#5 Superman vs Kaiju
And then there's the Horn of Proteus. Namor pre-dates the Fantastic Four, but returned to prominence in that book's pages at a time when Marvel was bridging the gap between its 1950s monster comics and its 1960s superhero comics. The revived Namor brought with him a horn that could summon giant underwater monsters, and thus the mythology of Marvel's Atlantis includes its own kaiju.
Now, Pacific Rim was a bigger hit overseas than in the US, and giant monster movies have a slightly spotty box office history, but surely no-one could deny the appeal of a movie that pairs superheroes with giant monsters? Heck, the Avengers movie tried it, and those Chitauri space worms were nowhere near as cool as a Kirbyesque whale-beast, or a scaly seven-headed elder god.
Namor is basically a sexy Hulk who wrestles Godzillas. What's not to love?
Unfortunately there is one reason Universal should not make a Namor movie...
#6 Time is Running Out
Last year Marvel's Chief Creative Officer Joe Quesada remarked that he thought the rights to Namor had already reverted to Marvel. He was wrong. It seems reasonable to infer that the rights may revert back soon, in which case Marvel might integrate Namor into its cinematic universe just as it plans to do with the Daredevil TV show on Netflix.
I would prefer a unified Marvel universe. I want Namor to be part of the same world as the Avengers, side-by-side with Thor and Iron Man and, one day, Dr Strange. If Universal won't hurry up and make a Namor movie, I hope the rights hurry up and lapse.
Marvel hasn't announced its plans for 2016. If Universal can't give us a Namor movie by then, I hope Marvel can.
