Ingenious author and director Nick Park, helped in this film by Peter Lord, has already been awarded three Oscars for his shorts Creature Comforts (1990), The Wrong Trousers (1993) and A Close Shave (1995), produced by Aardman and included in Wallace & Gromit, an anthology of masterpieces whose protagonists are made of plasticine. This is his first animated full length film, finished after three and a half years' work in a huge hangar built by Steven Spielberg's Dreamworks on purpose.
