“Oh Luke, You Wild, Beautiful Thing. You Crazy Handful of Nothin'.”

Paul Newman, one of the last of the great 20th-century movie stars, died Friday at his home in Westport, Conn. He was 83.

The cause was cancer, said Jeff Sanderson of Chasen & Company, Mr. Newman’s publicists. …

He acted in more than 65 movies over more than 50 years, drawing on a physical grace, unassuming intelligence and good humor that made it all seem effortless.

Yet he was also an ambitious, intellectual actor and a passionate student of his craft, and he achieved what most of his peers find impossible: remaining a major star into a craggy, charismatic old age even as he redefined himself as more than Hollywood star. He raced cars, opened summer camps for ailing children and became a nonprofit entrepreneur with a line of foods that put his picture on supermarket shelves around the world. …

Mr. Newman’s filmography was a cavalcade of flawed heroes and winning antiheroes stretching over decades. In 1958 he was a drifting confidence man determined to marry a Southern belle in an adaptation of “The Long, Hot Summer.” In 1982, in “The Verdict,” he was a washed-up alcoholic lawyer who finds a chance to redeem himself in a medical malpractice case. …

Few major American stars have chosen to play so many imperfect men. …

“When a role is right for him, he’s peerless,” the film critic Pauline Kael wrote in 1977. “Newman is most comfortable in a role when it isn’t scaled heroically; even when he plays a bastard, he’s not a big bastard — only a callow, selfish one, like Hud. He can play what he’s not — a dumb lout. But you don’t believe it when he plays someone perverse or vicious, and the older he gets and the better you know him, the less you believe it. His likableness is infectious; nobody should ever be asked not to like Paul Newman.” …

Mr. Newman’s last screen credit was as the narrator of Bill Haney’s documentary The Price of Sugar, released this year. By then he had all but announced that he was through with acting.

“I’m not able to work anymore as an actor at the level I would want to,” Mr. Newman said last year on the ABC program Good Morning America. “You start to lose your memory, your confidence, your invention. So that’s pretty much a closed book for me.”

But he remained fulfilled by his charitable work, saying it was his greatest legacy, particularly in giving ailing children a camp at which to play.

“We are such spendthrifts with our lives,” Mr. Newman once told a reporter. “The trick of living is to slip on and off the planet with the least fuss you can muster. I’m not running for sainthood. I just happen to think that in life we need to be a little like the farmer, who puts back into the soil what he takes out.”

Now, I love Redford, and when he passes, that will be a sad day, too, but it won't be as sad as last Saturday. It'll be a long time before a day is as sad as that. Newman was one for the ages.
