One of the great things about director Marc Webb is that he gets just as jazzed to talk about premiering an indie film like 500 Days of Summer at the Sundance Film Festival as he does geeking out about just how great and complex the Spider-Man villain Electro is in The Amazing Spider-Man 2. While the two movies are nothing like each other on paper, Webb managed to inject a lot of the playful relationship sensibilities of 500 Days into The Amazing Spider-Man. "There's even more of that in this one," he told us about The Amazing Spider-Man 2, which is set to wow fans at San Diego Comic-Con with a sneak preview during the convention.

Webb was surprisingly relaxed when we sat down with him 24 hours before his big Comic-Con panel to talk all things Spider-Man. On the agenda, of course, was the recent decision to extend this Spider-Man franchise to four movies. "The fourth one was a little bit of a surprise," Webb admitted when we asked if he'd be directing all of them. "We always talked about there being a set of three movies, but there may be elements that expand outside Spider-Man that could fulfill that fourth film," Webb teased, perhaps alluding to some kind of Avengers-like team-up film. Either way it sounds like that fourth movie isn't going to be a regular old Spider-Man movie, but something much bigger and nerdier.

"There's always been a plan to extend this universe," Webb continued. "To make a series of films that were interrelated and weren't purely episodic. That there were certain ongoing stories that were going to play out over more films," he told us. "There have been some early talks about the nature of those next two films, but it's still too early to talk details. If you pay attention to this film that's coming out in May of next year, you may get a feeling and a sense of what's to come in the future."

You can listen to our entire interview below, in which we also talk about the risk of having too many villains in one movie ("we're teasing out some characters that may not be his main foes, but it's really about making life as difficult and complicated as possible for Peter Parker), as well as whether Paul Giamatti's Rhino will eventually get some horns. When we asked, Webb simply replied, "Yes."
