The conversation when George (Jason Alexander) goes up to Larry Hankin (the guy playing Kramer) telling him to say his lines differently actually happened between Larry David and Michael Richards.
Larry Hankin, who auditioned for Kramer on "Jerry," actually had auditioned for Kramer on "Seinfeld."
Tom Cherones played the director of the 'Jerry' pilot while also directing this 'Seinfeld' episode. Tom also directed almost half of all Seinfeld episodes. This was his first of two on-screen performances in the series, the other being in the final episode.
Rosie O'Donnell, Patricia Heaton, Mariska Hargitay, Jessica Lundy, Amy Yasbeck and Megan Mullally auditioned for the role of Elaine in Seinfeld. Mariska Hargitay would return playing an actress auditioning for Elaine in 'The Pilot.'
This two-part episode aired at an earlier time, 8:00 PM, to make room for the two-hour finale of Cheers (1982), whose time slot would be claimed by Seinfeld at the start of the new fall season.
