Hmmmmmm, Well a lot of people if you ask me. Living or all-time around ones which may no longer be around?, That's a good question.
A lot; The Godfather I & II (although, I hated that infamous horse scene, The most), Rainman, My Cousin Vinny, Hotel Rwanda, Rocky I & II, The Sting, Full Metal Jacket, Good Fellas, The Dark Knight for example.
Hmmmm, So many. The ones who made positive impacts on life most likely. It all depends whether you're talking about a relative, friend, someone famous????.
