‘The Dark Knight Rises’ set photo reveals a pit?

A Batman-News.com reader (who wishes to remain anonymous) sent in the first set photo from The Dark Knight Rises’ set in India. The photo appears to be of a giant well covered with a green screen in the middle of the desert just outside the Mehrangarh Fort. Speculation is already soaring around the internet about what this may be used for… I’ll let you guys talk about what you think it could be in the comments. The two day shoot in India is scheduled to wrap up tomorrow.
