Six scenes from The Dark Knight were filmed with IMAX camera. So when you watch the movie on an IMAX screen only those six scenes will fill the entire screen. The other part of the movie is like watching a DVD in the widescreen format but ten times bigger and better. The biggest difference between regular and IMAX besides the giant screen is the experience factor that IMAX brings. Talk about surround sound your seat shakes with every explosion. See how much more you get with IMAX.
