Due to a contractual commitment to Fox, Marc Webb might not be able to direct the May 2nd 2014 slated Amazing Spider-Man 2. Reportedly, he is contacted to make one for film for FOX before he’s let out of his contract. Also because certain Spider-Man scenes took lengthy amounts of time to direct, cut and edit Columbia is beginning to worry. They haven’t began a search for new directors yet, but it’s safe to say this is a legitimate concern.
