Well, that was easier than I thought it would be! Yes, the movie was The Green Mile, based on the book by Stephen King.
The part of John Coffey was played by Michael Clarke Duncan, who was nominated for Best Supporting Actor (but didn't win). He was so delighted to be recognized on the street, he'd give $5.00 to each person who could call him by all 3 names.
One of my favorite quotes by John Coffey:
Paul Edgecomb: On the day of my judgment, when I stand before God, and He asks me why did I kill one of his true miracles, what am I gonna say? That is was my job? My job?
John Coffey: You tell God the Father it was a kindness you done. I know you hurtin' and worryin', I can feel it on you, but you oughta quit on it now. Because I want it over and done. I do. I'm tired, boss. Tired of bein' on the road, lonely as a sparrow in the rain. Tired of not ever having me a buddy to be with, or tell me where we's coming from or going to, or why. Mostly I'm tired of people being ugly to each other. I'm tired of all the pain I feel and hear in the world everyday. There's too much of it. It's like pieces of glass in my head all the time. Can you understand?
Paul Edgecomb: Yes, John. I think I can.
New question on Saturday!
