Paul Newman was the last of a breed, a contemporary of James Dean.
Leonardo DiCaprio has just described him as a role model for the more socially-conscious Hollywood type. Those sauces he dreamed up have so far taken well over $200m for charities including the Hole in the Wall Camps for sick kids. Favorite films? The Hustler, Cool Hand Luke, Butch Cassidy - there are so many to chose from.
There's a well-written tribute to him here in the New York Times.
Here are some wonderful images of him on Youtube. And see him here in classic form in Cat on a Hot Tin Roof.
