Yeah, I remember the one-sheet, and believe they used it for the video cover as well. I vividly recall Praetorius staring at me from the shelves of the horror section, compelling me to rent the movie just to find out what the hell was going on in that picture. That image might have worked better for the DVD release, but I don't know.
As far as this goes, the image is simple and kind of cool, but I agree with Death Surge; it doesn't really have anything to do with the movie.
