Don’t understand the 70mm IMAX craze for Christopher Nolan’s The Odyssey?

LAist host Julia Paskin talked to Taylor Umphenour, one of L.A.’s top IMAX projectionists, on FilmWeek to understand why the format is becoming a filmmaker favorite and why audiences are clamoring to theaters to see The Odyssey in the largest format possible.

What is IMAX 70mm?

It might be easier to explain in comparison to other formats.

35mm film is 35 millimeters wide, hence its name. 70mm is two times that width.

“ What IMAX did, was they took 70mm film, which runs vertically through the projector, and they turned it on its side, and then they repeated it over three times,” said Umphenour.

Thus, IMAX 70mm is three-times the size of a conventional 70mm film stock and runs through the projector horizontally.

Take a film like Lawrence of Arabia, which was released in 1962 and shot on 70mm film.

“ When you get to IMAX — three times the size of 70 millimeter film, the height of an IMAX film frame is the width of Lawrence of Arabia,” Umphenour said.

In other words, it’s massive — top to bottom.

What does this mean for image clarity?

Again, it may be easier to explain by comparing to other formats — specifically digital.

Most of us know that digital images are made up of tiny, square pixels. The bigger the image, the more pixels it contains, so the better the resolution.

The same is essentially true for film, but film is crystallized through an emulsion process. Chemicals are blended and washed over the film, which develops the image.

Umphenour said this means the image is deeply embedded in the film itself.

“When you increase the size of the film, you increase that clarity and that sharpness because you're allowing the emulsion to contain all that information, but you're giving it a wider image area to hold it,” he said.

In other words, film formats lead to a more organic image. And the bigger the film, the more clarity.

So why aren’t all theaters showing IMAX 70mm?

Currently, there are only 25 theaters in the U.S. capable of showing The Odyssey in IMAX 70mm — theaters with screens large enough to project it.

“ Widescreen fills your field of vision left to right,” Umphenour said. “But what IMAX does, it takes that even further and it fills your field of vision all the way to the top and all the way to the bottom, in that fully expanded aspect ratio.”

So, while not all theaters house screens large enough to project the IMAX 70mm version of The Odyssey, many theaters across the country and in L.A. are able to show The Odyssey in the next best thing… 70mm.

Umphenour helped the Alex Theater in Glendale retrofit its projector and renovate the technical booth so that it could do just that, opting to keep the historical integrity of the theater.

“ We want to maximize the resolution of the film formats that we're using to project there so that people can have the best experience,” he said. “But it's ultimately a more classical, cinematic, theatrical environment.”
