Among the other guest stars on tap for the milestone episode, set to air Dec. 5 (during the show’s winter run): TVLine has learned exclusively that True Blood spellcaster Lauren Bowles will play the niece and business partner of Willard’s Santa, who is involved in an unfortunate ziplining (!) accident at their successful Christmas Village attraction.
Also, Christine Woods (Perfect Couples, FlashForward) has been cast as Casey Watson, Buzz’s sister visiting from Seattle. She will — as Closer relatives often do — manage to help the Major Crimes Division solve their latest case.
In addition to her ongoing True Blood run, Bowles has guested on shows such as Curb Your Enthusiasm and Private Practice. Willard’s recent TV credits include Modern Family and TBS’ short-lived Glory Daze; his Closer gig was first reported by EW.com.
The Closer will present its summer finale on Sept. 12, then commence its winter run on Nov. 28.
