Guy Haines, played by Paul Ritter has a small, but important role in the film Quantum of Solace.
Despite his very low profile, Guy Hainesis one of the closest advisors to the British Prime Minister, and possibly the highest-ranking member of Quantum known to MI6. He is identified by Bill Tanner using Bond’s surveillance photos of Quantum’s leadership at the Tosca opera, and is discussed later by Bond and RenĂ© Mathis. Haines’ role in the film was initially scripted to be larger: in a deleted scene from the epilogue, Bond confronts both Haines and Mr White.
However, director Marc Forster cut the scene as he felt the film had a better ending after the meeting with Yusef Kabira and Corrine Veneau, and did not want to wait for EON Productions to commit to a third film if they did not want to. The scene with Bond meeting Haines appears on the DVD release as a special feature. Haines shares his name with the protagonist of Alfred Hitchcock’s Strangers on a Train, though whether he was given this name by the writers as a tribute or as a code-name within Quantum remains to be seen.
