Today, I will present you with the current chart regarding the Marvel Movie Rights and will explain to you which company owns or owned which character(s), team(s), or properties as of 2018.
With the purchase of 20th Century Fox by Disney (which will be official by mid-2019), Marvel Studios has now regained the film and TV rights to the X-Men and the Fantastic Four, as well as their side characters like Doctor Doom, Silver Surfer, Galactus, Annihilus, Kang, full rights to the Skrulls (including Super Skrull), Mole Man, Deadpool, Cable, Apocalypse, full rights to Quicksilver and Scarlet Witch, full rights to the Watchers (including Uatu the Watcher), the X-Force, Alpha Flight, New Mutants, Future Foundation, etc.
Universal Pictures still maintains the distribution rights to the Hulk and his characters (Red Hulk, She-Hulk, A-Bomb, Skaar, Red She-Hulk, Doc Samson, Abomination, Leader, Ravage, etc.) , while Marvel Studios owns the production rights, meaning that they can make as many Hulk films as they want as long as Universal distributes. But, due to Universal making a right to first refusal deal, if they say no and don't want to distribute The Incredible Hulk 2, those rights go back to Disney. So, either way, Marvel Studios has the film rights to the Hulk and his characters and can make as many Hulk movies as they want, with or without Universal. Namor is also owned by Marvel Studios, but still has some contracts with Universal that Marvel needs to take care of before he can appear in the Marvel Cinematic Universe.
The only movie rights that Marvel Studios and Disney doesn't own is Spider-Man and his characters (Mary Jane Watson, Gwen Stacy, Norman Osborn, Liz Allan, Flash Thompson, Ned Leeds, Aunt May Parker, Uncle Ben Parker, J. Jonah Jameson, Robbie Robertson, Betty Brant, Miles Morales, Cindy Moon, Spider-Woman, Scarlet Spider, Spider-Man 2099, Spider-Man Noir, Black Cat, Silver Sable, Venom, Carnage, Sinister Six, Green Goblin, Doctor Octopus, Sandman, Electro, Vulture, Tinkerer, Chameleon, Kraven the Hunter, Shocker, Hydro-Man, Rhino, Lizard, Scorpion, Mister Negative, Hobgoblin, Spider-Slayer, Mysterio, etc.), which are currently still owned by Sony Pictures/Columbia Pictures. Disney and Sony made a deal to integrate Spider-Man into the Marvel Cinematic Universe on February 2015, starting with Captain America: Civil War. Marvel Studios will maintain creative control over Spider-Man in the MCU, while Sony co-produces via Columbia Pictures and distributes the solo Spider-Man films. Sony plans on starting a Sony Marvel Universe that is separate from the Marvel Cinematic Universe under Disney, and they will be focusing on characters they own other than Spider-Man. Confirmed films for the Sony Marvel Universe so far are Venom, Silver and Black, Silk, Sinister Six, and a Kraven/Mysterio spinoff film.
And that is the current status of the Marvel Movie Rights. I hope I was able to help explain things properly for you guys.
