Trivia

The filmmakers of Toy Story (1995) have indicated in interviews that the moving-van chase scene at the end of the film was partially inspired by the toy train chase scene from this film. The Pixar animators considered the toy train sequence to have set a standard for action which they had to surpass in this full-length computer animated film.

In an effort to get Gromit out of the house, the penguin plays very loud music. One tune is "How Much is That Doggie in the Window?" and another is "Tie a Yellow Ribbon Round the Ole Oak Tree" which indicates that he's just been released from prison. The first tune was since been replaced by a second playing of Yellow Ribbon due to an issue with licensing. Gromit's Birthday Card no longer plays 'Happy Birthday' for the same reason and has been replaced by 'For He's A Jolly Good Fellow'.

When Gromit is reading the newspaper at the café, one of the headlines is "Dog Reads Paper".

In one scene, Gromit is reading "The Republic" by Pluto. The actual author is Plato; Pluto is Mickey Mouse's dog. Mickey himself is briefly visible in a photograph on the mantelpiece during the breakfast scene.

The headline of Gromit's paper at the beginning reads "Moon Cheese Shares Soar". Mostly likely a reference to Wallace & Gromit: A Grand Day Out (1989) the original W&G short, in which Wallace and Gromit go to the moon in search of cheese. Another reference includes wall art resembling three fish but which are actually three spaceships from Grand Day Out.
