There's been rumors stating that Marvel and Fox are planning an Avengers X-Men movie crossover, with one even stating it's supposed to happen in 2020.
To add fuel to the fire, Kevin Feige booted Marvel CEO Ike Perlmutter from being involved with the movies. Perlmutter was a potential roadblock to working with Fox as reportedly Perlmutter is feuding with Fox over the Marvel character film rights.
In addition, Marvel is working with Sony on Spider-Man: Homecoming, and Spidey recently debuted in the MCU during Civil War, leading to speculation an Avengers X-Men movie could happen.
While we can all dream if an Avengers X-Men crossover movie will ever take place, it may not be in the cards, at least according to Captain America: Civil War and Avengers: Infinity War director Joe Russo.
“As far as we know, right now there isn’t talk regarding the X-Men," Russo said while promoting the Captain America: Civil War Blu-Ray, reports Screen Rant. "I don’t know if behind-the-scenes there were conversations or if there are conversations happening but we certainly haven’t heard of any… Sony and Marvel had a relationship through Kevin [Feige] and Amy [Pascal], and through us and Amy. That’s really how Spider-Man came about. It requires a certain alchemy and a very special situation for studios to share properties. There was not talk on Civil War about the X-Men.”
While Joe Russo offers potential bad news about an Avengers X-Men crossover, the good news is that Marvel Studios president Kevin Feige actually has a good relationship with Fox and X-Men producer Lauren Shuler Donner.
"I would love it. I would love it," Donner said a couple of years ago in an interview. "I personally have close ties to Marvel because of Kevin Feige, because Kevin worked for me. But to take our characters and mingle them in the way that they were written, yeah, absolutely."
Likewise, back in April while promoting Deadpool, Tim Miller and Simon Kinberg offered they would love an Avengers X-Men crossover.
"I would love to some day in part heal the rift between the world of X-Men and the world of Avengers," Tim Miller said.
"Yeah, I think we all would," Simon Kinberg added. "There's so much crossover in the comics it would be neat to one day be able see those characters share a movie."
"Kevin [Feige] is so awesome," Miller continued. "Did you see my little pizza box in one of the scenes? 'Feige's Famous Pizza' -- that was my little.. trying to bring these worlds together."
"Both of us are actually quite close with Kevin and have a profound amount of respect for what he does," Kinberg offered. "And it would be fun to all team up one day, somehow, together, if that could work."
"I think it's a super smart move with Spider-Man. I mean, he's great," Miller said.
Deadpool also featured a Marvel Studios Hellicarrier at the end of the film (at least in concept art), so maybe we shouldn't rule out an Avengers X-Men crossover just yet?
