11. Andy's parents are divorcing
In the original Toy Story Andy's family are seen inexplicably moving house, and throughout the whole movie, his dad is nowhere to be seen. Why? Well if you pay close attention, the answer's obvious. Andy's parents have separated, and now Andy's mother, now a single parent, has decided to move the reduced family into a smaller house. It might sound depressing: but there's plenty of evidence backing it up: Andy's dad is never mentioned, and there are no pictures of him in the house. Andy's mum also neglects to wear a wedding ring, and Andy doesn't appear to have many friends for a kid his age. Is this because he's a lonely child pining for a missing father, who retreats into fantasy worlds and is unusually invested in toys because there's something missing in his family life?
12. The Vision wasn't actually worthy of Mjolnir
In Avengers: Age of Ultron, a pivotal scene is when The Vision, an android created by Tony Stark and Bruce Banner using the power of an infinity stone, lifts Thor's hammer Mjolnir. In the legends of Asgard it's stated that only Thor himself is worthy of wielding the hammer - and in an earlier scene the other Avengers attempt it and can't move it an inch. When the Vision hefts the weapon it seems to prove that he's as trustworthy as Thor. But is he really? Or is this just a con by Vision in order to get into the gang's good books? Remember that at the end of the film Tony seems to realise that machine can lift Mjolnir: if it was resting on an elevator then the lift could raise it, and the Quinjet is able to carry the hammer through the air. Therefore, one can infer that machines, and therefore The Vision, are able to lift the hammer no problem. Vision knew this, but gambled that the other Avengers didn't, and thus tricked them at a crucial moment in order to enter into their confidence.
13. The true meaning of 42
In The Hitchhiker's Guide to the Galaxy, the supercomputer Deep Thought is built by a race of hyper-intelligent alien beings to determine the answer to "life, the universe, and everything." Deep Thought determines that the answer is, somewhat anticlimactically, "42." It sounds like a joke, but is there more to this answer? Douglas Adams was an unabashed computer nerd and knew a heck of a lot about programming language and coding. In programming, an asterisk is commonly used to translate as"whatever you want it to be". In ASCII language, the most basic computer software, "42" is the designation for an asterisk. A computer, Deep Thought, was asked what the true meaning of life was. It answered as a computer would. 42 = "anything you want it to be." Genius.
14. Finding Nemo deals with the five stages of grief
This theory claims that the entirety of Finding Nemo is an elaborate metaphor for Marlin (played by Albert Brooks) coming to terms with the death of his wife at the beginning of the movie. throughout the course of the narrative, we see Marlin go through all five stages of the Kübler-Ross model of grief. First Marlin experiences denial: trying to keep his son safe at all times and ignoring reality, anger when he loses Nemo again and realises that he can't shield him from harm, bargaining when he accepts Dory's help even though he doesn't particularly like her, depression when he thinks that Nemo is dead, and finally acceptance when he realises that he has to move on and let Nemo enjoy his life. What's extra significant is that Marlin has partnered with Dory for the duration of the film: a fish who has no short-term memory but is happy and content. Through Dory Marlin learns to stop obsessing with the past and move on from his trauma.
15. The Asteroid field is a destroyed planet
One of the most exciting sequences in Empire Strikes Back is the scene in which Han pilots the Millennium Falcon through a deadly asteroid field in order to evade Darth Vader. In this sequence, Han weaves through a number of gigantic boulders, which are clustered very close together. However, in real life, the asteroids in asteroid fields are many, many miles apart, not clustered close to one another as they appear to be in ESB. Is this artistic license? Not necessarily. Maybe this isn't a conventional asteroid field at all, but actually, a planet that was destroyed to test the Death Star? This isn't random space debris - this is rubble from a planet the Empire destroy when testing their super-weapon! It could even be the remains of Leia's home planet, Alderaan
As cool as most of these theories are, the majority of them will never be confirmed by their creators and will languish in cyberspace perpetually, being circulated and picked by cinephiles ad nauseum. However, every once in a while, a popular fan theory gains enough traction to actually be confirmed by the moviemakers, such as this theory which connects Disney's Frozen with Tarzan.
