I loves me some Doc Savage, but I've never had the stomach to watch the 1970s movie with Ron Ely. But now Sam Raimi apparently has the rights, along with the Shadow and the Avenger and possibly several other pulp characters, and that Sam Raimi kinda has this superhero movie thing figured out.
Now I have previously suggested that Daniel Cudmore [Colossus] would be good for a youngish Doc, being a great big square-jawed guy . . . but y'know, Dwayne Johnson is great. He's funny, he can obviously do action, and the camera loves him. And the man needs a franchise. And Doc Savage is potentially a great franchise.
