The Most Outrageous Fan Theories About Sci-Fi Movies

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.

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.

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. 

If you saw the original Mad Max movies, then you might remember the Feral Kid from the second film. This theory states that that kid grows up to be Mad Max, in moniker at least. The fact that the modern Mad Max has a very familiar looking music box and grunts and growls like the kid did, adds some credibility to this idea.

It's also supported by the fact that for the first time, Max Rockatansky suddenly doesn't look like Mel Gibson.

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.

Early in the first Jurassic Park film, Doctor Grant berates some random kid about how velociraptors deserve respect on account of their ability to eviscerate their prey in style. Fast-forward to Jurassic World, and Owen, who is about the age that kid would be more than 20 years later, respects raptors more than anybody.

There's not much else to this theory, but it's interesting nonetheless.
