Veteran actors Harrison Ford and Anthony Hopkins are all set to star in espionage thriller "Official Secrets."
They will be joined by Paul Bettany, Natalie Dormer and Martin Freeman, reported Variety.
The film centres on a young British intelligence officer who became famous when leaking information to the press, alleging that the NSA was engaging in illegal activities in order to pressure the UN Security Council to approve a resolution of war against Iraq in 2003.
The move is based on the book, "The Spy Who Tried to Stop a War: Katharine Gun and the Secret Plot to Sanction the Iraq Invasion."
Justin Chadwick is attached to direct the project from an adapted script by Sara and Gregory Bernstein.
The principal photography is slated to begin in May in the UK.
