While I like Cool Hand Luke, I also always remember the fight scene in Butch Cassidy and the Sundance Kid when they vie for leadership of the gang. There's no honor among thieves and it was definitely a low blow. Then "Think you used enough dynamite there Butch?" Plus don't forget the Sting and The Hustler.
He will be missed and like Kerry said, he was a class act. None of the over the top crap you get from movie stars today. Had a great marriage, was a humanitarian, donated all the proceeds from the Paul Newman line of food products to charities and sponsored the Hole In The Wall kids camps. Sponsors race drivers and did all of this without doing all the attention grabbing, over the top crap we see coming from the stars of today.
