fyi...even though the screen jumps to full 1.78:1 for the IMAX scenes, you're still not getting the full original IMAX picture as it was shot. (IMAX is 1.43:1)

So for the full effect, be sure to visit your local IMAX theatre next month and see it as it was really meant to bee seen. \:\) Yes, that was a completely shameless plug.

note: try to visit the largest IMAX theatre in your area. Not all IMAX theatres are alike. If it's possible avoid the newer "MPX" or Digital screens. While they're better than a 35mm theatre, they're not a full 1.43:1 screen size, which is what you'll want for The Dark Knight.
