The movie was shot in chronological order.
In the café scene, George (David Sibley) tries to convince Geoff (Sir Tom Courtenay) that playing the ukulele would be a good hobby. In real life, Courtenay is an avid ukulele player.
In 'The Crystal Trench,' a 1959 episode (based on an A.E.W. Mason story) of the television series Alfred Hitchcock Presents, a similar plot is presented. David Freeman, in his book THE LAST DAYS OF ALFRED HITCHCOCK, writes: "Donald is a young husband who is buried in an avalanche. His widow waits forty years for the snows to shift so she can claim the body. She comes as an old woman, faithful to her memories, and discovers that when her husband died, he was wearing a locket with a picture of another woman."
In several scenes, Geoff (Sir Tom Courtenay) drinks his tea from a Hull City Association Football Club (AFC) mug. Courtenay is the President of the Hull City Official Supporters' Club.
Charlotte Rampling and Sir Tom Courtenay both appeared in Night Train to Lisbon (2013).
