Casting Assistants: This is the entry-level position in the field of casting. These people go above and beyond the call of duty of your typical office assistant. They do everything from covering phones, to making copies, setting up audition (aka "session") equipment like lights, the camera, sound equipment, etc. They sometimes can be found in the office relaying audition appointments, checking actors avails, or in the casting room making sure the recording software is running smoothly so the Casting Director can focus on each actor's performance.
