Hours after Warrior star Joel Edgerton was confirmed as the new film's leading man, America's deputy inspector general for intelligence and special programme assessments, Patricia A. Brannin, revealed an investigation was underway following concerns raised last year (11) by New York politician Pete King.
King raised the issue in August (11) after reading an article about Bigelow and Boal in the New York Times, in which columnist Maureen Dowd suggested the pair was given access to "top-level access to the most classified mission in history".
In a statement obtained by the Los Angeles Times, King writes, "The leaks that followed the successful Bin Laden mission led to the arrests of Pakistanis and put in danger the mission’s heroes and their families.
"Privately, individuals in the intelligence and special operations communities expressed support for my request for a probe. I look forward to an update on the investigation and actions taken thus far."
When King first raised the issue in August, White House spokesman Jay Carney called his claims "ridiculous", stating, "We do not discuss classified information."
Executives at Sony, the film company behind Bigelow's new Bin Laden film, have yet to respond. The movie is scheduled for a December, 2012 release.
