The writers of Captain America: Civil War were recently interviewed by The Hollywood Reporter. Among other things, Steve McFeely and Chris Markus talked about what it is like to be key players in the ever-changing Marvel Cinematic Universe. One of the topics that came up in the interview was what they would do with complete creative freedom at Marvel Studios. They were asked: if you could bring in anyone or anything to the MCU, what would it be?
Steve McFeely's response was that he would introduce the king of Atlantis: "Namor. He is kind of a jerk and has a chip on his shoulder and he is a king and lives underwater. The degree of difficulty is so high, though. Cause it could be a great movie or it could be truly terrible." Personally, I think bringing Namor into the Marvel Cinematic Universe would add a really interesting new element. There is something very dramatic about Namor both in character and visually. However, Marvel may decide not to do this, at least for a while as DC are already doing Aquaman. They have been beaten to the Atlantis punch so they might just leave it be and go for a different look.
Chris Markus' response had much bigger implications than the appearance of one character. He had this to say: "I think it would be cool to make a Marvel Zombies movie but that would require a whole other wing, or at least, another dimension." Although I cannot see Marvel confusing casual fans with a separate movie universe, a Marvel Zombies movie would be awesome. Having read some of that series myself I know that it would make for a visceral and exciting experience. Also, given that there is now a precedent and a desire for hard-hitting R-rated superhero movies, it would definitely be something that fans want to see.
