With the recent news of the X-men producer Lauren Shuler Donner answering she would love to have the X-men in an Avengers movie, (find more on that HERE) many (myself included) began to question the possibilities of this.
Some have feel the MCU should just be about the Avengers, but I like many others would like to see it expand from that. With Guardians Of The Galaxy and other probable non Avengers adaptions (Inhumans, Doctor Strange, Iron Fist, Defenders) we already are seeing the MCU grow beyond the Avengers. Marvel's The Avengers alone has not only made more money at the box office than every Spider-man film but nearly gained more box office than all five X-men films. Realizing that Marvel has done all of this with lesser known characters, Sony and Fox are just beginning to see how they could benefit from some kind of deal.
But with messed up continuity, down right awful acting, and some terrible adaptions from the Fox-men ahem, X-men franchise do we really want the X-men in the MCU? In my opinion we do, just not Fox's version.
Say what you want about X-men: First Class but besides some really great acting from Michael Fassbender and James McAvoy the film suffers from some terrible acting and dialogue (not to mention poor character adaptions etc.). Just think of X-men: First Class as a Marvel Studios film... You can't can you? Not only does it have no place in terms of continuity with Avengers (people would be used to people having super powers etc.) but it actually can't hold up to even the worst adaptions in the MCU. It also has done away with any continuity from other films making it more like a One-Shot comic. While it was very nearly ruined with the ending scene of The Incredible Hulk, Marvel understands that continuity is IMPORTANT.
On the other hand Fox thinks that each director should have his own separate vision for each film. For instance like The Wolverine is supposed to be in it's own continuity, which is fine, but they mean it's just a One-Shot. I wouldn't even be surprised if they even mess up the continuity from X-men: First Class to X-men: Days Of Future Past making perhaps both of them One-Shots as well.
This may be the reason Marvel has chosen to go with mostly TV directors (Joss Whedon, Alan Taylor, and Anthony and Joe Russo) with their newest slate of films. As pointed out superbly HERE, TV directors are used to having to deal with continuity from episode to episode, and realize if an one episode isn't received well, it could ruin the whole show.
Doubtless no one wants the MCU to be connected to the Fox's Fantastic Four franchise so lets move on to another current non-Marvel Studio related franchise is Sony's The Amazing Spider-man. While Oscorp was nearly placed in the background of New York City in Mavel's The Avengers, Sony and Marvel seem to have a somewhat strained relationship, yet publicly they put up a good front. While I thought that The Amazing Spider-man was either one of the best or the best Spider-man film to date, I still felt it lacking something. The problem is Sony lets their director take the film in any direction they want but then pulls the strings back hard cutting half their ideas out thus making at best, a very scrambled movie. Marvel on the opposite hand, knows what the franchise needs and thus pitches it to the director, yet lets him to make his own take on their vision. This has worked for the most part with success, although with TV directors doing a number of projects for them, it could work even better from here on.
