The reaction to Andrew Garfield as Spider Man was mixed, but Sony believed him enough that they have booked three sequels. Sony has a long term plan and Harry Osborn and Oscorp are right in the middle of it.

A month ago, Garfield mentioned that he is not signed for The Amazing Spider Man 4 so there were rumblings that "The Amazing Spider Man 4" will actually be filled out by one of the spin off movies, possibly "Sinister Six." IGN had a chat with writer Roberto Orci on this matter:

"IGN: There are release dates through Spider-Man 4. Will that be a continuation of the Spider-Man franchise or might what we're calling The Amazing Spider-Man 4 be a placeholder for Sinister Six or Venom?

Orci: There were three superheroes I loved when I was a kid: Superman, Wonder Woman and Spider-Man. I think it's such a popular character, and when I see my friend's kids, I remember why somehow, it sinks into kid's brains. So no, I think with Spider-Man 4, the intention is for it to be "Spider-Man."

The interview continues with the revelation of the expanded role of Harry Osborn (Dane De Haan) who will probably stay beyond TASM 2, and the role of Oscorp as the central figure.

"IGN:  When we're looking at the trailers for something like Spider-Man 2, there's certainly a lot of villains. It looks like Oscorp may be the central fulcrum that all of these villains are spinning out from. Is that a technique you guys are using to unify this world and make it more cohesive?

IGN: Then Norman and Harry can carry through as a central players...

Orci: That family, yes.

IGN: It seems like a particular challenge though to introduce all of these new characters and maintain the focus on your central characters. How do you do it?

Orci: The way we do it is to make sure that their presence is based on a character thing that necessary for the theme of the movie. You can't just throw somebody in there to show up and make it harder on Spider-Man. The stories that we have for these guys, they're tragic villains, you're going to find out, a little bit. It's not as simple as "Evil dude shows up." Jamie Foxx has some very touching scenes. As long as I can describe their stories and character terms, then I feel like it's okay. If you can't, then you know you're having them crash-land out of nowhere, and what's that about?

 'The Amazing Spider Man 2' will have Electro and Rhino as central villains, although The Daily Bugle Tumblr has introduced more familiar names in their human roles. The goal is to show them as people first. Not villains on the onset.

From Sony/Columbia Pictures, the official release dates: "The Amazing Spider-Man 2 opens in U.S. theaters on May 2nd, 2014, followed by The Amazing Spider-Man 3 on June 10th, 2016 and The Amazing Spider-Man 4 on May 4th, 2018."
