The film, directed by Kathryn Bigelow, chronicles the decade-long U.S. manhunt for terrorist leader Osama bin Laden.
The Oscar winner and her partner, writer Mark Boal, have been fighting claims they used top secret material to inform the film for the past year and now the Senate Intelligence Committee's chairwoman Dianne Feinstein has created a panel to review all conversations between the Bigelow and Boal and the CIA to determine if spy agency chiefs inappropriately shared classified material with the pair or are responsible for implying torture techniques helped lead to the death of bin Laden, according to Reuters.
Bigelow and Boal, who are not expected to be questioned by the panel members, have denied they had access to material they shouldn't have and recently defended the torture scenes that feature in the film.
The director said, ""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 dramatises.""
