Community has added two series regulars for its upcoming sixth season on Yahoo! Screen.

TV Guide reports Paget Brewster (Criminal Minds) will play Francesca "Frankie" Dart, a consultant hired by Greendale Community College, while veteran actor Keith David (Enlisted) will portray Elroy Patashnik, a retired scientist who comes to the school to reinvent himself.

Both actors have appeared on the comedy before: Brewster as IT department staff member Debra Chambers in the Season 5 episode "Analysis of Cork-Based Networking," and David as the narrator of the Season 3 episode "Pillows and Blankets."

They fill recent vacancies left by Yvette Nicole Brown, who's joined the cast of CBS's Odd Couple remake, and Jonathan Banks, who's reprising his role as Mike Ehrmantraut on the Breaking Bad spinoff Better Call Caul.

Filming is set to begin on the 13-episode sixth season on Nov. 17.
