Why IMAX 70mm
The largest picture film has ever carried, on the largest screens there are. Only 34 rooms in the US and Canada can run it.
The screen
Drag from a person, past a digital IMAX screen, to the largest of the 34.
Not just 70mm
An ordinary 70mm print runs down through the projector, five perforations a frame. IMAX runs the same width of film sideways, fifteen perforations a frame, so every picture is 3.1 times the size.
