 The first such theater, the Cooper Theater, in Denver, featured a 146-degree louvered screen (measuring a massive 105 feet by 35 feet), 814 seats, courtesy lounges on the sides of the theatre for relaxation during intermission (including smoking facilities), and a ceiling which routed air and heating through small vent slots in order to inhibit noise from the building's ventilation equipment..The other two theatres were built in a similar format, however, the last theatre, the Indian Hills Theater had a slightly larger screen and other improvements.
