The Laws of Physics in Despicable Me - Term Paper

“Artists use lies to tell the truth. Yes, I created a lie. But because you believed it, you found something true about yourself.”  
 
Alan Moore

This quote by the writer of the vastly popular graphic novel, V for Vendetta, rings true for all imagined worlds.  Having an element of truth is vital when telling a story.  The physics that exists in an animated world is just as much of a story-telling device as any other part of the film.  When altered physical laws that exist in animation remain consistent and retain some attributes of our own known laws, they can add comedy and emotion to a scene.  The audience will not only accept the altered laws, but may subconsciously invent reasons for why they are acceptable.  One prime example of this effect can occur while watching the Universal Pictures film, Despicable Me.

There are a few theories that the audience must accept in order to relate to the world of Despicable Me. First, there are extraordinary materials that exist which have not been discovered in our world.  Second, the stylization of the characters and machines make impossible maneuvers and mechanical inaccuracies conceivable.  And third, concepts of gravity, mass, height, and volume have lots of fluidity and dimensions.

In the first scene of Despicable Me, a tour bus making its way over some sand dunes stops abruptly in front of the pyramids.  In the natural world there would not be enough traction on such loose sand.  This sets the mood for the film because at this moment the audience can sense that the laws of physics are not the same as ours.  It may be assumed that advanced materials exist and that extraordinary tires are available to the bus drivers of this world.
In that same scene, a child falls off of a ramp onto a giant inflatable pyramid.  Upon contact, the kid sinks deep into the pyramid and is then launched very high into the air.  The kinetic energy to potential energy is clearly off.  The only way for this sequence to be mildly accepted is if the pyramid were made of a highly elastic extraordinary material. 
Gru has many inventions that would not be possible in our world.  His freeze ray is capable of making icicles out of living things without harming them.  In fact, it seems that people who get frozen have no problem getting unfrozen.  If a living person were to be frozen in that manner, their blood would coagulate and they would die. So here we have to assume that the material freezing the characters is extraordinary-perhaps containing a harmless fictional chemical that mimics our own chemicals that are used in cryogenics. 
Gru’s platform structure is another case for speculation. The feeble support beams that lift the weight of his platform could not hold up without being made of an advanced metal.
And finally, the most curious of extraordinary materials in Despicable Me is Vector’s soft, plastic-looking bubble helmet that floats around and doesn't burst in the vacuum of space!  But its movement complements that of its wearer, meant to enhance the character’s charm.


The next theory is that because the characters and objects in Despicable Me are so stylized and often made up of extraordinary materials, they are capable of impossible maneuvers and prone to mechanical inaccuracies.   

The first example of this is when a minion is manning the guns equipped aboard Gru’s plane and is shaking with each shot.  This reaction would not occur with the way the controls are configured.  However, it adds comedic effect to the scene, which the minions are meant to add. 
In a later scene, Gru takes the girls to a theme park on the pier.  While riding the roller coaster, the car accelerates while going up a hill.  This is not how roller coasters work, but I can imagine that this was for comedic effect since Gru is so obviously unsettled by the ride.
At one point, Gru becomes frozen from the head-down by means of his aforementioned freeze ray.  He then proceeds to waddle around, contained by a giant ice-cube.  Even if we accept that the freezing component is harmless to the body, the act of waddling around the room would still be impossible since Gur has no range of motion.
Dr. Nefario is Gru’s elderly partner who rides around on an electric scooter.  At one point he accelerates and his scooter makes the vroom sound of an internal combustion engine exhaust.  This is clearly for comedic effect, but inaccurate in our world.
Toward the end of the film, Gru is being attacked by Vector who sends heat seeking missiles to destroy him.  In a slow motion scene, Gru effortlessly jumps from missile to missile to avoid being hit.  But Vector is not finished (nor baffled by his opponent’s sudden acquirement of superpowers.) He launches a great white shark at Gru who punches the creature with such a force that it flies in the other direction.  Great whites weigh 5,000 lbs on average, whereas American human males weigh about 177.9 lbs (Gru was apparently raised in Albuquerque, New Mexico, despite what may be inferred about his accent.)   That means, realistically, the shark would weigh about 28x that of Gru, who would therefore not be capable of holding his ground when contact was made with the airborne shark. Even if the shark weighed only about 5x Gru’s weight, he would still travel in the direction of the shark due to inertia.  But this brings me to my next point because the great white really does appear to be only about 5x Gru’s weight in the film.


