We saw the opening 15 minutes and can say that the film opens with an extended, and incredibly thrilling, sequence that fills in some blanks when it comes to Peter's parents. Richard Parker is even more involved in the science behind Spider-Man than previously thought.
Peter and Gwen are graduating high school and heading into the "real' world. Why, Webb explains: "There's a thematic resonance with people moving on, with graduation, which felt really potent to us. The graduation speech was a way to introduce the universe and the themes of the movie in an interesting way. That just felt right."
Spider-Man has always been adored because of his humor. Webb told us that is even more present in The Amazing Spider-Man 2. "We did something that sometimes big comedy movies do, which is you get a roundtable of comedians and you just have them spit jokes out. You can't really tell who's in it! But these amazing comedians, many of them are comic book fans, came in and helped us with coming up with the one-liners and quips that are part of Spider-Man's universe."
Sure, they graduate together. But, in the footage we saw, Gwen and Peter have agreed to separate and it's been a year before they see each other again. See... Peter's promise to Captain Stacy from the first movie is weighing heavily on him.
Dane DeHaan's Harry Osborn has issues, there is no question. Since he will become a Spider-Man villain in Green Goblin, he knows he has an ally in Electro. So, he breaks him out of capture and the two head out to "catch themselves a spider."
