Critically acclaimed "Community" is a smart, exuberant half-hour comedy series about a tight-knit study group at Greendale Community College. At the center of the group is Jeff Winger (Joel McHale, "The Soup"), a fast-talking lawyer whose degree has been revoked. With some help from his fellow classmates, Winger forms a study group who eventually learn more about themselves than their course work.

Among the series stars who comprise the group are comedy legend Chevy Chase ("Fletch") as Pierce, a successful businessman whose life experience has brought him infinite wisdom; Gillian Jacobs ("Seeking a Friend for the End of the World") as Britta, the 20-something dropout with something to prove; Yvette Nicole Brown ("Rules of Engagement") as Shirley, a sassy middle-aged divorcee; Danny Pudi ("Greek") as Abed, a pop culture junkie; Alison Brie ("Mad Men") as Annie, a high-strung perfectionist; Donald Glover ("30 Rock") as Troy, a former high school football star trying to find his way; and Ken Jeong ("The Hangover Part II") as Chang, the group’s former Spanish professor, turned student. Greendale's fearless leader is Dean Pelton (Jim Rash, "That '70s Show"), an ultra-efficient yet slightly neurotic administrator whose penchant for dressing in costume is well-documented.

After an explosive third year at Greendale, which included Dean Pelton's struggles against Dean Laybourne (guest star John Goodman) and his elite Air-Conditioning Repair Annex, a wedding, a tough biology class and the rise of Chang from campus security officer to megalomaniac dictator, the study group reunites to tackle their fourth year. This season, the group will study history with Professor Noel Cornwallis, played by guest star Malcolm McDowell, ("Entourage," "Franklin & Bash"); they will make an unexpected trip to Pierce’s mansion on Halloween; Jeff will finally meet his long-lost dad; and Shirley will experience the joys of entrepreneurship with her sandwich shop at Greendale.

Tristram Shapeero ("Nurse Jackie") is executive producer/director. The series is a Krasnoff Foster Entertainment production, in association with Universal Media Studios and Sony Pictures Television.
