Coming soon says:
As filming continues in Jodhpur, India on Christopher Nolan's third Batman film, The Dark Knight Rises, more photos have been snapped from around the set. Today's images arrive courtesy of Mehul Gohil at the Facebook fan page The Dark Knight Rises Community.
The below photos offer a better look at the alleged chroma-key "Lazarus Pit" revealed last week and also seem to confirm the presence of Josh Pence (who will be playing a young Ra's al Ghul) at the site of the production.
The final image is described as a "training arena" being utilized by the character.
