A Grand Day Out is a 1989 British stop-motion animated short film. The first installment in the Wallace & Gromit series, it was directed, animated and co-written by Nick Park at the National Film and Television School in Beaconsfield and Aardman Animations in Bristol. The film centres on eccentric yet good-natured inventor Wallace (voiced by Peter Sallis) and his mute but intelligent pet dog, Gromit, who decide to build a home-made rocket ship and make a trip to the moon in search of cheese.
