For some fans, their favorite sci-fi movies go much deeper than what happens onscreen. From The Matrix to Mad Max: Fury Road, just about every great science fiction film has at least one or two compelling fan theories. Sometimes these theories are debunked or confirmed by actors, directors, or even sequels, but more often than not, whether or not these theories are really true remains mysterious.
For science fiction fan theories to be respected and considered, they have to be supported by considerable evidence. There's usually something out of place or seemingly random that is, in fact, crucial to the underlying theory. Some sci-fi fan theories are so good, that it seems as if they must be true. Others leave the fan-bases arguing endlessly.
One way or the other, sci-fi fan theories are some of the best pop-culture theories out there. Some of them have completely changed the way we see movies and have put into question elements that were once considered canonical.Check out this list of outrageous fan theories about your favorite sci-fi films and vote up the ones you think are the most beyond outrageous.
Marty McFly Died in Back to the Future Part II
This theory suggests that Marty actually died a horrible death in Back to the Future Part II. Specifically, Marty was run over by Biff while he was being chased on his hoverboard. So when Doc Brown swoops in with incredible timing to save Marty, that's actually Doc having gone back in time to save his teenage compatriot.
The theory also suggests that Doc might do this frequently and that Marty might actually die several times over the course of the trilogy, only to be "saved" by Doc traveling back before each of his untimely demises.
Indiana Jones Is Basically Unkillable
Remember in the beginning of Kingdom of the Crystal Skull when Jones survives a nuclear blast by hiding inside a refrigerator? If you do, you probably also remember asking, "How?" One Redditor has an idea: drinking from the Holy Grail in Indiana Jones and the Last Crusade years before imbued Indy with supernatural resilience.
If this theory's to be believed, then drinking from the chalice didn't make Indy immortal, but it did give him some extra mileage.
Cobb's Totem was His Ring, Not the Top
In Inception, DiCaprio's character Cobb has a totem so that he can tell if he is in the real world and not the dream world. The audience assumes that it is the top he is frequently seen spinning. In reality though, it is his ring, according to the theory. Cobb always has his ring on in the dream world but never does in the real world.
This also means that the ambiguous ending is summed up when you see that Cobb isn't wearing his ring in that scene.
Stan Lee Is Uatu the Watcher
Uatu is a time-traveling, omnipotent, immortal superbeing in Marvel Comics. This particular theory suggests that the reason Stan Lee keeps popping up in nearly every Marvel movie ever is because he is actually Uatu, quietly keeping an eye on the happenings of the universe.
Of course there are a few reasons that this is unlikely, but it does explain why Lee is present whenever and where ever something important happens in the Marvel cinematic universe.
