Hollywood legend Paul Newman has been described as one of the greatest actors of all time and a true humanitarian in tributes following his death at 83.

The blue-eyed star of hit films including Butch Cassidy and the Sundance Kid, died at his farmhouse near Westport, Connecticut, on Friday after a battle with cancer.

British director Sam Mendes, who worked with Newman on the 2002 film Road to Perdition, said it was "the highlight of my professional life".

Broadcaster Sir Michael Parkinson said the star will be remembered as "one of the very finest screen actors".

Robert Redford, who starred with Newman in Butch Cassidy and the Sundance Kid and The Sting, said: "I have lost a real friend. My life - and this country - is better for his being in it."

British actor Daniel Craig, who appeared alongside Newman in Road to Perdition, said: "He was one of the greatest screen actors of all time and a beautiful man.".

Robert Forrester, vice chairman of the charitable Newman's Own Foundation, said the star's "heart and soul were dedicated to helping make the world a better place for all".
