By 8 October 2013, principal photography had begun, with the shooting being done at the University of Cambridge, and at other locations in Cambridgeshire and across the United Kingdom. Prior to the start of principal photography, Working Title had begun shooting on the lawn in front of the New Court building from 23 September 2013 to 27 September 2013; they filmed the Cambridge May Ball scene, set in 1963. On 24 September 2013, scenes were filmed at St John's College, The Backs in Queen's Road, and Queen's Green. The New Court lawn and Kitchen Bridge were included features in the filming location of the piece. The May Ball scene was the last of the outside shoots, with filming in a lecture theatre the following day, and the remaining filming completed in the studio over the final five weeks of production.
