The current Spider-Man movie director says that three films will be enough for him. From the Daily Beast:
DB: And you’re signed on to direct the third Amazing Spider-Man as well. Will that be it for you?
MW: I’d like to be involved as a consultant, and I’ve already talked to these guys about it, but in terms of directing it, that will close out my tenure. I’ve had so much fun doing it, but after the third movie, it’ll be the time to find something else.
Amazing Spider-Man 2 hits theaters in less than one month for everyone outside the U.S. and then over two weeks later in America.
