Christopher Nolan's The Dark Knight Rises is easily the most anticipated movie currently in production. As a result, we have to publish all kinds of stories about it, from casting rumors to set photos. Here are the first of the latter group, which appear to show a mysterious puddle of green slime.

Unless you remember your making-of featurettes, in which case you'd know that the color green is often used to remove part of an image and replace it with CGI. So in all likelihood, this puddle won't be bright green when we see it in the movie. Now as to what it could actually be, that's just speculation at this point. I'm going to be bold, and say that it's water. Water puddles are pretty common, so I think that makes the most sense. You read it here first. (Batman On Cinema)
