Why King of Prussia's Imax 70Mm Print of 'The Odyssey' Is Such an Elusive Visual Feat

An insightful review of Why King of Prussia's Imax 70Mm Print of 'The Odyssey' Is Such an Elusive Visual Feat—uncover the main takeaways.

Projecting an analog print this large is an unforgiving industrial process. Because 'The Odyssey' features an expansive cinematic runtime passing the three-hour mark, the physical footprint of the print is staggering. It spans roughly eleven miles of acetate and weighs north of 600 pounds.

A standard vertical reel cannot hold this mass without tearing the film under its own weight. The booth at King of Prussia relies on a massive horizontal platter system. The film rests flat on wide steel discs, spooling outward from the center, feeding through a series of rollers into the projector head, and rewinding onto a companion platter in real time.

This operational hurdle requires an expert film projectionist. The technician must manually thread the print through the vacuum-assisted rolling loop mechanism, monitor tension arms, and keep the glass gate clean of microscopic debris. A single friction snag can heat the stock, melt frames, or shut down a screening instantly. Modern cinema projection has become a push-button affair; King of Prussia's booth operates like a mid-century locomotive engine room.
