'BIG' FILM
The iWERKS system uses 8/70 film, or 70mm film with 8 perforations per film frame. The film is twice as wide as the 35mm film used in many cameras, but the frame area is nearly five times larger, which allows for an image that is crisp and richly detailed.

'BIG' PROJECTORS
To project such giant films, iWERKS has built the most advanced, high precision and powerful projectors system. Designed and built by iWERKS Entertainment of Burbank, California, iWERKS has received an Academy Award for Technological Breakthrough for its innovative projector head design. A 7,000-watt Xenon short-arc lamp is used to project a bright and detailed image. The projector moves 180 feet of film per minute, or about 1.36 miles of film per 40-minute show. The film passes through the projection system at 24 frames per second and is wound up on 4 1/2-foot diameter platters.

'BIG' SCREEN
The large format screen, designed by iWERKS, is composed of a proprietary reflective material and measures 43-by-56 feet, covering a 2,400 square-foot area. Up to five storeys high, they are at least five times larger than a traditional cinema screen and fills the whole field of human vision.

Made of stretched vinyl, coated with a reflective silver paint they are stretched taut over a scaffold frame. With thousands of small perforations they allow sound from speakers positioned behind the screen to play their key role in the total surround sound system.

'BIG' SOUND
Sound is critical to the iWERKS experience. The iWERKS sound system uses a 6-channel Digital DTS cinema processor. Twelve cinema amplifiers, with a combined power of more than 10,000 watts, create an intense motion picture experience. Soundtracks for the films are produced separately from the film and are played from a disc drive within the DTS cinema processor.

'BIG' COMFORT
Our 344 roomy seats are carefully arranged to ensure an unobstructed view as you look up, down, left, and right to take in all the action on the BIG screen.

HOW 3D WORKS?
3D technology is based on human vision. It mimics the way we see the real world. When you look at an object each eye sees a slightly different view and our brain fuses these together into a single 3D image. The two lenses on the iWERKS 3D camera roughly match the distance between our eyes and so each lens ''sees'' a slightly different view. The images are photographed onto two separate rolls of film - corresponding to a right eye and left eye image - which run simultaneously through the camera. These two films are then alternately projected in the theatre.
