There is nothing more fascinating than the Cloverfield universe.

When last year’s 10 Cloverfield Lane was released, many fans were kind of bummed that it didn’t seem to really have much of anything to do with the 2008 found footage monster movie, Cloverfield. And on the surface, it really doesn’t. Sure, alien monsters do show up in the final act, turning the contained thriller into a big sci-fi movie, but aside from little things here and there, what the hell do the two actually have to do with one another? Well, in order to answer that question, one needs to examine the incredible wealth of ARG material that exists for both films.

But don’t worry. One fan has done all the hard work for us.

The YouTube channel Inside a Mind is one of the most fascinating you’ll ever come across, mostly devoted to wacky fan theories that’ll have you looking at various pieces of entertainment in a whole new light. But the 10 Cloverfield Lane theory video isn’t so much a “fan theory” as it is an in-depth examination of the existing ARG (Alternate Reality Game) that J.J. Abrams and his team put out there in the world. When you closely examine all of it, and put those various puzzle pieces together, you can create a story that is more fully realized than anything you saw on screen.

Now I’d rather you watch the video for yourself to find out all the secrets of this universe, but one thing I will mention is that the analysis most definitely ties Cloverfield and 10 Cloverfield Lane together in a way that makes total sense. The films, which take place nearly a decade apart, most definitely exist in the same world, so if you were thinking Abrams is just going around carelessly slapping the Cloverfield title on movies and not bothering to actually make sense of what he’s doing… think again. This shit is masterful, and the actual movies have only scratched the surface.

When you’ve got 20-minutes to spare, devote your full attention to this riveting video.
