Some may not know, but there were rumors all over the place in the past couple days that Drew Goddard was most likely going to write and direct the new Spider-Man movie, and that Dylan O'Brien could have already been cast as Spider-Man. Now in an article I read (http://whateveraspidercan.com/2015/03/03/drew-goddard-denies-marvels-spider-man-film-involvement/) it said that Drew Goddard has not even spoken with Marvel about doing anything with the new Spider-Man movie, and that Dylan O'Brien was not cast as Spider-Man and that casting for the film hasn't even started yet. They say that Dylan O'Brien is too old for the role at the age of 23 because that want a young actor to grow up in the role (like the Harry Potter movies).
All I know is that I want to know TRUTH! I think having someone grow up in the role is a good idea but I only want Dylan O'Brien to play the role. Drew Goddard I think would be a great person to write/direct the film but no one knows who's even talking with Sony and Marvel at this point. If I were you I would not trust a single rumor you hear about anything related to this movie because it most likely won't be true unless Sony or Marvel officially announced it.
