1. Ferris Bueller's Day Off – Ferris Bueller Never Existed
According to this theory, Ferris Bueller has been imagined by his friend Cameron the whole movie, causing him to grow as a person. This imaginary Ferris helps Cameron become more courageous, rebellious, and more accepting of the consequences of his own actions. Although this theory kind of ignores all of Ferris' interactions with people separate from Cameron, this is a fun thought and makes for a very cheerful mental breakdown.
2. Star Wars – Darth Jar Jar
Remember that comic relief that everyone hated in Episode 1? Well, what if George Lucas intended for him to have a more sinister role in the series? We know from the movie that he was kicked out of the Gungan civilization underneath Naboo, but we are never told why. Jar Jar puts on the facade of an idiot to fool his new Jedi companions.
Later he becomes a general and a member of the galactic senate, but if you watch his hands during these conversations you will see Jar Jar moving his hands in a “clumsy” way and it can be argued that he is using mind tricks on these individuals promoting him. He can also be seen interacting with Palpatine separate from everyone else but we never actually hear any conversations the two have together. And finally, Jar Jar is the one to lead the vote to end the Senate again moving his hands as if he is manipulating everyone voting on the issue.
3. The Pixar Theory
If you're like me, you like looking into every little detail and have probably noticed all of the Easter Eggs inside of Pixar movies that reference the studio's previous movies. Well, this theory is that all of the movies made by Pixar studios take place in the same cinematic universe but occur at different points on a time line. If we were to put the movies in chronological order, we would start with Brave and see the introduction of magic, which leads to the creation of superhero in The Incredibles, and talking animals and objects in Finding Nemo, Up, Ratatouille, Toy Story, and Cars.
After Cars 2 the Earth began to die from all of the pollution due to the constant use of fossil fuels. Cut to the distant future and we see a desolate Earth in Wall-e until a plant begins to grow, this plant grows to be a tree in A Bugs Life. Thousands of years later animals have begun to mutate and evolved into the monsters that we see in Monsters Inc. and Monster University, and the doors they use to travel through time to the present day.
4. The Matrix trilogy – There is no Escape from the Matrix
The choice of picking a between the red pill or the blue pill was all it took to wake Neo and the others out of the matrix. In the second installment in the trilogy the architect, the creator of the matrix tells us that the first matrix was rejected by humans, because it was designed as a utopia, and that after creating five more versions of the matrix he found a way to fulfill the humans need for free will, by simply presenting them with choices.
Now what if the first choice to was just to make Neo was devised by the matrix and he did not wake up in the real world, but instead, he woke up in a second layer of the matrix, designed for those that reject the current version. This would also explain why Neo's powers continue to work inside the “real” world.
5. The Shining – Kubrick Filmed the Moon Landing
The moon landing has many conspiracy theories surrounding it already, but for those who believe the footage was actually faked, it's not a far jump to say there might be a Hollywood connection. Kubrick was known for using many symbols very cryptically within his films and in the Shining, there are a couple instances he could potentially be bragging about this achievement.
The first is the boy in the movie wears an Apollo 11 sweater. Second is the hotel room which in the book is room 217, but in the movie, Kubrick changed the room number to room 237, and of course, we all know that there are 237 million miles between the Earth and the moon. Still not convinced the government recruited him to make you think humans actually landed on the moon? What if I told you that Kubrick also released 2001: A Space Odyssey in 1968 the year before the moon landing?
