Acclaimed actor Keith Jefferson, known for his collaborations with director Quentin Tarantino in films like "Django Unchained," "The Hateful Eight," and "Once Upon a Time in Hollywood," has sadly passed away at the age of 53, said The Hollywood Reporter.

His representative, Nicole St. John, confirmed his death, which occurred on Thursday. The actor had disclosed his cancer diagnosis in August.

In August, Keith Jefferson shared a message on his condition, stating, "Every now and then, God will give you a challenge and leave it up to you to fix it. When I was first diagnosed with cancer, I had to stop, pause and didn't want to share with anyone. Not my family nor extended family. Today, I'm finally at a place to share because my faith is getting stronger."

Keith Jefferson's Career

He emphasized that the learning process never stops, even for experienced actors like himself.

Keith Jefferson's final role will be in Jamie Foxx's latest film, "The Burial," where he starred alongside Tommy Lee Jones, Jurnee Smollett, and Alan Ruck.
