Presentation of the Film US at the Confluence Theater, Federal Pavilion, HemisFair '68
A Confluence Theater was designed in accordance with the theme of the U.S. Pavilion at HemisFair ‘68, “The Confluence of Cultures in the United States.” Theater technology and film projection were combined to enable the audience to participate in this “confluence.” The film required three screen formats: 30 × 15 ft, 30 × 25 ft and finally 140 × 37 ft. “Flying” the smaller screens and theater walls into the ceiling provided the confluence of three 400-seat audiences into one audience of 1200. Three standard 35mm projectors and three 70mm projectors, with films enlarged from 35mm negatives, were employed; 2500-W and 6500-W xenon arc lamps provided illumination and seven channels supplied mono and stereo sound to the specially designed theater. Precise timing of the projected picture, sound, flying screens and flying walls required total automation.
