7. Arnold Schwarzenegger

The Governator has shown that you can’t count him out of action flicks yet with his string of recent movies. You can already see how he’s got that big-guy, flat-top look down pat in Terminator: Genisys, and of course we shouldn’t have to mention that he’s both already sported the bionic eye and metal arm look, as well as travelled through time. Deadpool would have some fun breaking the fourth wall with that meta-humor.
