Christopher Nolan Says New IMAX Cameras on ‘The Odyssey’ Have Solved the Sound Problems of His Past Films

Much like most of Christopher Nolan’s movies, the dialogue in “Oppenheimer” was criticized by the usual suspects for being inaudible. The complaints centered on the fact that in the three-hour, dialogue-driven film, the sound mixing would at times muffle what the characters were saying.

Nolan’s sound editing and mixing has always been a polarizing topic. Many have wondered why he never addresses the issue, given how frequently detractors bring it up. That criticism might finally subside with “The Odyssey.”

Nolan is making film history with “The Odyssey,” the first narrative feature shot entirely with IMAX cameras. In an interview with Empire Magazine, he called the results “electrifying,” adding: “We never would have been able to get those shots before.”

The footage demonstrated that Nolan can now shoot an entire film using IMAX cameras. In the past, he was limited to using them primarily for action scenes because the cameras were too noisy to capture dialogue at close range. To resolve this, a new IMAX camera housing—known as a “blimp”—was developed, dramatically reducing the noise the cameras produce.

“The blimp system is a game-changer,” Nolan said. “You can be shooting a foot from [an actor’s] face while they’re whispering and get usable sound. What that opens up are intimate moments of performance on the world’s most beautiful format.”

Whether these new cameras will actually change people’s opinions about the sound issues that have plagued some of his films remains to be seen. In a past interview, Nolan blamed the problem on actors not doing ADR, the process of rerecording dialogue in post-production to improve clarity. He also cited the noise of IMAX cameras interfering with quieter scenes. The latter explanation will no longer apply.

The new IMAX technology used on “The Odyssey” includes a “30% quieter camera,” which enhances the clarity of recorded dialogue and the overall sound mix. Other improvements include a carbon-fiber body for lighter operation and an LCD viewfinder.

Nolan has defended the sound in his films before, especially in Tom Shone’s definitive book, “The Nolan Variations,” where he expressed surprise at how “conservative” moviegoers can be about cinematic sound. In the interview, he even described his sound-mixing choices as intentional and “radical.”

But his viewpoint comes from a biased place: he already knows the dialogue in his films inside and out, while audiences are hearing it for the first time and may not grasp everything immediately.

In Shone’s book, Nolan recalls receiving calls from fellow filmmakers who told him they had just watched one of his films and found the dialogue “inaudible.” “Some people thought maybe the music’s too loud, but the truth was it was kind of the whole enchilada of how we had chosen to mix it,” he said at the time.

“The Odyssey” opens in theaters July 17, 2026, from Universal.
