Mickey Knox, the actor who inspired Woody Harrelson's character in Natural Born Killers, has died, aged 92. The former blacklisted star, who was novelist Norman Mailer's onetime brother-in-law, appeared in films like Knock on Any Door, The Godfather: Part III, and I Walk Alone. He also served as the English dialogue writer on two classic Sergio Leone spaghetti Westerns: Once Upon a Time in the West and The Good, The Bad & The Ugly. Knox was blacklisted during the McCarthy era of the late 1950s. He moved to Europe to become a screenplay translator. Actor Eli Wallach, who starred in The Good, The Bad and The Ugly, convinced director Leone to use Knox as a translator on the set. In 2004, he penned the memoir The Good, the Bad and the Dolce Vita: The Adventures of an Actor in Hollywood, Paris and Rome. Mailer supplied the introduction. Knox died on 15 November (13).
