Pat Caldwell Keeps Odyssey’s 70mm Imax Alive

Retired Imax projectionist Pat Caldwell is the backbone of The Odyssey’s record 70‑mm rollout, training new operators and running 12‑hour night shifts for 3 a.m. screenings across 41 theaters. The project required reviving aging Imax 70‑mm gear, installing a new sound-synchronization system, and solving technical quirks like horizontal film threading and masking. Caldwell’s decades-long journey—from Tennessee’s porn theaters to Imax legend—highlights the craft’s fragility and the fan-driven revival of Nolan’s preferred format.
