David Morrissey, who played the Governor for two seasons on The Walking Dead, laments his character killing Hershel Greene in season 4. Phillip Blake was first introduced as “the Governor” of the seemingly idealistic Woodbury in season 3 of AMC’s post-apocalyptic series. While at first, the Governor appears to be a good leader, his true nature as a brutal psychopath is revealed as he comes into conflict with Michonne and Rick Grimes’ group at the prison.
"We're all upset [when we're killed off]. The thing I was really upset about was killing Hershel. [Scott Wilson was] one of the greatest men I've ever worked with or known. He loved being on the show, and so did I. You'd read [the script], you'd turn it backwards to make sure you were still alive [laughs]. As the season is going on you think, 'Someone is going to go.' I got to the trailer, looked at [the script], and then I saw I killed Scott.
