01 — THE FORMAT

FIVE FEET OF FILM,
EVERY SECOND.

15-perforation 65 mm film — “IMAX 15/70,” the largest format in cinema. It moves more than five feet of film a second. That speed is exactly why it’s so loud.

03 — THE NOISE PROBLEM

STILL TOO LOUD
FOR DIALOGUE.

Even quieter than before, it was still too loud for dialogue, so IMAX built a soundproof housing — the “blimp.” Fully rigged, the system weighs 300–400 lb and needs steel-plated dollies.

04 — THE EYELINE FIX

EYE CONTACT,
BY MIRROR.

The blimp was so wide it blocked the actors’ eyelines. On tight two-shots, Nolan and cinematographer Hoyte van Hoytema mounted a double-mirror periscope so the actors could hold eye contact through reflections — with the huge camera between them.

05 — THE MAKING-OF

Nolan challenged IMAX to build a camera that could shoot an entire feature — dialogue and all. They delivered.

“If ever there were a story where you want to do the whole thing on IMAX, this is it.”— Christopher Nolan
