 The union representing film and TV crew members has reached a tentative agreement with the major Hollywood studios. NPR's Mandalit del Barco reports members still need to ratify the basic agreements of the deal. The International Alliance of Theatrical Stage Employees, or IATSE, represents 50,000 below-the-line workers in Hollywood, including cinematographers, costume designers, makeup artists, hairstylists, set decorators, lighting technicians, and other craftspeople.
