So “Who’s the Caboose?” is this 90s-era mockumentary about the process of auditioning during pilot season in LA. There are some sharp moments in the script referencing the dearth of feature roles for women. I found the following very short segment pretty incisive. http://www.hulu.com/watch/276281/whos-the-caboose?c=2257:2281
Offscreen: So what is it you’re auditioning for?
Sarah Silverman: Well it’s really exciting, because um, the lead character is funny, and dynamic, and charismatic, and quick-witted, and really suave, and just a dream role. And uh, I’m auditioning to play his wife.
