What we have for you that is new today is a list of the guest stars who will be joining Nathan Fillion, Stana Katic, Jon Huertas, and the rest of the cast on Castle’s new journey.

Arye Gross – This is the first credited appearance for M.E. Sidney Perlmutter since “The Way of the Ninja” back during the second half of season 6.

Tim Griffin – The actor was a part of NBC’s “Prime Suspect” remake, and has a big role ahead on Fox’s “Wayward Pines.”

Gia Mora – A lesser-known actress, who has many smaller credits along with an episode of “True Detective.”

Heather McComb – McComb has appeared or recurred on a variety of well-known shows over the past decade and a half, whether it be “Party of Five,” “Prison Break,” or “Ray Donovan” on Showtime.

The most high-profile guest star confirmed to be coming is Annie Wesching, who will appear in the February two-parter as Dr. Kelly Nieman, the mysterious plastic surgeon with possible ties to Jerry Tyson. This episode is most likely going to be standalone, and it will be a surprise if there are any long-term storylines addressed.
