Query: A Great Resource for Aspiring Movie Extras

Author and veteran movie extra Jo Kelly candidly shares her experience in the field of background acting for films in Los Angeles, CA. Included in this handy guide is contact information for casting agencies and casting agenies, calling services, production studios, and tips for how to join the Screen Actors Guild. The business of background acting (from tracking expenses, finding the location of the shoot, and where to turn for tax preparation help) are also covered. This is an excellent gift book for any aspiring actor interested in learning the ropes of show business and finding his-or-her way around LA. Give one to your community theatre director and pass the information on to others who'd like to work as a movie extra.
