He has long since proven his “legendary” credentials and I say give him a shot in Expendables Part 3.
Personally, I’d love to see him play the villain; someone who is a trigger happy psychopath and have him in some serious hand to hand combat. He played a (sort of) villain in Doom and was the best thing about the film.
Johnson has great screen presence and is an excellent actor to boot; he also has a huge fan base and can increase the box office by having someone the younger audience will be interested in seeing.
Sly himself has said he wants to have a few younger action stars in Part 3 as a sort of passing of the torch and to me this is the perfect opportunity to bring in The Rock.
Let’s not forget this:
He has said so himself that he wants to be Expendables, so come on Sly; Bring in the big guns and have Dwayne Johnson put boots to asses!
