Its only a couple of stills. It could be worse. You might as well not watch the trailer if you want to completely go in cold. But I know this movie will be hyped as much as the final Potter film, so stuff like this will be impossible to avoid nearer and nearer to the films release. I just stay away from anything that could ruin the plot. Like, we all knew Batman would get the 'bat-pod' in TDK and what the bike looked like etc But we didn't know it was a part of the Batmobile/tumbler until we saw the film. When it transformed and ejected from the Tumbler was one epic moment. I hear yeah. Adapting the Knightfall storyline wouldn't work very well in Nolan's trilogy as there's too many variables to do it justice. But this his Chris Nolan we're talking about. I'm sure hes thought of something different but just as good to work on screen.
