• The radio station where Robert is a disc jockey was based on the United Biscuits Network, which broadcast to factories owned by United Biscuits.^{[citation needed]}
• There are a number of references to the films of Wim Wenders, who is credited as associate producer. Early in the film, a copy of Patricia Highsmith's Ripley's Game is seen on a table in Robert's flat. Wenders 1977 film The American Friend is based on this novel. The character played by Sting is called Just Like Eddie. In Wender's film Kings of the Road, two of the characters sing along to the song Just Like Eddie by Heinz. And Lisa Kreuzer, who plays Ingrid, is looking for her daughter Alice. Kreuzer was married to Wenders for several years, and was in several of his films, notably Alice in the Cities.
