The Fourth Protocol (film)
The Fourth Protocol is a 1987 British Cold War spy film starring Michael Caine and Pierce Brosnan. Directed by John Mackenzie, it is based on the 1984 novel "The Fourth Protocol" by Frederick Forsyth. Plot. In 1968, an East-West agreement is established to halt nuclear proliferation. One of its clauses, the Fourth Protocol, forbids the non-conventional delivery of a nuclear weapon to a target. MI5 officer John Preston breaks into the residence of British government official George Berenson on New Year's Eve and finds a number of top secret NATO files that should  not have been there. He reports his findings to high-ranking British Secret Service official Sir Nigel Irvine, who deals with the leak. Preston's unauthorised method of retrieving the documents embarrasses the acting Director of MI5, Brian Harcourt-Smith, and as punishment for his insubordination, Preston is relegated to lowly "Airports and Ports". KGB officer Major Valeri Petrofsky is sent on a mission to the United Kingdom by General Govorshin, the head of the KGB. Govorshin's subordinate, Pavel Borisov, complains to his old friend General Yevgeny Karpov, about his department being stripped of resources and personnel, particularly his  star officer Petrofsky. A surprised Karpov quietly investigates and learns about Petrofsky's unsanctioned mission – to violate the Fourth Protocol by assembling and detonating an atomic device as a false flag, to appear to be an American nuclear accident at a nearby military base, intended to strain British-US relations and strengthen the anti-nuclear movement in advance of an election in favour of the Soviet Union. In Glasgow, a Soviet sailor is struck by a truck while fleeing from a port guard. Among the dead man's possessions, Preston finds a disk of polonium, which could only be useful  as a component of a detonator for a bomb. He informs Harcourt-Smith, but is promptly suspended, as Harcourt-Smith believes that Preston is manufacturing a fake incident to work his way back into MI5. Preston, however has the confidence of Sir Bernard Hemmings, the gravely-ill Director of MI5, as well as Irvine, who is happy to sidestep Harcourt-Smith's directives. Preston sets to work and eventually comes across Winkler, a known Czech KGB agent, and tails him from the airport. Meanwhile, Petrofsky meets KGB agent Irina Vassilievna, a bomb expert who is pretending to be his wife . Under her guidance, they assemble the device from the smuggled items and she sets it on a two-hour delay as they agreed on. Unbeknownst to Petrofsky, Vassilievna follows her own orders, resetting the delay to zero. After sleeping with Petrofsky, she finds his own secret order to eliminate her and tries to warn him about the double-cross, but he kills her before she can. Afterwards, Petrofsky is observed contacting Winkler. Preston tracks him to Ipswich, loses him, then finds him again. Preston eventually realises that Petrofsky's target is RAF Baywaters, and locates Petrofsky's house, which lies  right next to the base. When Petrofsky starts to activate the bomb, on an impulse, he checks the timer first and realises he has been betrayed. At that moment, an SAS team storms the house and during a struggle, Preston subdues and disables Petrofsky. To Preston's outrage, one of the SAS team cold-bloodedly shoots and kills Petrofsky, explaining bluntly afterwards that he had orders to do so. At Hemmings' funeral, Preston is unsurprised to find Irvine secretly meeting with General Karpov. Preston had become suspicious when known KGB agent Winkler was used as a courier, making it easy  to follow him, and also when Petrofsky was killed instead of being captured for questioning. He surmised that discrediting Govorshin would benefit both Irvine and Karpov (sneering to both that keeping hold over their careers is all that matters to them). Preston does not see any point in exposing them and leaves after expressing his contempt for their cynical power play (Irvine secretly assuring Karpov that they have control over Preston, as they covertly observe him reunite with his young son). Production. Michael Caine read the draft manuscript of the novel and suggested to Forsyth that they produce a film  together. They hired George Axelrod to write a script and John Frankenheimer to direct, but were unable to raise finance. Axelrod and Frankenheimer left the project, Forsyth wrote the script himself and they got a new producer and director. Locations. Much of the film was shot in the Heelands district of Milton Keynes, the main house featured is on Tranlands Brigg, Heelands, Milton Keynes. Scenes set on the London Underground were shot at Charing Cross, Green Park, and Aldwych stations. Colchester Station was also used in one scene, with star Michael Caine filmed standing on the tracks. For some of  the interiors, rooms of King's College London on the Strand were used. The "RAF Baywaters" scenes were filmed at the now defunct RAF Upper Heyford as a take on the real life RAF Bentwaters. Filming also took place in Finland. Towards the end of the film, the car chase in Ipswich is actually shot in Chelmsford on the A1016 Chelmer Valley bypass which at the time was newly built. One shot shows helicopters flying under the Orwell Bridge which is often considered a local landmark. Eastbourne Mews, W2, was used as the filming location for John Preston's (Michael  Caine) house. Reception. Box office. The film debuted at no. 4 at the box office with $3.6 million in ticket sales. In the UK it made £766,413. Critical response. Rotten Tomatoes retrospectively gave the film a score of 74% based on reviews from 19 critics. "The Globe and Mail"'s film critic Jay Scott said that "the movie is entertaining on a rudimentary, never-to-be-taken-seriously level. On the rare occasions when it does rise above the material, it's because Pierce Brosnan is chillingly effective as an assassin with the body temperature of a snake . The yarn is otherwise little more than "" tightly re-wound for the age of glasnost." Scott praised Michael Caine's excellent performance, but complained that the "role permits him to display only one of the three dimensions he was able to provide in his portrayal of the father in "The Whistle Blower" (1986)." "Halliwell's Film and Video Guide" described it as a "very competent but somehow old hat espionage thriller", awarding it one star from a possible four. Quoted in Halliwell's guide, "Daily Variety" stated that "there is an uneasy feeling that the whole affair could have been  better made into an excellent miniseries". John Ferguson awarded it two stars out of five for "Radio Times", stating "what once made for diverting summer reading now appears tired and not particularly relevant".
