Summary
Liza Weil originally auditioned for the role of Rory but was ultimately cast as Paris, a role created for her that showcased her talent and contributed to the success of Gilmore Girls. In fact, at the time of the audition, the character of Paris wasn't planned.
The original plan would have only two girls opposite Rory at the school. Madeline (Shelly Cole) and Louise (Teal Redmann) would have been Rory's enemies rather than Paris. Paris' tenacity, intelligence, and confidence make her a considerable foe.
Gilmore Girls wouldn't have been the same without Paris or Weil. Though she can be a challenge at times, Paris adds a lot to the series. Weil may have lost the role of Rory, but Paris suited her talents better. Weil grew to love Paris despite her rocky start.
