Easily the best thriller set in Belfast, taken from Gerald Seymour's excellent novel. The film benefits from a degree of accuracy you will never find in 'The Devil's Own,' 'Patriot Games' or any of the other Hollywood nonsense. A good cast with many Belfast actors adds realism and the story is fast-paced and believable. The opening sequence is shocking, but again very detailed and the use of the IRA CO as a voice-over is pretty clever. The tension as the IRA close in on Harry is palpable as is his feeling of isolation and all the characters are three-dimensional. Leeds was used for some filming, but it feels like Belfast and there is good use of Belfast locations as well, especially during the climax. 'It was well done, Billy...'
