10 Insane Movie Theories You Won't Believe

6. Why We Don't Have Back To The Future Hoverboards

One of the most heartbreaking things about growing up - besides trying to figure out taxes, the constant letters from the Student Loan Company, and realising that your parents definitely had sex once at some point - is discovering that movies lie all the time. Especially films which purport to predict the future, since neither the glittering metropolises or the exciting post-apocalyptic dystopias ever come to fruition. Our world keeps ticking over pretty much as it is, making slow advances towards a progressive society, a life beyond the stars, and hoverboards. Where exactly are our hoverboards? Going by the timeline set in Back To The Future Part II we should be getting them next year, but we've seen neither hide nor hair of technology that even comes close!

Well here we start looking at fan theories which transcend the screen and start intruding on our actual, real lives. See, the reason our expectations have been so unrealistically heightened by Back To The Future isn't because it's a film and, duh, it's just a film €“ there's an actual, in-universe explanation. In the first film we see Marty McFly travel into the past, where he has to ensure his parents get together so history doesn't get all messed up. Along the way, however, he creates a Chuck Berry-shaped time paradox, and also invents the skateboard about two decades too early whilst being chased by Biff and his goons. That set of a butterfly effect where skateboard technology continued to be twenty or so years ahead of what it is in our world, which is why by 2015 in the Back To The Future Universe, they have hoverboards. Doesn't really explain the flying cars or holographic Jaws 19, but great Scott if that's not a fun theory.
