Marvel got the Fantastic Four back? That's great news, those movies were pretty crappy. Maybe now they can do a proper Dr Doom and/or Galactus.
EDIT: Oh, that's a list of superhero movies, not Marvel movies. So Fox is rebooting it? Still could be an improvement.
Marvel paid for some of their galactic villains and cosmic characters back but Fox is keeping FF4.
The Marvel cinematic universe contains most of the Marvel Characters. All of the Avengers + others: (Hulk, Iron-Man, Captain America, Thor, Ant-Man, SHIELD, Guardians of the Galaxy + the 4 characters we'll be seeing on Netflix... Daredevil, iron-fist, etc) ... All those characters belong to the same universe and theoretically can cross paths at any time.
Sony owns Spider-Man's film rights. So all the Spider-Man characters/villains you saw in the 3 Toby MaGuire movies + the rebooted 2 Andrew Garfield movies... those all belong exclusively to Sony and can't cross over and thus exist in a separate movie universe. They intend to spin it off into multiple franchises that tie into the same Universe... like a Venom movie, for example.
Fox owns the rights to all the X-Men characters. Basically all the Hugh Jackman X-Men movies are supposed to exist in the same Universe since 2000 when the first one came out. The films suck at continuity, though... so there's tons of issues... especially the standalone Wolverine films. Very messy. Then they launched X-Men First class intending it to be separate, but realized they could make a lot of money going the "Marvel Cinematic Universe" route, so they intend to tie it all together (with the older X-Men movies) with this new one (Days of Future Past) that is coming out... I assume they'll use time travel to fix some of the broken continuity.
Additionally, FOX owns the film rights to Fantastic Four... so they intend to reboot it (with MIchael B. JOrdan as Human Torch, for example) and it's intended to exist in the same universe as their X-Men characters. Basically, Marvel Studios changed the game by having this epic movie universe all tie together. So now all these other studios who own the movie rights to these other characters are trying to do the same thing... so expect this new Fantastic Four to have some crossover with the X-Men movies.
So unfortunately none of the Marvel Studios characters can show up in Sony (Spider-Man) or Fox (X-Men/Fantastic Four) movies and vice versa. You'd think the studios would make some agreement where they could all benefit, but the issue is that if Spider-Man showed up in an Avengers film, the studios can't decide how much money Sony should get by having Spider-Man in the movie.
Other studios are trying to do their own thing, but unfortunately Marvel has a head start on them and are doing this perfectly (starting with the first Robert Downey Jr Iron-Man movie). It's all extremely well thought out. They work very hard to make sure everything ties together and fits. An example is the Ant-Man movie they are making (starring Paul Rudd). Edgar Wright (Hot Fuzz, Shaun of the Dead, Scott Pilgrim, etc) has been attached to direct that little comedy/superhero film since 2006. Marvel Studios put it on the backburner while they launched this huge cinematic universe. Now that they are set to finally make the movie, they had to go back to the script (from 2006) and re-write certain aspects so that it fit with the rest of the Marvel cinematic universe. They are doing this the right way.
On the flip side you have Warner Brothers... who owns the rights to ALL the D.C. Comics characters... and it's a complete mess over there. They don't have this thought out at all. Nolan's "Dark Knight" movies were in a standalone universe. The TV Show "Arrow" is in a separate universe that includes a new spin-off Tv Show based on Flash. The upcoming TV Show "Gotham City" has nothing to do with Dark KNight or any other Batman property. Smallville has nothing to do with any of the Superman movies. They made "Man of Steel" intending it to be a completely standalone universe. As they were making "Man of Steel", Warner Brothers saw how successful Avengers was and decided they needed to make a Justice League movie ASAP... so they started casting for a Justice League cash grab that would have starred completely different actors as Batman and Superman. Yeah, the idiots intended for there to be two Supermans (one from Man of Steel and one from Justice League) at the same time. Luckily they realized that was a idiotic idea... so they decided they'd just shoehorn Batman into the sequel to "Man of Steel" (even though they never intended for them to exist in the same universe)... So they threw 50 million dollars at Christian Bale begging him to show up in the movie. But luckily, Bale has artistic integrity and turned down the movie... feeling that NOlan's "Dark Knight" trilogy fully told the story and it would be spitting on that vision by having the character show up in a sci-fi film with space aliens. Then they decided they'd just cast Ben Affleck as a "weathered and experienced" Batman. I'm fine with that... but it's a little weird for Batman to show up in the next "Man of Steel" movie without any origin. Was he just chillin out in Gotham during the events of the last "Man of Steel" movie? Weird. But Warner Brothers is impatient... so apparently Wonder Woman is going to show up in that movie too. Probably other characters to. They want to fast-track this thing to a Justice League movie. Oh, and the Ryan Reynolds "Green Lantern" will have nothing to do with it either. And that "Gotham" TV show will have nothing to do with the Ben Affleck Batman. And they'll likely have a Flash in it that will have nothing to do with the TV Flash. Warner Brothers is a mess. But ultimately their goal is to have a movie universe where Batman, Superman, Flash, Wonder Woman, Green Lantern, etc all cross over. I think they are blowing an opportunity with their TV shows, though. If it was up to me, the "Gotham" TV show would be the origin story for Affleck's Batman. Why not? They got some idiots running that studio.
