Why do we have to rewrite fake history? There's totally room for more scientists in the Marvel Cinematic Universe, especially since Reed Richards and the Fantastic Four belong to Fox. Richards is the ultimate Marvel scientist, not Bruce Banner and Tony Stark. An argument could be made that the MCU is actually devoid of scientists. Banner's post Hulk research has been more or less self-centered in its focus (ie. How do I get this green beast out of me!?!?) Stark is an inventor akin to Elon Musk. Sure, there's science in what he does, but he's NOT A FREAKIN' SCIENTIST! There is plenty of room for Hank Pym.
I really hope that Ant-Man isn't a one-and-done film. Hank Pym and Scott Lang are among the most emotionally and intellectually complex characters ever to be inked by Marvel! Imagine Michael Douglas & Robert Downey Jr. riffing tech on screen! That would be fantastic! (I've never seen Wonderboys, which they were both in, did they share screentime?)
I'm only really "comically passionate" about Daredevil & AntMan in Marvel Comics, and Invincible in Image Comics. I rarely read anything else. The new Daredevil series starts on Netflix in April, and Invincible needs to happen somewhere sometime. Apparently Robert Kirkman has another comic that he made into a popular series. ;)
