MoonKnight, Blade, X-Force, X-Men, Fantastic Four, Deadpool, Doom, and fucking Spiderman.
I wish Marvel would have kept more of their licenses.
Is there anyway for them to get them back?
Well, they made a deal for Spider-Man to co-produce with Sony. He'll crossover with Avengers stuff. As Spider-Man is the most popular comic book character in the world, this is probably the best you could ever hope for. Especially now that the future distribution of Bond movies are in contention, Sony will want to hang onto their biggest earner for dear life.
Moon Knight and Blade, to my knowledge, are already home at Marvel. Moon Knight never left and Blade returned after New Line Cinemas opted not to continue with the series. Ghost Rider, Daredevil, and Punisher too, Sony, Fox, and Lionsgate gave those up willingly.
X-Men, Deadpool, and all related characters will probably never leave Fox either. They're consistent earners. It's a lucrative property. Fox has no reason to sell.
The biggest question mark is Fantastic Four and Doom. Fox just made a movie that fucking failed spectacularly, so it's unlikely they'll make a direct sequel. They may try and reboot again in 5 years or whatever, or they may follow Sony's lead and strike a deal to co-produce. My understanding though is that there is some bad blood between Marvel and Fox. The property has potential and Fox won't give it up entirely, is my instinct.
Also, don't forget Namor, who I think is still locked up at Universal. It's complicated, but if I understand correctly, it's a Mexican stand-off where Universal can't make a Namor movie without Marvel's approval and Marvel can't make one without Universal's approval and neither company wants to budge. I could be wrong though. Same thing for Hulk too, essentially. My understanding is that Universal still holds the distribution rights to any solo Hulk movies, which is one of the reasons why there still hasn't been a sequel to The Incredible Hulk (other than the fact that it didn't turn a profit at the box office).
