Me-ow! Sarah Silverman and Isla Fisher get their claws out for laughs in MyDamnChannel.com’s upcoming Web series Pilot Season – and PEOPLE has an extended sneak peek at their hilarious verbal attack scene.
The series, which also stars David Cross, Andy Dick and Sam Seder, is a mockumentary that follows the lives of desperate actors, agents and executives during the TV industry’s competitive pilot season.
Silverman, 38, plays an actress while Fisher, 33, is a personal trainer in the webisodes, which were filmed five years ago and originally aired on the now-defunct Trio channel. The 30-episode Web version of the series debuts its first two episodes on Monday.
