Paget Brewster and Keith David More

Get ready to see a pair of new faces on the Greendale campus next season.

Paget Brewster (Criminal Minds) and Keith David (Enlisted) are joining the cast of Community, which returns for its sixth season next year exclusively on Yahoo. Brewster will play Francesca "Frankie" Dart, a consultant brought in to help whip the school into shape (good luck with that), while David plays retired scientist Elroy Patashnik. (It's not clear if Elroy is a student or a professor at Greendale... but that's a fine line, anyway.)

Both Brewster and David boast serious sitcom cred. Along with her six seasons on Criminal Minds, Brewster played Joey's (and then Chandler's) girlfriend Kathy in a memorable Friends arc, and later guest starred on Two and a Half Men, King of the Hill, and Modern Family. David played tough guys for years in movies like Platoon and Armageddon before cracking us up as Command Sergeant Major Donald Cody on Fox's late, lamented military comedy Enlisted.

(Weirdly, Brewster actually guest starred on Community last season, as IT department head Debra Chambers. Hmmm... will Abed notice that Frankie and Debra look just alike?)

Brewster and David should help fill the void left by a few departing Community cast members: Yvette Nicole Brown (Shirley) announced in September she'd be leaving the show to care for her ailing father, and last season saw the exit of Donald Glover (Troy). Plus, co-stars Jonathan Banks (Buzz) and John Oliver (Professor Duncan) aren't expected back, since they're busy working on Better Call Saul and Last Week Tonight, respectively.

But never fear, fans: Main cast members Joel McHale (Jeff), Gillian Jacobs (Britta), Danny Pudi (Abed), Alison Brie (Annie), Jim Rash (Dean Pelton), and Ken Jeong (Chang) are all back for another semester at Greendale.

We have a little more information on Community Season 6 to share as well: Production gets underway Nov.17 (that's next week!), and the 13 new episodes will air early next year on Yahoo. Are you excited yet, Human Beings?

Community Season 6 premieres in early 2015 on Yahoo Screen.
