Tom Hiddleston revealed that whilst living on location for this film, he accidentally exposed himself to all of his colleagues. He had been alone, tidying up after having showered, when the rest of the cast walked in just as his towel fell off.
Not all of the cast are professional actors, the Leightons' painting tutor Christopher is played by Christopher Baker, a real-life artist.
In order to keep production costs down, the costumes for all the characters were bought from London charity shops.
Tom Hiddleston revealed that one of the inspirations for Edward's character is the boy from Der Schneemann (1982) , which inspired him to choose a similar set of pyjamas for Edward.
The film was shot in script order, with the cast living on location for the duration of the shoot.
