Whether you like it or not Spiderman is Sonys top franchise and it does make them money. Sony will not just hand it over because Marvel fans say so and this line of thinking is silly. Can we at least come up with realistic scenarios, I know some of you have some business savy, what would Marvel need to do to get Spidey either completely of on a shared basis and what offer would Sony most likely accept...thoughts?
I think a deal that is similar to what happened with the Incredible Hulk between Marvel Studios and Universal Studios and what happened with the Indiana Jones IP between Lucasfilm, Walt Disney Pictures, and Paramount Pictures, but more beneficial to Sony Pictures.
While Universal Studios was a simple distributor for the Incredible Hulk and collected a distribution fee of 15% or less while Marvel Studios fronted the production budget, Sony Pictures would be a full production partner assuming 40% - 50% of the project and keep distribution rights in key territories such as North America and other English speaking territories, Japan, South Korea, etc. through their Columbia Pictures banner. Sony Pictures Home Entertainment would also keep home video and VOD distribution rights in key territories. And just like with Indiana Jones, Sony Pictures keeps full rights to previous films
Marvel Studios would assume full creative control of the Spider-Man character in perpetuity and assume 50% - 60% as a production partner. The biggest reason why Marvel Studios' films have been successful, especially in the Phase 2 set of films is because Marvel Entertainment has had full control of the characters it is making films on, not some other studio like 20th Century Fox, Sony Pictures, or Walt Disney Pictures. And in order for Spider-Man to fully sync with the Marvel Cinematic Universe, Marvel Studios would need full creative control. This means no more studio heads like Amy Pascal or corporate heads like Kaz Hirai interfering with the Spider-Man character the way they have in the past.
The Walt Disney Motion Pictures Group would assume marketing rights to future Spider-Man films and assume distribution rights in lesser international territories. The marketing division in Sony Pictures is pretty much a joke while the Walt Disney Motion Pictures Group has really marketed the hell not only with Marvel films such as the Avengers, Captain America: The Winter Soldier, Iron Man 3, and Guardians of the Galaxy, but other properties too like Frozen, Alice in Wonderland, Maleficent, Toy Story, etc. They are a marketing juggernaut and would do a far better job at making the film successful than Sony Pictures would. Walt Disney Studios Home Entertainment would be able to bundle future Spider-Man films.
Disney Consumer Products keeps the merchandising and licensing rights to the Spider-Man IP as Sony Pictures has previously relinquished those rights. Disney-ABC Domestic Television and ABC Studios keep the television rights as Sony Pictures has also relinquished those previously.
