It seems the first set photo from Christopher Nolan's The Dark Knight Rises has been released, despite the fact that filming hasn't started yet. Take a look at the photo below, which reveals the Arkham Asylum.
By request, these photos have been removed.
The photo was taken on a set in Cardington, England. It is possible this photo was taken of an older set from Batman Begins or The Dark Knight, both of which shot in Cardington. The Dark Knight Rises will be filming in Los Angeles, Detroit, Bucharest and in the United Kingdom, so it is possible this could be a new set. Production will start on The Dark Knight Rises in April.
