This film manages to refer to every single Wallace & Gromit adventure, even the upcoming ones. When Gromit is in jail, we see a crescent moon through the window, referring to their trip to the Moon in A Grand Day Out (1989). In the same scene, 'Feathers Was Ere' is written on the wall. He was the villain of The Wrong Trousers (1993). Gromit's reading a book published by Penguin, and Feathers was a penguin. When Wallace thinks they have rats, he thinks about calling in pest control. He and Gromit become pest controllers in The Curse of the Were-Rabbit (2005). Gromit sees a poster for Baker Bob outside Wendoline's wool shop. Baker Bob would get murdered in A Matter of Loaf and Death (2008).
In a radio interview, director Nick Park said that Wallace's references to Wensleydale cheese in this film unintentionally saved a small British cheese-maker from bankruptcy. Interest in the cheese was sparked by the film, and one of the few makers of Wensleydale suddenly found itself with numerous requests for it, thereby saving it from financial ruin.
When Preston is reading the paper, one of the headlines talks of an Oscar winner. This is probably a reference to The Wrong Trousers (1993), which won the Oscar for Best Animated Short. This film would also win the Oscar that year.
In 1995, when this film was first aired on British TV, because of their huge popularity, Wallace and Gromit became BBC2's Christmas mascots and co-starred with a live 2 in a small line of "sting" trailers and idents.
The motorcycle used by Wallace and Gromit is a 200cc Triumph Tiger Cub which was not normally used with a sidecar. A large topiary model of the pair in their vehicle was on display in Solihull near Triumph's old factory in Meriden.
