Dwayne "The Rock" Johnson has signed on to play one of the earliest superheroes: Doc Savage, who's said to be an inspiration for Superman. A film adaptation of Doc Savage was announced back in 2013, but apparently it's only now getting off the ground. Shane Black, the beloved action movie writer and director of Iron Man 3, is on board to direct.
There aren't many details about the film yet, but Johnson makes it sound like it should be pretty funny and strange. This is what he wrote in an Instagram post announcing the casting (emphasis his): "Here's the #1 reason I'm excited to become Doc Savage... HE'S A F*CKING HILARIOUS WEIRDO!"
