The Fourth Protocol (film) - Differences From The Novel

Differences From The Novel

• The film opens with the killing of Kim Philby, who has already planned the operation, because he knows too much. In the book he remains a key figure.
• The film begins with Preston breaking into Berenson's house to expose him as a traitor. In the novel, the character of Jim Rawlings, a professional thief, robs Berenson's house and unintentionally discovers the stolen documents, sending them anonymously to MI5 so that they might find the traitor.
• The political plot of the book to allow the Labour Party to win the general election and allow for a Communist take over the party is taken out.
• The film removes a large section of the book in regards to John Preston's investigation into Jan Marais in South Africa.
• Some of the locations are changed from the book. The Greek cafe is in Chesterfield, not Colchester, and Petrosfy's house is in Ipswich not directly next to the air base.
• The airbase in the book is the real base of "Bentwaters" which is changed to "Baywaters" in the film.
• The character of the assembler in the book is a man although the surname is the same. He is killed by getting his neck broken rather than being shot.
