In an earlier post in this thread, IMAX was characterized as being a "narrow" aspect ratio. My take on it is that it's really a "tall" aspect ratio. IMAX films are created to be projected on a very large screen, creating an environment that the audience is immersed in. It's been a while since I've seen an IMAX film, but as I recall the top & bottom of the screen usually has only peripheral information that you don't really need to look at directly. Occasionally there's something that you will look up or down at, and that's one of the things that helps give the format its "wow" factor.
Apparently the "book" on how to film in IMAX recommends putting the actor's foreheads center screen. That leaves an AWFUL lot of headroom on the format. This was not lost on the DP of the Dark Knight who discusses this in American Cinematographer. They choose to ignore that advice and shoot their own tests. To me, the movie "plays bigger" when the advice is not followed.
I am lucky to have two IMAX theaters in my town, one next door to my building. Literally, it's a 2 minute walk. So I get to see the format regularly when funds permit. I find that it is now my preferred format for 'big" film. It is somewhat difficult for me though as a "movie" fan to watch movies that were shot anamorphic, go through the DMR process and get essentially panned and scanned to fit IMAX. If the movie was shot 1:85 it's a bit easier.
