Dwayne Johnson is absurd.That’s not an insult. It’s just that there’s never been anyone quite like him in pop culture. How many pro wrestlers became successful actors? Andre the Giant? Hell, how many athletes have become leading men? O.J. Simpson? How many put together lasting careers? The only name remaining is Arnold Schwarzenegger.Schwarzenegger’s a living legend, but somehow the comparison seems apt: Based on data from The Numbers, Schwarzenegger has been a leading actor in 25 films grossing about $4 billion worldwide, while Johnson has been a lead in 17 films grossing a cumulative $3.7 billion worldwide.But we’ve had Arnie since the early 1980s.
