As you undoubtedly have heard, Marvel/Disney closed a deal with Sony last night and now Spider-Man goes totally bi. He'll be splitting his time between two giant corporate overlords in Sony & Disney. Spider-Man's solo franchise will continue at Sony without Andrew Garfield who will finally be freed to make the movies he was meant to make after breaking through in The Social Network (2010). Cue: roughly 8 million extremely obnoxious internet articles about the casting of the new Spider-Man. I'm steeling myself: It will be so much worse than that hideous landfill phenomenon of infinite speculative Doctor Strange casting thinkpieces.
As for the new Spider-Man -- I swear to god if they start with the origin story again I will never stop puking web fluids. Everyone knows it, dumbasses. It'd be like demanding that each Biblical epic start with a two hour Adam & Eve prologue. Peter Parker will get his next solo film on July 28th, 2017 but first he'll debut over in Marvel's Cinematic Universe. The prevailing rumor is that that's within the context of Captain America: Civil War (due May 6th, 2016) which is also the film that will introduce Chadwick Boseman's Black Panther. That film is getting crowded so one hopes they don't lose the title character in a sea of universe-building agenda.
May 6th, 2016 is a tight turnaround. The ink is still drying on the contract and presumably Sony and Marvel and Disney (that's a lot of executives to please) will all have to agree on a new direction, and a new actor, and that actor's pay scale over multiple films in both supporting and leading roles for seven years (the longest you can book an actor for). And they'll have to do that this summer since Civil War will have to start filming soon to make its release date; visual effects pictures don't come together as quick as Clint Eastwood movies.
For presumably non-competitive corporate appeasement reasons, this Spider-Man deal is pushing most of the post Civil War movies previously slated back about four months.
