All of De Niro's movies have some variety to offer. He was awesome in the movie ' Cape Fear'. "Heat' is prolly the one that I would be able to watch over and over again without getting bored . Pacino and De Niro are my equal favorites. Pacino has the best lines in most of his movie roles that will stick to your mind even after the movie itself has has faded to black and white. Nicholson is great too but not my favorite. I love Hackman. Hackman is a great actor though not so charismatic on the surface in the likes of Mel Gibsons league. Some memorable works of Hackman (according to me) include 'The Quick and the Dead','Enemy of the State', 'Heist' to name a few. Shall I add that I am waiting for a movie starring Gene Hackman and Hugh Jackman in fictitious movie called 'The Tongue Twisters'. Huu Haa!
