It seems that old dogs like the Expendables movies from Lionsgate can still learn new tricks, or at least bring in some fresh blood. The surprisingly long-running series has seen its fair share of veteran actors over its 10+ year history, which many would agree is arguably the franchise's biggest draw. Sylvester Stallone, Arnold Schwarzenegger, and Jason Statham have all enjoyed that limelight over the years, and things look to be about the same for the upcoming 4th chapter. But now, somebody new is joining the star-studded cast, and he might give the seasoned action heroes a run for their money.
