I'm just pulling this out of the Sucker Punch thread since it confused people.
The gist of it is, not all IMAX theaters are really IMAX.
A quick google and here is what I found (in about 30 seconds)
how to find a real IMAX theater, and avoid the fake ones
Earlier this year, I wrote about the growing fan outrage over the retrofitted 35mm screens that now bear the label IMAX but arenít anything like what weíve come to expect from the format. I also wrote, earlier today, about how I saw very little difference between Avatar in IMAX 3D and Avatar in non-IMAX 3D.
If you really do want to indulge in the extra cost for IMAX -- for Avatar or for any other film -- then I implore you to be sure that youíre paying for a genuine IMAX experience. The independent trade journal of large-format cinema LF Examiner has put together these Google Maps that give you all the details of every screen labeled IMAX in the United States or Canada... with an explanation of why some screens are better than others.
Even the official IMAX site doesnít give you this info... and with good reason. They donít want you to know that youíre not always getting what you pay for.

Original Article that started people wondering about all this:
Since September 2008, IMAX has been installing "Digital IMAX" in AMC theaters that are on screens only slightly bigger than a regular movie screen and of only slightly higher quality. AMC advertises these screens as IMAX with no distinction between large screens and small screens. This phenomenon has recently been publicized on Aziz Ansari's blog where he has denounced the practice. I'm sure Mr. Ansari isn't the only person who does not want to spend $5 more for a movie that is little different than the one in the theater next door, so here are some tips to avoid these theaters.
Call the theater you plan to visit and ask what size screen your movie will be played on. Real IMAX screens are 76 by 97 feet and the fake screens are 29 by 58 feet. This way you will not be surprised after your ticket has been ripped and you are sitting down to enjoy your movie.
Don't see IMAX movies in AMC theaters, especially those converted after September 2008 since it is highly likely they will be small screens.
Boycott AMC theaters if you feel strongly about this issue. You don't need to give your business to a company you don't agree with.
If you are especially concerned with the dilution of the IMAX brand, boycott IMAX. There is no better way to make your opinion known to a corporation than by not using their services.
