70 mm movies were often projected at 30 fps.
Most 35mm movies get projected at 24 fps in the US and some are projected in Europe at 25 fps.

Some IMAX movies are projected at 48 fps. In this case, we're talking about 70 mm film.
The frames are 69mm wide and 48mm tall.

To put this in perspective, the projector moves a strip of film as wide as your hand at a speed of over 3 meters per second!


Those projectors sound like freight trains! The booth has to be sound proofed and the projectionist has to wear hearing projection!
