From a New York Times obit by Clyde Haberman headlined “James Caan, Actor Who Won Fame in ‘The Godfather,’ Dies at 82”:

James Caan, who built a durable film career in varied roles across six decades but was forever identified most closely with one of his earliest characters, the quick-tempered, skirt-chasing Sonny Corleone in the original “Godfather” movie, died on Wednesday.

By the time “The Godfather” was released in 1972, Mr. Caan had established himself as a young actor worth keeping an eye on. He had a meaty role in “El Dorado,” a 1966 western that starred John Wayne and Robert Mitchum. (Wayne, Mr. Caan said, cheated at chess games during breaks in the filming.)
