Projector, lamphouse and platters. The lamphouse holds a 1000W Xenon bulb, providing the light for the picture. These bulbs are extremely expensive, and can be hard to handle, as full safety gear (helmet with visor Buzz Lightyear style, hard jacket and gauntlets) are required in case the bulb shatters! The blue and red cases you can see are the film transport cases, the film being broken down into about 6-8 individual reels.