The third theory to be considered is that concepts of gravity, mass, height, and volume have lots of fluidity and dimensions in Despicable Me

Approximate Jump Height of an Average Person as a Function of Surface Gravity
The most obvious example of this is in the dream-like sequences that Gru has. For example when the girls are running with the shrink ray there is a shift in gravity.  They have a much higher hang time and appear to be less affected by gravity.  Also, on Earth, it is possible to jump about 2ft in the air from a standing position. Though not quite the height of a moon jump (up to 22ft), the girls do get about 4ft in the air with each skip. 
So perhaps the surface gravity becomes closer to that of Mars (0.38), on which you can get up to a 9ft jump. (For reference: Earth’s surface gravity is 1 and the moon’s is 0.165). (Wikipedia).  But these are dream-like sequences and so they are more easily accepted than other gravitational shifts throughout the movie.  

In one scene, a minion consumes an anti-gravity serum and begins to float.  He starts off slowly and then accelerates upward, flying out of sight.  This could be explained by either looseness with the concept of gravity or by extraordinary materials – a serum that causes you to become exponentially less affected by gravitational pull.
The Minions seem to be the least affected by the laws of physics, which is not inconceivable since they are an abnormality of biology to begin with.  They seem to constantly change size depending on the scene.  It is not entirely noticeable and is clearly a tactic that the animators used to get better compositions for story-telling. 
In the grocery store scene, a minion shakes a two liter soda bottle, opens it, and the pressure released causes it to fly in the opposite direction, pulling the much larger minion with it. The minions are the most comical element of the film and therefore the audience gives them their scenes the most lenience as far as physics is concerned.
The weapons that exist in the film are not only made up of extraordinary materials, but also have physical characteristics that could not be explained by their composition.  At the pier, Gru pulls a small gun out of his coat that, upon activation, reveals much larger components.  Similarly, Vector’s squid launcher could not contain multiple rounds of squid ammunition, and especially not living ones if they were to be compressed into the small clip (or whatever holds the cephalopodic projectiles).  The dimensions of mass are stretched in these cases for a surprise factor, and it definitely succeeds in being hilarious.


There are some inconsistencies in the film that mostly are done for story-telling purposes as well as to prevent shock on the part of the audience.  



Toward the beginning of the film, Gru’s plane gets shrunk by Vector.  He and the minions are the only things aboard that do not get any smaller, and furthermore, they are not crushed by their shrinking surroundings.  The latter part is easy to explain: Despicable Me is an animated kid’s film in which the characters do not die painful deaths. But the part about the minions and Gru not shrinking with the plane is a troubling case. One could argue that perhaps the shrink ray does not shrink living things. However, their clothes also remain fitting, and in a later scene, a minion is shrunk by that same device.  It is understandable that this inconsistency should happen since the introduction of the shrink ray is a vital part of the story, but Gru and the minons getting back to normal size would cause a far worse inconsistency.  However, this is one of the most notably distracting parts of the film.

At the end of Despicable Me, there is smaller distraction, but equally confusing to the last. In Vector's plane, the shrunken moon starts to grow back to its normal size.  At about the size of a softball, it crushes a mug, but at the point where it grows larger than Vector and rolls over him (multiple times, I might add), it does not kill him. I suppose this could go under advanced materials too in the case of extraordinary flesh and bone (or maybe the mug was extraordinarily fragile.)  There could be an explanation using any of the three theories listed above, but the scene and concept of the shrink ray remain a mystery.  It is easy to say that the writers should have fixed these issues, but I think that providing explanations of how the shrink ray and other things function would detract from the story more so than just leaving them a little inconsistent.



