No one who remembers "Stalag 17" will have to guess at the number that's on the front of the hen house, and no veteran of "The Great Escape" will fail to recognize the contours of the farm, complete with barbed wire fencing, barking dogs, and a suspicious Mr. Tweedy checking the locks and muttering about what the chickens are up to.
The kids, for example, probably won't catch the "Stalag 17" references, or "The Great Escape" music during the opening sequence, but they'll love the slapstick antics and tangible animation of the clay heroes.
In fact, the whole structure of the film is drawn from classic World War II prison pictures such as Stalag 17 and The Great Escape; just as the Wallace and Gromit shorts drew on thriller-movie conventions, and indeed as other animated films from The Lion King to A Bug’s Life have traditional structures taken from earlier films.
Most are comparing the film to a spin on the POW pictures of the past, like "The Great Escape" and "Stalag 17," but striking me as more of a chicken-based variation on the Holocaust, "Chicken Run" is set at Mr. and Mrs. Tweedy's England-based farm, and centers on the poultry inhabitants who are constantly making attempts to escape the fenced-in, barbed-wired confinement that they have been restricted to.
