 On this movie set, the cast and crew treat the background players (a.k.a. atmosphere, extras, props that eat) like crap. Jane Walter, played by Alison Tuma and a member of the under-class of extras, won t stand for this treatment. She incites a rebellion. The background performers stand up for their rights, and they voice their demands. They don t get everything they want, but they do get their own canvas chairs.
