I saw the very first midnight showing on the Imax screen in Denver. I had anticipated it all week. When the previews started, the front speakers started to rattle, especially during Spiderman 2. I thought maybe it was preview reel, but it did it ALL THROUGHOUT THE MOVIE! Also, the high-end of the audio spectrum kept cutting in and out, and it sounded like the digital signal kept switching to analog. I wasn't the only one who caught this, because I heard someone else commenting on it on the way out of the theater. My friend was mad too. The rattle was OBNOXIOUS! and distorted. Man, last time I saw a movie on the Imax (Lion King) it sounded amazing. I thought they'd check their equipment, I mean, this was Lord of the Rings, for crying out loud. Anyone else have this happen at an Imax showing?
