Most people, when asked to think about spy movies, will think of James Bond, of Sean Connery or Roger Moore or Daniel Craig. They’ll think of shootouts and stealth and suave secret agents bedding exotic beauties.

The novels of John Le Carré, inspired and informed by Le Carré’s own work for both MI5 and MI6 in the mid-20^th century, are as far from James Bond as one could imagine – though it is just about possible to bend them into something more Bond-like in the name of entertainment, as happened for instance with the TV adaptation of The Night Manager that was released in 2015. As written, Le Carré’s stories are often less thrillers, though they can be thrilling, than tragedies, infused with existentialism, paranoia and a Kafkaesque sense of inevitability. And these are rarely as much in evidence as they are in Martin Ritt’s 1965 adaptation of The Spy Who Came In from the Cold.
