This smartly crafted sitcom stars Emmy-winning series creator Tina Fey as Liz Lemon, an unlucky-in-love New Yorker who heads up a ragtag team of writers on the fictional NBC variety show "TGS with Tracy Jordan." The top-notch ensemble cast also features Alec Baldwin as pompous network executive Jack Donaghy, Tracy Morgan and Jane Krakowski as the pampered stars of "TGS," and Jack McBrayer as a relentlessly upbeat NBC page.
