Re: Thor 2 -Movie Discussion, News, Interviews, Pics till release 2013
Universal were supposed to be doing a Sub-Mariner movie that was described as "like Star Wars, but underwater".
since they signed the rights to Hulk back to Marvel, i'd imagine Namor's reverted.
I think it's very likely that the rights to Namor have reverted to Marvel Studios. In April 2010, Kevin Feige told Collider
that "Universal doesn't have anything."
