role, the director said in March. "I made the decision that Dwayne is the guy," Black said. "It's on the back burner while he's busy."

Doc Savage has been in the works for a while, but no release date has been announced.
