Alex Borstein was the original choice for Sookie St. James in Gilmore Girls (2000). She was replaced by Melissa McCarthy.
Alex Borstein couldn't get out of her contract for MAD TV to play Sookie, so she guest starred occasionally as Drella instead.
The role of Dean Forester in this unaired pilot was played by Nathan Wetherington. He was replaced with Jared Padalecki.
