The new Wallace & Gromit movie is good for some laughter and entertainment, but there's a subtle, important parody also at work in the film.

Wallace & Gromit are returning to screens tonight (December 25) with a brand-new Aardman adventure. However, it’s not just the treasured cheese-loving duo that are making a comeback as their new film will also see the highly anticipated return of the villainous chicken penguin Feathers McGraw.
