Scott Wilson as Hershel Greene

Starring in the series from 2011 to 2014, Wilson’s return to the show for season 9 was announced just hours before his passing. With his scenes for the current season already filmed, it will be the actor’s final performance.

AMC, The Walking Dead’s network, paid tribute to Wilson calling his character ‘the emotional core of the show’.

“Like Scott in our lives, Hershel was a character whose actions continue to inform our characters’ choices to this day. Our hearts go out to his wife, family, friends and to the millions of fans who loved him. Scott will be missed.”

Wilson, whose career spanned more than 50 years, drew critical acclaim for his performances in films such as In the Heat of the Night and In Cold Blood.

He was remembered on social media by the cast and crew of The Walking Dead, including his onscreen daughter, actor Emily Kinney, who described him as “the best TV dad a girl could ask for”.
