Unfortunately, IMAX is deliberately misleading with their branding. In the mid-2000s, they introduced the IMAX MPX theaters, which could be retrofit into existing multiplex movie theaters instead of requiring a new building to be constructed like with real IMAX. The screens are 1/6 the size of real IMAX, they use 2K digital projectors instead of 70mm film, and the image is cropped to the traditional widescreen film aspect ratio. The worst part is that you typically get charged the same amount of money as if you went to see the film in a real IMAX theater. The vast majority of IMAX theaters you see are the MPX ones, and you have to look up special lists to see which theaters in your area (if any) are genuine 70mm IMAX.

Comment here is about the 70mm film IMAX Screens. There's a variety of different formats for IMAX. But only 30 of the screens in the world are capable of playing the 70mm film format.

It's true. 19 in the United States.

Nolan only distributed 100 reels worldwide for Oppenheimer.
