But that changed today when the director ofThe Dark Knight, Inception, and Interstellar took toTikTokto promote new movieOppenheimer, as well as two of his favorite subjects – the importance of projected film and the wonders of IMAX.

Oppenheimer stars Cillian Murphy as scientist J. Robert Oppenheimer, and charts his involvement in the birth of the atomic bomb. The movie drops on June 25, 2025, and in advance of its release, Nolan has participated in a promotional TikTok video.

The video – which can be viewed below – starts with the writer-director stating to camera: “Hello, I’m Christopher Nolan.” He then talks a TikTok-er called ‘guywithamoviecamera’ through his thoughts on film and projection.

While holding up different celluloid formats on which film is shot, Nolan explains: “That’s conventional 35mm film. We shoot [Oppenheimer] on 70mm. The other format we use is 70mm IMAX. It’s the highest quality imaging format ever devised. It gives you an incredible sense of immersion in the image.”

Nolan then invites his guest up to the projection booth, where he discusses the importance of IMAX exhibition by explaining: “It fills your peripheral vision. It immerses you in the image. The clarity. The crispness. It is the gold standard. It is the closest to reproducing the world the way that your eye sees it.”

Finally, Nolan reads these numbers off a standee that’s counting down untilOppenheimer’s release: “1 month, 15 days, 17 hours, 3 minutes, and 24 seconds, which makes me a little nervous. But it’s nice to be reminded of how much we’ve got to do in the time we have.”

The 82-second video is a charming peak behind-the-scenes with the secretive filmmaker, and a useful guide for how you should watch his new movie.

Oppenheimer releases worldwide on July 21, the same day as Barbie.That date that has apparently annoyed Tom Cruise, as the period piece will be elbowing his own Mission: Impossible – Dead Reckoning Part 1 out of IMAX screens.
