Three top US senators, including former White House hopeful John McCain, slammed the new film detailing the how U.S. intelligence and elite commando units succeeded in locating and taking out Osama bin Laden  for suggesting that torture methods were used to helped find the Al-Qaeda chief.

In a letter to Sony Pictures head Michael Lynton, Democratic senators Diane Feinstein and Carl Levin and Republican McCain expressed their grievances with the film, "Zero Dark Thirty," by Oscar-winning director Kathryn Bigelow.

"The film graphically depicts CIA officers repeatedly torturing detainees and then credits these detainees with providing critical lead information on the courier that led to" Bin Laden, they wrote, according to AFP.

"Regardless of what message the filmmakers intended to convey, the movie clearly implies that the CIA's coercive interrogation techniques were effective in eliciting important information related to a courier for" Bin Laden.

"We have reviewed CIA records and know that this is incorrect. 'Zero Dark Thirty' is factually inaccurate, and we believe that you have an obligation to state that the role of torture in the hunt for (Bin Laden) is not based on the facts, but rather part of the film's fictional narrative."

The movie, which was released in North America on Wednesday, tells the story of the decade-long search for Bin Laden, the CIA's most wanted man in the world, after September 11, 2001, climaxing in last year's dramatic and deadly raid on Bin Laden's hideout in Abbottabad, Pakistan.

A CIA agent played by Jessica Chastain -- tipped for the best actress Oscar for her role -- drives her bosses relentlessly to focus on leads which eventually identify the courier who totes messages to and from the Abbottabad compound.

The film -- named after military-speak for the time of night during which the Abbottabad raid took place -- pulls no punches in showing the use of torture and harsh interrogation techniques like water-boarding to force captives to speak.

In response to an AFP request for comment, a Sony Pictures spokesman pointed to a statement given last week by Bigelow and screenwriter Mark Boal, who worked with her on 2008's Oscar-winning "The Hurt Locker."

That statement read: "This was a 10-year intelligence operation brought to the screen in a two-and-a-half-hour film. We depicted a variety of controversial practices and intelligence methods that were used in the name of finding bin Laden.

"The film shows that no single method was necessarily responsible for solving the manhunt, nor can any single scene taken in isolation fairly capture the totality of efforts the film dramatizes."

Levin is chairman of the Senate Armed Services Committee, on which McCain is ranking member, while Feinstein is chairman of the Senate Select Committee on Intelligence.
