LONDON (January 10, 2013)--Two former Guantanamo detainees are criticizing "Zero Dark Thirty," a film purportedly based on the real-life hunt for terrorist leader Osama bin Laden that suggests that brutal interrogations provided key intelligence.

Iraqi-born Bisher al-Rawi and Libyan-born Omar Deghayes, who was partially blinded after what he said was an American guard's attempt to gouge out his eyes, said the movie legitimizes abuse.

Speaking on the eve of the 11th anniversary of the opening of the U.S. prison at Guantanamo Bay, the former detainees described the film as an attempt to rehabilitate those guilty of torture.

The film received an Oscar nomination Thursday, but has not yet opened in the U.K.

Neither former detainee has seen the movie but the torture scenes have been widely discussed on both sides of the Atlantic.
