Omnimax and Imax use 70mm film.  And yes the image is allong the sprocket
holes instead of across.  The size for the frame is approximately 70mm
by 50mm.  I have seen a longer format in which a frame was about 2.5
times longer than the standard Omnimax frame.  I believe that this was used
in the GE pavilion at Epcot Center.
