Anyone who loves Leonardo DiCaprio recognizes his iconic role as Jack in 'Titanic.' Decades later, the film is still talked about often -- including Jack's unfortunate demise as Rose refused to share her door with him. OK, so that fan theory has been debunked, so let's not dwell on it.

Instead, consider the fan theory that says Leonardo DiCaprio's character probably didn't even die when the film ended. Sure, fans saw him slip into the icy depths, but let's give this canon a bit of thought.

It's a good thing that Christian Bale lost the role of Jack to Leo, because the fan theory that has viewers saying 'hmmm' depends on the rest of Leo's acting resume, and how the films might just fit together.

Of course, other sad theories abound about Jack and Rose and their unhappy end, but this one's a smidge more positive.

The theory, shared by a fan on Quora -- a self-proclaimed movie connoisseur -- goes like this: Jack doesn't die. Instead, he finds refuge on land and starts his life over again.

Of course, the two possible post-'Titanic' paths assume that it would've been possible for Jack Dawson to wash up on the shore of New York post-near-drowning. For reference, most sources agree that the Titanic sunk at least 1,000 miles from shore. But for the sake of argument, let's say it's possible.

From there, fans can choose from two theories.

One: Jack washed up on shore and used his craftiness to build himself a life of opulence. He falls in love with another girl named after a flower, who's also supposed to marry some rich guy she hates. But in the end, he loses the girl and drowns, in a fateful twist that means he can't escape death after all.

That exact story happened in Leonardo DiCaprio's 2013 film 'The Great Gatsby.' Oh, and the timeline puts Jay Gatsby in Long Island ten years post-Titanic. It all fits, right?!

The second theory suggests that Jack never truly existed; the entire experience aboard the Titanic was a dreamlike state while the actual man in the story was "in limbo." This is the overarching theme in DiCaprio's 2010 film 'Inception.'

What really caps it, says the Quora commenter, is that the Titanic left a port in Ireland called Cobh, which is pronounced the same way as the 'Inception' character of Cobb.

While both of these theories have holes, it's an interesting proposition that filmmakers could connect movies in this way. The theory that some films are entirely dream sequences, or that events didn't really happen but were only daydreams, is a common one when fans begin to pick their favorite media apart.

And who knows -- maybe the film industry is planting these connections on purpose!
