British stop-motion characters Wallace and Gromit appeared in which animated film in 1989?

'A Grand Day Out with Wallace and Gromit', later named 'A Grand Day Out', is a British stop-motion animated film released in 1989. It features Wallace, a good-natured, eccentric, cheese-loving inventor, and Gromit, his silent but loyal and intelligent anthropomorphic dog. The film was created by the animator Nick Park. The film premiered on 4th November 1989 at an animation festival at the Arnolfini Gallery in Bristol.

The film tells the comical story of Wallace and Gromit's trip to the moon in a home made rocket to gather cheese, because "everybody knows the moon is made of cheese." After their picnic of cheese, a robot living on the moon clears up their dirty plates, issues a parking ticket for their rocket and tries to prevent them taking the moon's cheese back to Earth.

Park started making the film in 1982, partially supported by the National Film and Television School and Aardman Animations. The animation involved around 1 long ton (1,000 kg) of Plasticine. Park offered British actor Peter Sallis (1921-2007) £50 to voice Wallace, which he readily accepted, giving the character a Yorkshire accent. The film was nominated for the Academy Award for Best Animated Short Film, but it lost to 'Creature Comforts', a film also created by Nick Park.
