I dont think hes the best but Edward Norton is really under rated in my opinion in American History x he was immense along with Red Dragon with Hopkins what a movie although i prefer the original Manhunter
And im sure the guy who played morse is David Jason hes also in only fools and horses
it has to be David Jason, The guy is a legend, how many actors can go from being Del Boy to DI Frost and dont forget Open All Hours and The Darling Buds Of May. No one else is that versatile
Russell Crowe, Al Pacino, Robert De Niro, Michael Gambon, Edward Norton, Christian Bale, Sir Anthony Hopkins, Kevin Spacey, Jim Carrey.. there's just so many
