Mark Ruffalo is easily one of my favourite male actors working today and his roles have been incredibly varied, including his two recent leading roles in The Normal Heart and Begin Again - both of which prove that he can easily hold a film and should continue to do so in future.
I've only one note on this list...I should see You Can Count on Me. Otherwise enjoy.
