Once blacklisted actor Mickey Knox has died at the age of 91 in Los Angeles on Nov. 15, just a month shy of his birthday.

According to The Hollywood Reporter, Knox's daughter confirmed the news through Facebook.

Knox appeared in The Godfather: Part III where his character was shot up in a helicopter attack. He also was in Beyond the Law and Wild 90, which were directed by Norman Mailer. He also served as a dialogue writer for two of Sergio Leone's spaghetti Western films, including The Good, the Bad and the Ugly.

In a 1998 interview he discussed the dubbing work he did for the films. "I had to find out the right dialogue not only in terms of moving the story along, but also fit the lips. It's not an easy thing to do."

The actor was blacklisted towards the end of the McCarthy trials, which caused him to move to France and Italy, which is how he got to work on Leone's films.

WENN reports that Woody Harrelson's character in Natural Born Killers was inspired Knox.

In 2004, the actor wrote the memoir The Good, the Bad and the Dolce Vita: The Adventures of an Actor in Hollywood, Paris and Rome. Mailer, who was his brother-in-law for a time, wrote the introduction.
