Well, this sure takes double dipping to a new extreme... On an impulse buy I bought the 2 Disc Unrated Extended cut of Underworld. It was recently on sale at Best Buy with a bonus disc (previewing Underworld 2) for about 15 bucks. I was sure I had previously bought the regular one disc theatrical release a year or so back. Well, much to my dismay, it's the exact same release (minus the U-2 Bonus disc). I cannot take it back because I have already opened it up. As Homer Simpson would say... D'oh!
