After apologising to Ray (Dean Andrews), Alex (Keeley Hawes) says "Clunk-click, every trip." This was the slogan used in a series of UK public information films fronted by Jimmy Savile commencing in 1972 which were sponsored by 'The Royal Society for the Prevention of Accidents' to encourage the use of car seat belts (also at the time known as safety belts). Ray used the same expression in Series 1: Episode 8 of Life on Mars (2006).

They Died With Their Boots On upstairs was a spaghetti western released in 1978 directed by Lucio Fulci and is about a man who avenges the murder of his father, originally released in Italy as Silver Saddle (1978). It is also the title of the 1941 western bio-pic, They Died with Their Boots On (1941), of General Custer that ends with the Battle of the Little Bighorn, it starred Errol Flynn and Olivia de Havilland and was directed by Raoul Walsh. At one point Custer (Flynn) promises his troops he will teach them "to endure and die with their boots on".
