10. Room Without A View - The Dark Knight
I'm not sure whether or not this is a fully-fledged mistake or not, or the result of somebody wanting to make things symmetrical but overlooking the inherent problems in doing so. Whatever the reason, this
Dark Knight poster doesn't make much sense at all, and the more you think about it, the funnier it gets. So take a look at Batman there, looking all cool and broody... until you realise that he's staring right into a bit of metal. He's just pressed up right against a bit of window, gazing into it. There's no way that anybody would be standing that close and in that position if they wanted to look out at the city. At first you don't notice at all, and then it's ridiculous.
