A lot of fans are concerned with the amount of villains that will be in The Amazing Spider-Man 2 with Electro, Green Goblin, and The Rhino all being featured in the film. You might be happy to hear that just because there are going to be several villains introduced in this movie, not all of them are going to get a ton of screen time. Director Marc Webb talked about the villains at his South by Southwest keynote saying,
"I'm going to embrace the spectacle. There was a moment deep in the [first film's] post-production process where a giant lizard smashed through a wall chasing a boy-man in a unitard and I said, 'This is not grounded. I'm not going to be beholden to smallness. I want it to be fantastic, to be big, to command and express that feeling when you're a kid and reading the comics. ... I didn't want to hide or shy away from that.
We're obviously familiar with the complaints people had We're very careful to make sure the stories intertwine. For Peter Parker, it's very important that you create obstacles that are difficult to overcome."
He then added that The Rhino is, "in the movie for four minutes." This makes sense as we know that the villain will also carry over into the The Amazing Spider-Man 3. It seems like this movie is just going to set up the character along with Black Cat. I'm looking forward to seeing how far they take these villainous characters in the franchise. I doubt they will kill them all off since they plan on making a bunch of stand alone movies.
