This will be the first Spider-Man movie where a villain returns from a previous movie. Paul Giamatti confirmed that the Rhino will return in the third film, but it is unknown if he will have a major role.
The film was originally scheduled to be released on June 10, 2016, but Sony announced in summer 2014 that they had pushed the movie back to 2018 in order to release the Sinister Six movie, which is scheduled to premiere on November 11, 2016.
On Peter Parker passing the torch to Miles Morales in this film, Andrew Garfield stated: "Miles Morales was a huge moment in this character's comic book life. And I do believe that we can do that. It's something I'm really interested in figuring out; an eloquent way of coexisting, or passing on the torch. I don't have an answer, but I think it's actually a really important move. I think it's a really beautiful and important move. I want it to feel like a circle. I want the two ends to join, somehow. I don't know what that means, yet. I don't know what that means in terms of the quantity of Spider-Man movies I do. But I know that I don't particularly want to be a 40-year-old Spider-Man. [Laughs] I do know that time is fleeting."
According to an interview with Indiewire on May 2, 2014, The Amazing Spider-Man 2 producers Avi Arad and Matt Tolmach say that as long as they are in control, Peter Parker will remain as the cinematic Spider-Man. Although, since Andrew Garfield's contract expires after this film, and he has heavily implied multiple times that he won't extend it, the producers might not have much of a choice in the matter.
