Is this the first set shot from Dark Knight Rises?

No matter how much of a tight grip Christopher Nolan attempts to keep on his Dark Knight Rises , massive interest in the director's third Batman film is going to make it difficult for him to keep tabs on everything that goes on.

Which could explain the above photo, apparently leaked from the in-production set of Rises , and shows off the front of famous insane asylum Arkham.

Though the authenticity of the image is still being confirmed, the person who provided the photo apparently has a “good mate” working on the Cardington set.

Could this simply be left over from the Nolan’s other two Batman films? Either way, it’s got us desperate for the film to start rolling in May, when no end of genuine photos are sure to hit the web.

The Dark Knight Rises opens 20 July, 2012.
