If “Tinker Tailor Soldier Spy” leaves you feeling perplexed, you won’t be alone — and the filmmakers won’t be surprised.The Cold War spy pic — adapted from John Le Carre’s 1974 best-seller and set for release by Focus Features on Friday — delves into the layered and paranoid world of Britain’s intelligence service, where intrigue, suspicion and betrayal are the stuff of everyday life. Transparency is the least of its concerns. Instead, the convoluted story offers up endless subplots and red herrings, daring viewers them to sort it all out — which is exactly what director Thomas Alfredson wants them to do. “Too many films today make you passive,” Alfredson said. “They decide everything for you. I try to invite the audience to participate as much as possible.” “Complexity is the foundation of the film,” said editor Dino Jonsater, who had the task of cutting the Byzantine story. “If you clarify things too much you’ll lose the magic.” Following completion of principal photography on 35mm film in London, he and Alfredson — both Swedes — spent the first half of this year in an Avid suite in Stockholm, where they gave the 128-minute, headscratcher its final shape. It was an arduous process. “We moved things around so many times during that period,” said Jonsater. “The more complex a story, the more things you have to try. It’s like taming a beast.” He also had to fight editor’s block just about every day, said Jonsater. “But that is how the work gets done. You get into a hole, pull back, and then find a new way. You can’t let yourself get tired out by that, and you can’t be afraid of dead ends because you learn so much from them.” In Jonsater’s view, every film has an underlying structure that determines how it’s edited, and the editor’s task is to unlock it. “You close yourself in a room with the story and its emotions and discover what it needs,” he said. “The director has a vision, the producer has ideas, I might have an idea. But the bottom line is that you have to find out how the film wants to be edited.” All this can take a lot of time. “You can’t rush editing,” said Alfredson. “You’ve got to get the narration right. Sometimes you need to take a break to get a new perspective on the material. Of course, eventually you have to give it up.” Jonsater said he never reaches a stage when he’s entirely happy with a cut, but he does find the one where he says to himself, “OK, this is good enough, it’s going to work — and that’s probably at the point where the producer is screaming at you. As soon as it’s locked, I’m shit-scared because all the possibilities of what we could have done differently come to mind.” But when he screened the final cut of ‘Tinker’ he was relieved. “I saw that we had made the right decisions.” Bookings & Signings WME signed d.p.
