Pleasantly surprised by him.
When I saw that Kellan was cast in the Expendables 3, I was a little bit apprehensive. After looking him up and seeing that his big break was in Twilight, I just really didn't figure that he'd be capable of pulling off being a badass.
That said, I recently watched the movie Arena. To me, it seemed like he did surprisingly well in an otherwise really crappy movie. He pulled off the capable badass persona pretty well, and he has a lot of intensity IMO.
Looking forward to seeing him in some other roles now; hopefully he does well!
Let a little insanity into your life.
