The Wrong Trousers - Ending Explained

The film's tension reaches its peak when Gromit discovers Feathers McGraw is a wanted criminal after seeing a "Have you seen this chicken?" poster. The penguin's plan is revealed: he has modified the Techno-Trousers to be remote-controlled. He forces a sleeping Wallace into the museum to steal a diamond, using the trousers' ability to walk on walls. After the heist, a thrilling confrontation occurs where Wallace and Gromit are trapped in a wardrobe. They escape using the trousers and pursue the penguin on a model train. In a legendary climax, Gromit lays down tracks just in time to catch the penguin, who is eventually trapped in a milk bottle. The film ends with the trousers walking into the sunset after being thrown in the bin, suggesting that the cycle of "wrong" technology continues, while Wallace and Gromit reconcile over cheese.

One common alternative reading is as a critique of the industrialization of the domestic sphere, where the Techno-Trousers represent the intrusion of labor-saving devices that actually complicate life and erode personal relationships. Critics have also noted a Queer coding interpretation in the domestic jealousy between Gromit and the penguin, viewing the conflict as a battle for Wallace's primary affection. Another perspective frames the film as a post-modern Noir, using the tropes of Alfred Hitchcock and film noir to elevate a simple children's story into a sophisticated exploration of psychological manipulation and urban dread.
