While "30 Rock" is known for its amazing stunt casting—Jennifer Aniston, Oprah, Jon Hamm, and Matt Damon, to name a few—the stars of the sitcom were always the cast. And when the show premiered in 2006, the only big name among them was Alec Baldwin. (Well, Tina Fey was there but her fame was nowhere near as widespread as it is today. This was pre-Sarah Palin.) In addition to revitalizing Baldwin's career, this lovable, insider-y show also introduced the public to the incredible talents of a group of fairly unknown actors.
In honor of Thursday's series finale, we look back on the actors we will forever know and love because of "30 Rock."
