As reported by the United States Access Board:
As of June 2, movie theaters showing digital movies must provide a means for delivering closed captioning and audio description under rules issued under the ADA by the Department of Justice (DOJ). Issued 18 months ago, the rules supplement provisions in DOJ’s ADA regulations on provision of auxiliary aids and services. Movie theaters that show digital movies equipped with closed captions and audio description must acquire and maintain equipment for displaying captions and transmitting audio description.
