community castle nathan fillion season 5 abc 'Community': 'Castle's Nathan Fillion to guest star on Season 5

“Community” is about to get the king of “Castle” as a guest star. Nathan Fillion is set to appear in an episode of Season 5. Find out who he will be playing here.

We’re not talking about a mystery writer or a futuristic space captain here either. Fillion will instead be playing a lowly custodian (as reported by Deadline). Annie (Alison Brie) and Professor Hickey (guest star Jonathan Banks) meet Fillion’s character, Bob Waite, when the student and teacher team up to navigate Greendale Community College’s network of power.

You see, Bob isn’t just any lowly collector of trash cans — he is the politically savvy head custodian at the school. Considering how powerful the air conditioning repair annex is at Greendale, you can imagine what power the custodial staff yields.

Fillion — who is also known for playing the lead role of Malcolm Reynolds on “Firefly” — is just one of many big-name guest stars coming to “Community” in Season 5. Others confirmed include LeVar Burton, John Oliver, Walton Goggins and Rob Corddry.

“Community” does not yet have an airdate on NBC.
