This is a tough question to answer- a lot like the thread about the best football player..
Robert Duvall is a consummate actor- even in some of his more minor roles I sometimes find on cable... and there are a lot of other actors I could recite here but the one I always remember is Denzel Washington.. his role in "Man on Fire" cemented it for sure for me, but he has been in several others that I could watch over and over...
