There have been plenty of rumors about "Batman V Superman: Dawn of Justice," some more believable than others. Sure, that one Instagram picture makes it look like Jesse Eisenberg is wearing a wig, and I buy that Scoot McNairy is wearing green socks because he lost his legs.

But this "new" rumor about Aquaman's connection to "Man of Steel"? I'm not so sure.

The story goes that during the events of "Man of Steel," Aquaman -- who is a "buff Hawaiian guy, covered in tribal tattoos" according to The Wrap's Jeff Sneider -- sees the oil rig going down and sends in these two whales to save the unconscious Superman.

Taking the theory at face value, there's certainly some room for this to be true. The whales have no real reason for being there, other than looking cool. (And it's not like Zack Snyder would put something in a movie just because it looked cool... Wait.) And the oil company that owns the drill, Merrevale, is a name that's popped up more than once in Aquaman comics. It's conceivable that this story could be true.

Then you look at the rest of the information about the theory.

The line connecting Aquaman to the humpback whales in "Man of Steel" is essentially as old as the movie itself. (Here's an article about the theory that MoviePilot published ten days after "Man of Steel" hit theaters.) It was an idea that fans jumped on immediately, sensing that Snyder and writer David S. Goyer were starting to build a larger, interconnected DC cinematic universe, à la Marvel Studios.

The only reason that more people are talking more about the theory now is that Sneider repeated it as a small scoop on the "Meet the Movie Press" podcast, but you should really listen to the whole story, starting at the 29:45 mark.

So Sneider got his intel by eavesdropping on an "older gentleman" who claimed to work with Zack Snyder on "Batman V Superman."

Is it possible that the guy Sneider overheard actually knows what he's talking about? Sure. Is it also possible that he's full of it and just repeating a widely circulated fan rumor, and that in overhearing, Sneider couldn't grasp the full context of the conversation or properly judge its credibility? Definitely.

I can't say one way or the other which is more likely, but I have to think that both options need to be considered. Is there evidence to support the theory? Sure, but I think before we all get our hearts set on an Aquaman-centric flashback sequence in "Batman V Superman," we should check our expectations a bit.

"Batman V Superman: Dawn of Justice" opens in theaters on March 25, 2016.
