Nathan Fillion is ducking out of his Castle to shoot a guest spot on Community.
Fillion will appear on the NBC cult comedy as Bob Waite, the head custodian of Greendale Community College, EW has confirmed. (Deadline first reported the news.) In the episode, Annie (Alison Brie) and her criminology professor Buzz Hickey (guest star Jonathan Banks) have to contend with the shrewd Bob.
Walton Goggins will also pop up on Community‘s fifth season, and Rob Corddry, LeVar Burton, and Jon Oliver are slated to make return appearances as well.
