Multiple award-winning comedy series "30 Rock" is told through the comedic voice of Emmy and two-time Golden Globe winner Tina Fey ("SNL") as variety show producer Liz Lemon and features Emmy and two-time Golden Globe winner Alec Baldwin ("The Departed") as top network executive Jack Donaghy and Tracy Morgan ("The Tracy Morgan Show") as Tracy Jordan, the unpredictable star of Lemon's hit variety show, "TGS with Tracy Jordan." Lemon constantly has her hands full, juggling corporate interference from Donaghy and off-the-handle star antics from Jordan, all while attempting to salvage her own personal life.

Also rounding out the cast are Jane Krakowski as Jenna Maroney, the co-star of "TGS"; Scott Adsit as the variety show's producer Pete Hornberger; Jack McBrayer as Kenneth, the over-eager and effortlessly endearing NBC page; Judah Friedlander as Frank, the sardonic slacker on the writing staff; Katrina Bowden as Lemon's young, flighty assistant, Cerie; and Keith Powell as Toofer, the sophisticated yet sarcastic, Harvard-alum writer.
