The Walking Dead star Scott Wilson has passed away. He was 76-years old. The actor had been battling cancer. His death was announced by the show's social media account. It was revealed over the weekend at NYCC that Wilson would reprise his role as Hershel Greene in season nine, though it is not clear how many episodes he will appear in. The actor had already filmed some of his scenes before his death. The announcement was made about an hour before the news of Wilson's death began to spread.

In addition to his work on AMC's The Walking Dead, Scott Wilson had over 50 film credits to his name, including In the Heat of the Night, In Cold Blood, The Great Gatsby, Dead Man Walking, and Pearl Harbor. Wilson also starred in CSI: Crime Scene Investigation as casino boss Sam Braun, as well Netflix's The OA as Abel Johnson. His role as Hershel Greene on The Walking Dead lasted for four seasons before the character was killed off. However, Wilson has made a few cameos on the show over the years.

Scott Wilson was born in Thomasville, Georgia in 1942. He starred in 1967's In Cold Blood at the age of 25 and portrayed real-life murderer Richard Hickock. His performance was widely praised and earned him the cover of Life magazine alongside In Cold Blood author Truman Capote and co-star Robert Blake. In a 2011 interview, Wilson reflected on his career, admitting that there have been dry spells over the years, but stated that he has always found work and that he loves acting and was striving to be the best actor that he could be.

A spokesman for AMC said that Scott Wilson "will always be remembered as a great actor." The spokesman went on to say that Scott's character on The Walking Dead, "lived at the emotional core of the show," which has been echoed by critics and fans of the show as well. In both the comics and the show, Wilson's Hershel Greene is initially introduced saving the life of Carl Grimes, the son of Rick after he is shot by one of Hershel's neighbors and becomes a part of the team.

The Walking Dead Season 9 premieres tonight on AMC, but it is not clear how or when Scott Wilson will appear in the show. However, it is believed that it will either be through hallucination or flashback since the Hershel Greene character is dead. In addition to Wilson, Jon Bernthal and Sonequa Martin-Green are also returning to the hit AMC series. Wilson was scheduled to appear at Walker Stalker Con in Atlanta in late October. The event brings together many of The Walking Dead's former and present cast members together. The news of Scott Wilson's death was first announced by The Walking Dead Twitter account. Rest in Peace, Scott Wilson.

I am utterly broken hearted to hear about the passing of Scott Wilson this evening. We had just completed the NYCC Walking Dead panel on which the crowd erupted in cheers when Angela Kang announced that he’d be appearing on season 9 at some point. A little less than an hour later I got the terrible news. All of the best parts of Hershel Greene came from Scott—he was so incredibly sweet, warm, and wise. When we lost Hershel on the show it was a week after my own father passed away and when Scott came on Talking Dead he said so many kind and wonderful things to me afterwards that brought me great comfort. I really will miss him and the gentle, compassionate eyes that gave Hershel so much soul. I am so sad to know that the world is without him tonight. It’s important to me to let you know that we pretaped the first episode of Talking Dead last week when the cast members were in LA for the WD premiere screening so please know that is the only reason why we don’t pay our respects to him in our show tomorrow. #RIPScottWilson