Despicable Me is the story of a supervillain who adopts three orphan girls to aid in his plot of stealing the moon. This summary alone would tell you that the laws of physics are not followed in the movie.  But with this particular plot, pushing physics beyond the limits of the natural world would be the only way to succeed in making a fantastic movie; and that can only be achieved through animation.  Exaggeration is the backbone of animation. Whether it is exaggeration of character, story, or physical movement, it is the reason why animation has retained any relevance when such great technological advancements have been made in the film industry.  The challenge of creating a world with physical laws that deviate from our own is deciding which things must remain the same in order for the film to be relatable to its audience.  The world of Despicable Me is very unlike our own, and yet it is so easy to relate to the story and its characters (even the little yellow freaks of nature).  Just as Alan Moore puts it, believing in a lie can teach you something true about yourself.

Term Paper Outline: Despicable Me Analysis

Intro
Animated Feature Film:  Despicable Me
Thesis: In the universe of Despicable Me, physics does not reflect the principles of the natural world.

Body
1.  Advanced Materials; for certain events to occur, extraordinary materials would have to exist that do not in the known world
-1st scene: bus stops abruptly on sand dune - but shouldn't be enough traction - assuming extraordinary tires
-amount of rebound on the inflatable pyramid - potential energy to kinetic energy off (launches kid) - must be   highly elastic material
-Structure in Gru's lab that lifts him to the ceiling in front of the moon - feeble and wouldn't support platform -    unless, of course it is an extraordinary material.
-In the vacuum of space Vector's soft plastic bubble helmet would pop - must be some crazy material not  known to man

2. Impossible Maneuvers and Inaccuracies
-When the minion aboard Gru's plane is shooting at Vector's plane using the plane's weapons, the control is shaking with each shot - wouldn't happen
-When Gru and the girls are riding roller coasters on the pier, the roller coaster accelerates while going up hill 
 not how roller coasters work
-Gru gets frozen from the head down but has the ability to waddle around in the giant ice cube
-Sound in space- nope
-Dr. Nafario's electric scooter makes a vroom sound - wouldn't make the sound of an internal combustion  exhaust.
-Heat-seeking missiles are heading toward Gru, he simply jumps on them to avoid being hit.
-Next, Gru punches a launched shark which then flies in the other direction - The shark would weigh at least    3x what Gru weighs so he would not remain in place.
-Gru's arm would be ripped off when he is caught mid free-fall by hanging minions.

3. Concepts of gravity, mass, height, and volume have lots of fluidity & dimensions
-Gravity changes in some dream-like sequences - ex the girls running with the shrink ray - they are sort of    floating
-minions seem to change sides between scenes
-anti-gravity serum that minion drinks: he starts to float off and then accelerates upward, flying away
-minion shakes a 2 liter soda bottle in the store, opens it, and then it flies in the opposite direction, pulling the  minion with it.
-small guns and squid launcher conceal much larger components (and squids) in no visible compartment.

Inconsistencies
-The shrink ray shrinks Gru's plane and its contents, but not Gru or the minions - this could be explained if the  shrink ray could only shrink inanimate objects, but a minion is later shrunk and so it is inconsistent.
-In Vector's plane, the shrunken moon starts to grow - at about the size of a softball, it crushes a mug, but  when it is bigger than Vector it does not kill him...I suppose this could go under advanced materials too in  the  case of extraordinary flesh and bone.

Conclusion
-In Despicable Me, the laws of physics are pushed to make for comedic effect and excitement. Although some inconsistencies seem less intentional, there is enough deviation from real world physics that the film feels like a different world, and makes it entertaining to its audience.
