Kick Ass 2

Would you have expected anybody else? He was also in the 1st movie, playing the exact same character that becomes the Motherf'ucker, Red Mist. They'd be a little crazy to change up the cast of the original characters to the sequel, since you would then have people arguing over the acting quality of the original actor vs the new one.

I don't know anything about the comics at all, therefore did not know his name would change to The Motherfucker. Have forgiveness for a plebeian nerd.
