Tragedy strikes during production of The Dark Knight Rises. Warner Brothers confirmed that an unidentified male extra passed away from natural causes on the set of the new Batman film.

"The studio can confirm that a male extra passed away while on a break during an off-set crowd rehearsal for a sequence with several hundred extras in early November. The production crew fully cooperated with the authorities' investigation, which established that he died of natural causes," a studio representative said.

Sources reveal that the man's unconscious body was found after he had walked away from the other extras; a medical crew was called immediately. "He was taken to the hospital straight away... It was during a period when the film was shooting a huge sequence with several hundred extras in the Wall Street area," a source said.
