The Hollywood movie about the hunt for 9/11 mastermind terrorist Obama bin Laden relied on information disclosed to its director Katherine Bigelow and the movie's screenwriter Mark Boal by the US Central Intelligence Agency.
The names of key figures involved in the planning of the top secret mission were sought by the non-governmental group Judicial Watch, which had argued in a court filing that since they had been revealed by US intelligence, they no longer could be classified as secret.
US District Court Judge Rudolph Contreras, however, dismissed the petition in an August 28 ruling which found that names of four CIA officials and a member of the Navy Seal team involved in planning the raid were not included in the movie, and therefore could remain secret.
"In short, Judicial Watch does not know -- and outside of this suit, apparently has no way of learning -- the names of these individuals," Contreras said in his ruling.
The US Justice Department had argued that making the names public would create an "unnecessary security and counterintelligence risk."
Contreras issued his decision as defendants accused in the September 11, 2001 attacks await a military ruling in a similar request, expected in a hearing later this month at the Guantanamo Bay military base.
James Connell, an attorney for one of the defendants -- Ali Abd al-Aziz Ali, also known as Ammar al-Baluchi -- is seeking to learn as much as the Hollywood directors got in preparation of the movie.
Al-Baluchi's uncle, alleged 9/11 mastermind Khalid Sheikh Mohammed, also is to be tried at the US naval base in Guantanamo Bay, Cuba.
The other defendants are Mustapha al-Hawsawi of Saudi Arabia and Yemenis Ramzi Binalshibh and Walid bin Attash.
The five face the death penalty if convicted for their roles in the 2001 attacks by Al-Qaeda militants in which hijacked planes were used to strike New York, Washington and Shanksville, Pennsylvania, killing 2,976 people.
