Science Fact or Cinematic Fact?
In film-making, it is extremely important to create an entertaining story for an audience. One of the most important ways in creating an entertaining story is through the suspension of disbelief. In other words, creating such a captivating story and world that the audience completely forgets that they are sitting on a couch at home or movie theater in downtown San Jose. However, one big way a filmmaker may break an audience’s suspension of disbelief is if the physics in the story world completely disobeying the laws of physics of a realistic world. There are of course exceptions to that rule, like if the story takes place in an imaginary world or is a spoof on physics such as Wild-e-Coyote. But for the sake of this paper, I’m going to point out situations where a film is set in a realistic world but disobeys the laws of physics. Resulting in the suspension of disbelief to be broken. The law I will be focusing on is Newton’s 1st Law of Physics, which is “Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.” The films on trial for breaking this law are “Teenage Mutant Ninja Turtles”, “Speed” and “Live Free and Die Hard”.
In the film, “Teenage Mutant Ninja Turtles” (2014), directed by Jonathan Liebesman, there are countless physics wrong-doings. The worst in my opinion is the scene where the turtles continue fighting while the truck they are riding in is rolling down the mountain side. This description in itself should be enough for a physics expert to cringe and shake their heads in disgust. For, unless the turtles are super men, no one would have survived that entire scene due to the force applied. Megan Fox's character specifically, would have died being flung out of the truck while she reaches out to take a photo. This change in story would have made a much more interesting ending to say the least. There is a lot of external force being applied to each character, however none of them seem to be affected by it. Given the fact that the film had a ton of fighting, this entire scene could easily be cut from the movie without any story points being effected. Adding the actual physics to this scene, of characters getting flung out of the truck, could actually add to the drama and improve the stakes. This is a situation where good physics would improve the story.
In the film “Speed” (1994), directed by Jan de Bont, the story takes place in a realistic functioning setting. A case where physics is broken is in the scene where the bus of people miraculously flies over a break in the road. It is so wrong it’s almost laughable. This is shame because it’s a very serious moment where the hero (Keanu Reeves) faces a life or death situation, yet the moment is completely muddied up by incorrect physics. The road shows no indication of a kicker ramp, which is needed to achieve that kind of a jump. There was simply no motivation for the bus to behave in such a way it did. An object cannot continue moving on a flat line of action when it’s falling and gravity is at play. Either the director needed to show an indication of a sturdy item to act as a kicker ramp or re-think this scenario. Also, showing the bus going a almost 70 miles per hour is redundant to whether or not the bus will fly through the air. 70 miles per hour is not enough speed to defy gravity. This is another situation where accurate physics would actually improve the story.
The final film to be discussed is “Live free or Die Hard” (2007), directed by Len Wiseman. The scene at fault is the helicopter scene where Bruce Willis’s character decides to drive a cop car at a helicopter to make it explode. He then jumps out of the moving vehicle just before it collides. In reality, both characters in this scene would have died. Bruce's character conveniently stopped rolling just before he collides with another object. Given the car was driving at full speed (or almost full speed) he would have been flung out and critically or fatally injured upon impact. Also, the bad guy jumped out of a helicopter showing no effect. His body simply could not withstand the force that was inflicted and his head surely would have hit the pavement after the second fall. Additionally, similar to the bus from “Speed”, the cop car getting flung up toward the height of that helicopter is unrealistic. The car is only shown crashing into the road divider, which magically has the ability to kick the car up and soar through walls without losing speed. Had this obeyed the laws of physics, Bruce’s character would have failed in his epic attempt at defeating the bad guy. In contrast to “Teenage Mutant Ninja Turtles” and “Speed”, I am a little more forgiving of this movie given that it thrives on Bruce’s character doing epic and unrealistic fight scenes. However, I would definitely appreciate the movie more if the filmmakers found a way to keep the action more grounded to laws of physics and gave ample set up and pay off the extraordinary, over the top actions peppered throughout the film.
In conclusion, it’s important for filmmakers to do their research. If a story wants to heighten the stress of a situation, it can not just magically not follow the laws of physics that were established at the beginning of the movie without proper set up. The audience might end up laughing at the intended serious moment or emotionally check out of the movie due to suspension of disbelief being broken. I think it is important to try to work within the confines of reality, it just may result in a better story and a much more happier physics professor.
