John Barrowman, Nathan Fillion, and Stephen Amell. They're in shows that I like, and outside of the screen, they seem to be good people that interact with their fans and have good opinions on various topics.
keanu reeves. because he is so down to earth, lives in a simple appartment, takes the subway and gives away most of his money with the explanation "I already have enough, I don't need more". that is a truly admirable way of living and i think the world would be a better place if people were less greedy. cheers
