Theater Facts

Projection Screen
Four and a half stories tall and six and a half stories wide, or 44- by 66-feet (13.4- by 20.1-meters).

70mm film with 15 perforations. It is the largest film-frame size in use.

The IMAX film is ten times as large as 35mm film and three times as large as standard 70mm with five perforations.

Film Projector
The projector system weighs 3,900 pounds (1,769 kilograms) — nearly two tons (1.77 metric tons). The system is designed and built by Imax Corporation, Mississauga, Ontario, Canada. The projector handles 330 feet (100 meters) of film per minute. This is roughly similar to an average adult walking pace, or about 2.5 miles (4 kilometers) of film per 40-minute show! The film moves at twenty-four frames per second and moves horizontally rather than vertically. The film is wound on magnesium reels that are four feet in diameter.

Sound System
The IMAX six-channel high-fidelity motion-picture sound system with sub-bass is manufactured by Sonics Associates, Inc. Fifty-eight speakers surround viewers. The sound is produced at a low frequency, which can literally make shirtsleeves vibrate. Soundtracks for IMAX productions are produced separately from the film and are played from a computer hard drive.

Theater Design
The seating platform is angled twenty-five degrees to the floor. Heads of viewers are level with knees of spectators one row back. Everyone has an unobstructed view of the screen. The image fills both horizontal and vertical peripheral vision. The image expands vertically and horizontally. The theater can seat 441 people.
