Sweatbox - At the old Disney Hyperion Studio, pencil tests of animated scenes were shown to Walt Disney for his approval originally on a Moviola in a small closet with no ventilation. Not only was it hot in the closet, but the animators were nervously awaiting Walt's reaction to their work. Thus, the room became known as a sweatbox. Even after the Studio moved to Burbank and elegant screening rooms were offered to the staff, they were still called by that name.
