Jeffrey Dean Morgan says he never gets tired of playing Negan because the "Walking Dead" antagonist is always growing and adapting to new situations.

In 2021 Hilarie also made an appearance on The Walking Dead, playing his character Negan's late wife Lucille in a flashback scene. That same year their son Gus also made his acting debut as a young zombie. "My dude. Me, @hilarieburton and George … THATS MY BOY!! We are super proud of Gusy Dean," Jeffrey wrote on social media.
