Breach is based on the true story of the capture of Robert Hanssen, an FBI agent responsible for many treasonous acts against the United States. Chris Cooper is excellent throughout in portraying a Catholic family man who goes to church constantly with his wife and kids while hiding his sexual perversions. Ryan Phillippe is Eric O'Neill, Hanssen's new assistant who is assigned by boss Laura Linney to keep tabs on Hanssen to use as evidence against him. Caroline Dhavernas as Eric's European wife who wants Eric to come clean about his job, Gary Cole as another agent, and Dennis Haysbert as Linney's superior round out the fine cast in a film that slowly but surely builds up suspense in the various ways of snooping that brings the bureau closer to catching Hanssen in the act of treason. Don't expect James Bond or Alias action here. Do expect an excellent drama about an agent who almost slipped from the FBI's hands.
