I guess Amy Pascal really did misspeak. Feige and Pascal are back in interview and they clarify what was said in a previous interview; that the Sony Spider-Man spin-offs are a part of the MCU.
While talking to Fandango Managing Editor Erik Davis, Amy Pascal and Kevin Feige clarified that Venom and other spin-offs are not a part of the Marvel Cinematic Universe.
Although it’s been now clarified that Venom and Black Cat are not in the MCU, this doesn’t mean Spider-Man can’t cameo in those films. Yeah I know Spidey is in the MCU, but I think Sony is willing to go pass that and have him in one of the spin-offs.
It’s not really that surprising that the spin-offs aren’t in the MCU, as that would mean for another deal between Sony and Marvel Studios. It’s possible in the future that the two companies could conjure up a deal but I think that would depend on the success of those films.
