Now that the title is fixed...
I have not read the comics but aren't they pretty mature? And unless the movie was a toned down version like the previous movie was I think Pixar might want to stay away, they have a reputation for making lovable family friendly movies like Toy Story, Incredibles, Bugs Life, Walli, Monsters Inc, Cars, Up, etc.
Pixar is one of the best storytelling companies in the movies, hard to beat them, but they stick so far to movies that little kids can see and that grown ups would enjoy too.
I could see them doing a movie like the Inhumans, but iwht the violence and action toned down to being at most a PG-13, but would most likely be a PG film (like the Incredibles).
I could also see a Marvel movie, like Howard the Duck, being made by people from Pixar but under a different studio title, not Pixar or Disney but connected in a way.
