Science Fact or Cinematic Fiction



            The art of filmmaking is beloved for its ability to tell a story grounded in realism with a dash of something extraordinary. That being said, there are some aspects of this visual art form that often, sometimes without intention, push the limits of what is realistically possible, even going so far as to break the laws of physics themselves! One example of this is how people and objects fail to respond with the proper type of reaction to opposing forces. While this can be attributed to a production oversight, it is also used a necessary means to project a specific type of emotional response or feeling. Whatever the case may be, films have smashed the action/reaction rule of physics in various ways.
In Disney’s 1997 animated feature film Hercules tells the story of the titular hero with incomparable strength from Greek mythology. There is a critical scene towards the end of the film where Hercules fights one of the titans that poignantly illustrates the fallacious use of the action/reaction rule. The cyclops is already portrayed as a monumentally huge, incredibly strong creature that can level buildings and smash stone with little to no effort whatsoever. Hercules, weakened for the time being and pointedly mortal, withstands the cyclops blows with nothing more than some bruising despite being kicked, thrown, and bounced around by the titan. Although Hercules has some physical reactions during the fight, such as stumbling when prodded, flattening against a smashed wall, and collapsing after being slammed into the ground, they are severe understatements as to what would actual happen if this scenario were to occur in the real world. At another point in the scene, the hero is even lifted by the enormous titan at one point from the ground all the way up to his single-eyed head, but Hercules displays little to no visible reaction to the forces that he would experience while moving such a huge distance so quickly. The fight wraps up with Hercules using a regular-sized rope to entangle the titan’s gargantuan legs and pull him to the ground and over a cliff. Not only does the cyclops' inability to bust through a relatively tiny strand of rope contradict his previously-displayed strength, but also Hercules would not be able to pull the cyclops down to the ground without his iconic power. Although enjoyable, the scene is riddled with all kinds of completely inaccurate interpretations of how the laws of action/reaction work between two characters of hugely different sizes.
Warner Brother’s third installment of the Harry Potter series, The Prisoner of Azkaban (2004), is filled with a wonderful amount of impossible, awe-inspiring physics, but there is one scene in particular that has some delightfully peculiar yet entirely incorrect interactions with the action/reaction rule. The Knight Bus, a magical triple-decked public transportation vehicle with the ability to dodge the laws of physics just as smoothly as it navigates the Britain's traffic patterns, is filled with three-stories worth of inconsistent physics fallacies. Harry is repeatedly shown to react strongly to the sudden accelerations and extremely exaggerated stops, yet the other characters riding along show little to no response to the immense amount of forces that should be altering their weight and center of gravity. Despite being filled with rolling beds for long-distance travelers, these wheeled sleeping arrangements move with a temperamental consistency, only responding with the bare minimum amount of motion to prove that they are not simply nailed to the floor. Perhaps the hardest sell on the bizarrely inconsistent laws of action/reaction so laxly imposed on this bus is the mouthy co-pilot, a shrunken head dangling from a string, is not influenced by the bus’s motion at all! As egregious as this particular error is, the most consistent rule break remains the reaction to the centripetal and centrifugal forces of the vehicle—although the opportunity to impose these forces among the characters riding onboard is abundant, it is strangely non-existent.
Perhaps the film that tackles the action/reaction law with the greatest inaccuracy is another Disney animated film, The Emperor’s New Groove (2000). The heart-warming friendship that blossoms between Kuzco and Pacha is founded upon a sea of physics lies as the characters snap through the laws of action/reaction as quickly as the rope and wood bridge upon which they were standing. They not only have an unusual amount of unrealistic hang time in the air before eventually succumbing to the pull of gravity’s forces, the bridge beneath them also breaks with a sluggish irreverence to the laws of physics. What happens next sets the stage for one of the most memorable parts of the film—the soon-to-be-buddies are crammed at the bottom of two tight opposing cliff faces and work together to return to the top by pushing up against each other’s back to walk up the walls. Pacha very clearly weighs more than Kuzco, but the latter is not shown to compensate for this by pushing harder against both Pacha and the cliff—he appears much more neutral here than he should in this scenario. There are also a couple instances where Kuzco physically panics and without a questionable doubt fails to provide the same abysmal amount of force previously needed to support himself and Pacha. As inaccurate as that is, the two characters eventually return to solid ground by impossibly riding a stream of real, flying bats—it practically goes without saying that there would be nowhere near enough action to support that type of a reaction! To wrap up the scene, Kuzco catches Pacha in mid-air before swinging him to safety after the patch of ground he was standing on crumbles into the alligator-river infested river below. Again, this series of actions are presented in such a way that they fail to justify the amount of weight Kuzco would have to carry, if he could at all!
As plentiful as these examples of incorrect representations of the action/reaction rule, they only scratch the surface of physics fallacies found in these films alone. Even though they break the rules of reality quite generously, that does not necessarily mean it is a bad thing. As shown in Hercules, it is a perfect example of how the hero can get out of a situation that is literally impossible so that the audience can still cheer for him. In Harry Potter and the Prisoner of Azkaban, the Knight Bus scene still conveys the proper amount of quirkiness needed without creating an overly-stimulating, cluttered scene. The comedy of The Emperor’s New Groove would be greatly dampened (perhaps even non-existent) if it was bound to the realism of the actual world.  Clearly, the act of bending, breaking, or completely demolishing the rules of physics certainly has the ability to add even more excitement and fantastic flare than it detracts.
