The Los Angeles Times has a very interesting piece up about the deal between Marvel Studios and Sony Pictures which brought Spider-Man into the Marvel Cinematic Universe and it starts with a look back at what exactly the latter group had planned following the release of The Amazing Spider-Man 2. Apparently, they realised that something had to change following the release of that disappointing sequel and their ideas included a new standalone series and a reintroduction for the wall-crawler through the scrapped Sinister Six movie. Both ideas were deemed to be too "convoluted," however.
Marvel Studios President Kevin Feige actually approached Amy Pascal back in 2014 with the idea that Spider-Man should be brought into the MCU but it was a meeting in early 2015 between Sony's then top two executives Michael Lynton and Amy Pascal at the home of Marvel Entertainment Chief Executive Isaac Perlmutter that sealed the deal and saw Feige handed the reigns to the franchise.
Sony paid for Spider-Man: Homecoming and will keep all profits from it, but money did change hands when they paid Marvel an undisclosed producers fee for their help. However, they're expected to benefit from a huge surge in merchandising as Marvel actually owns the rights to that side of things.
While Feige was given creative control, Sony's Amy Pascal remained instrumental in many key decisions including the casting of Tom Holland, the development of the script and the hiring of Cop Car director Jon Watts. She also played a huge part in the development of Michael Keaton's Vulture and while the reboot was shot in Atlanta, it was edited and scored on the Sony lot in Culver City. What do you think?
