Even though The Amazing Spider-Man 2 doesn't hit theaters for another year, fans are already talking about Sony's announcement in June that confirmed The Amazing Spider-Man 3 will be released in 2016 and The Amazing Spider-Man 4 will debut in 2018.

Director Marc Webb revealed last week that the announcement did come as a surprise, but in another interview, he spoke about how the fourth movie could include new heroes fighting alongside Peter Parker.

"Well, I think this was conceived of as a trilogy so there was a defined architecture to the story we were telling and we had sort of a rough outline of what was going to happen. I think [for] the fourth movie, what we've discovered is there are so many ancillary characters, that have enormous, cinematic potential that there may be other ways to exploit those characters, in a way that is exciting and fun and worthwhile. It might not just be a Spider-Man movie."

Perhaps the director is taking a cue from Warner Bros.' massive announcement that Man of Steel 2 will include both Superman and Batman. The filmmaker also teased the possible inclusion of the super villain group The Sinister Six, and if that story line does happen in The Amazing Spider-Man 3 or The Amazing Spider-Man 4, Andrew Garfield's Spider-Man will likely need all the help he can get.
