I admire Morgan Freeman. He has that kind of gentlemanly demeanour, really kind and polite. The type of character he plays are like the mentor or sidekick type, kind and helpful. It's no wonder that he is one of the perfect choices to cast as God in Bruce Almighty and as the mentor in The Shawshank Redemption and Se7en.
I was familiar with him way before I even knew it was him. He was one of the narrators of The Electric Company, narrating all sorts of educational stories.
His demeanour is the type you wish you had for a grandfather, someone who is kind, doting and likable.
