Talking Dead Guests Are Greg Nicotero, Ron Perlman, & Surprise Walking Dead Cast Member

This week’s celebrity guest is Sons of Anarchy and Hellboy star Ron Perlman, who also appeared on last week’s episode of The Blacklist following Super Bowl XLIX.

Appearing with Perlman are special effects guru Greg Nicotero, who directed the episode, as well as an as-yet-unnamed member of the cast.

While “Surprise The Walking Dead cast member” usually means somebody dies in the episode and is on Talking Dead to say good-bye, that isn’t necessarily true. It wouldn’t be surprising for such a big episode, for the Talking Dead crew to withhold plot-sensitive details such as the introduction of a new character. Aaron, after all, expected to join the cast soon.

The Talking Dead airs on Sunday, February 8, 2015 at 11 PM ET on AMC.

Update: Ron Perlman was originally announced as a guest, but he did not appear on the episode.
