My brother does advance screenings for studios, directors, etc., and has already seen The Dark Knight several times. (As you can imagine, he has seen just about every movie out for the past 10 years.) He gives The Dark Knight his highest praise and says that everyone has to see it in IMAX - if you just see it in a regular theater, you'll miss out because some of the best scenes were shot in the IMAX format. He said he would actually pay to see the movie...if my brother says he would pay for something he's forced to watch every day, it must be good!
