"The sharpness and the clarity and the depth of the image is unparalleled,” Nolan said. “The headline, for me, is by shooting on IMAX 70mm film, you’re really letting the screen disappear. You’re getting a feeling of 3D without the glasses. You’ve got a huge screen and you’re filling the peripheral vision of the audience. You’re immersing them in the world of the film.”
For Nolan, the “best possible experience” to view “Oppenheimer” in theaters is the IMAX 70mm film presentations. These are also among the rarest, currently set for 25 locations in North America including the AMC Universal CityWalk in Los Angeles, the AMC Lincoln Square in New York, the Cinemark Dallas, the Regal King of Prussia near Philadelphia and the AutoNation IMAX in Fort Lauderdale.
