Political satire is so rare that it’s a shame to watch the reliable Ralph Fiennes and Donald Sutherland lend their talents to one that is blind to its own incompetence. In an unnamed place at an unspecified time — can’t you feel pretentiousness creeping in? — a soldier (Fiennes) helps an imprisoned playwright (Sutherland) escape and overthrow a dictator, only to become a dictator himself. In his debut project, writer-director Robert Edwards — a former U.S. Army intelligence officer in Iraq — acts as if he’s saying something profound. He isn’t.
