Curb Your Enthusiasm star Richard Lewis had died, with fellow actors issuing tributes to the 76-year-old.
The actor, writer and comedian enjoyed a distinguished Hollywood career and is best-known for his long-standing role in the US comedy.
He starred as a fictionalised version of himself in Curb Your Enthusiasm, which debuted back in 2000.
The actor returned for the show's 12th and final season, which began airing this year. He also starred in Robin Hood: Man in Tights, Daddy Dearest, Leaving Las Vegas and more.
His death comes soon after he announced he had been diagnosed with Parkinson's disease, which he confirmed in April 2023.
He stated at the time: "Luckily I got it late in life, and they say you progress very slowly if at all and I'm on the right meds and it's cool."

During a video he posted on X, formerly Twitter, he continued: "I just wanted you to know that that's where it's been at.
"I'm finished with standup, I'm just focusing on writing and acting. I have Parkinson's disease but I'm under a doctor's care and everything is cool and I love my wife, I love my little puppy dog and I love all of my friends and my fans."
It's been reported the actor suffered a heart attack. His publicist Jeff Abraham announced the news, with Deadline reporting that he announced: "His [Lewis'] wife, Joyce Lapinsky, thanks everyone for all the love, friendship and support and asks for privacy at this time."
