It has been long suggested that the King of Atlantis himself Namor was under the Marvel Studios banner. Some suggested that he is actually at FOX given in the comics his people refereed to him as a "mutant" as well as having strong ties with the Fantastic Four. This proved to be inaccurate given Namor doesn't have the Mutant X gene thus not contractually a Mutant. He simply has pink skin compared to his blue skinned kin.
Then this past summer Marvel Studios head Kevin Feige revealed that Universal Studios of all places owns the rights to Namor. This came out of left field for most fans given we only know the main three studios to own Marvel characters is Marvel Studios, FOX and Sony.
Now Borys Kit of The Hollywood Reporter dropped some details that the King of the Oceans maybe used by Marvel Studios after all!
But at least one thing is wrong: Universal does NOT have the rights to the Sub-Mariner. Marvel has them.

Lest we forget Atlantis was also shown (As well as Wakanda) in 2010's Iron Man II on a S.H.I.E.L.D database screen. As well as the ORACLE company being hinted to in the film as well.
Oh, by the way Marvel if you need an actor I'd go with Zachary Quinto!
