Step 1 : Introduction to the question "Which actor did NOT appear in the “Seinfeld” pilot?"
"The Seinfeld Chronicles" is the pilot episode of the sitcom Seinfeld, which first aired on NBC on July 5, 1989. Unlike her three close friends, Elaine is absent from the pilot episode. The female role was supposed to be Claire, the waitress at Pete's Luncheonette, but Monk's Cafe replaced the luncheonette and Claire was dropped from the role. Elaine would make her first appearance in the second episode, "The Stake Out". Her character was added because NBC executives felt the show was too male-centric, and demanded that creators Jerry Seinfeld and Larry David add a woman to the cast, or the show would not be renewed.
