Why is Prof. X farting across Washington DC?
Marvel would probably throw out the prejudice and racism themes and have the X-Men beating up Evil Guy of the Week who wants to destroy the world because of reasons. Throw an Avengers teaser at the end and we're done.
It's Fox and it's never happening. Fox has shown that they can spit out XMen/Wolverine movies like nobodies business which keeps the agreement alive. To be honest, I'm surprised so many people want this. I mean, Fox has delivered 2, maybe 3 or 4 good Xmen movies and 2 stinkers which seems to be a pretty good average. It's not like Marvel is immune to putting out bad movies and if they had Spiderman and Xmen, you likely wouldn't see them putting resources into stuff like Guardians of the Galaxy.
