With Marvel's Inhumans series set to begin filming soon, fans are anxious to see which characters could be appearing. It's been confirmed that Medusa and Black Bolt will be around, but there's a horde of other characters in the Inhumans lore.

This includes one of Marvel's oldest characters, Namor: The Sub-Mariner

Namor The Sub-Mariner, originally called the first mutant, was recently revealed as a possible Inhuman. After the events of Secret Wars, Namor was no longer considered a mutant. Joe Quesada was then working on a series called Namor: The First Inhuman. Since Marvel Studios has the rights to Namor, but not to mutants, they had to make the transition somehow. A new rumor suggests that the character could finally be swimming into the MCU, but it's nothing more than a grumbling at this point.

Reel News Hawaii, a film source on the island, reported that there were rumors circulating that both Namor and Aquaman would be filming in the waters of Hawaii this year. The source made it sound like there would be a Namor movie, but that's not in Marvel's plans in the near future. What is true though, is Marvel's Inhumans series will be filming in Hawaii very soon.

There's buzz around the island that two rival productions could be swimming on our waters. "Aquaman" & "Submariner". Fingers crossed! pic.twitter.com/1WLbZkWJAN — Reel News Hawaii (@reelnewshawaii) February 15, 2017
