6. Chicken Run
Most of the time childrens films decide to humanise something that wouldnt usually speak for the benefit of the movie. The things brought to life and suddenly allowed to talk are multiple and varied think Remy the rat in Ratatouille, Flick the ant in a Bugs Life or even objects from around the castle in Beauty and Beast. Usually, this doesnt mean too much, as the magical creatures are confined to their own world and even when their lives are tied up with humanity, humans either tend to be distant to the actual plot or buffoonish and friendly. Yet this isnt the case in Chicken Run, or as its otherwise known, the film which inspired a generation of vegetarians. The humans in Chicken Run are malicious, keeping the chickens against their will and under guard with dogs. For a while, this is good fodder for a fun plot, and Chicken Run duly complies, filling itself with The Great Escape motifs. That would be fine if that's all it did, but then the film throws a curveball and shows you exactly whats at stake. Namely, it decapitates a chicken. Up until now, you knew that this was an egg farm there was always vague threats of what would happen if the chickens didnt lay enough eggs, but then the film decides to make that threat, very explicit, very quickly. Granted, you dont actually see the chicken die but the montage alone complete with an axe coming down was enough to be pretty disturbing for anyone, never mind kids. It sets you up for when the main antagonist Mrs. Tweedy goes full homicide later, creating a pretty effective advert for vegetarianism. After all, who wants to eat the adorable chickens now?
