The bottleneck sits in the projection booth

Only 41 IMAX auditoriums worldwide were presenting The Odyssey in 70mm film when IMAX published its August figures. That scarcity is not simply a matter of theaters choosing a premium package. The required projection hardware is old, specialized and difficult to replace.

IMAX chief Richard Gelfond has explained that film projectors are not rolling off a modern production line. Existing machines have to be located, rebuilt and retrofitted. That makes every additional compatible auditorium a small engineering project rather than a software upgrade.

Then there is the print

The physical copy used for an IMAX 70mm presentation of The Odyssey runs roughly 11 miles and weighs about 600 pounds. Handling it requires technicians who can thread, splice and monitor a mechanical film system throughout the screening.

Ahead of release, IMAX contracted around 130 experienced projectionists and put them through an intensive week of training. In some markets, specialists have had to travel because the local workforce that once operated large-format film equipment no longer exists at scale.

The capture side is considerably newer

That aging exhibition chain sits behind a movie made with newly developed production hardware. Nolan and cinematographer Hoyte van Hoytema worked with IMAX on the next-generation Keighley camera and a sound blimp intended to make synchronous recording more practical with IMAX film cameras.

IMAX says the production exposed 2.1 million feet of film. The Odyssey became the first theatrical feature shot entirely with IMAX film cameras, turning the capture format itself into one of the project's defining technical specifications.

Demand is keeping the machinery occupied

The September 3 update extends selected IMAX 70mm engagements through September 30. By August 10, the 41 film locations had already generated $37.5 million. Across digital and film IMAX screens, The Odyssey had reached $289 million and become the company's highest-grossing release.

That revenue explains why scarce equipment, prints and trained operators are still being committed more than two months after opening day.

A successful format that cannot simply scale

The interesting technical lesson is the mismatch between demand and replication. IMAX operates close to 1,900 systems worldwide, yet only a very small subset can reproduce this particular analog presentation. Adding more digital IMAX screens does not increase the inventory of 70mm film projectors.

The Odyssey can therefore extend its run, but its success does not make IMAX 70mm suddenly abundant. Through September 30, the same constraint that made tickets difficult to obtain remains built into the hardware.
