It looks like Emma Stone gets to keep her main man Andrew Garfield a little longer. Director Marc Webb has decided to completely streamline Mary Jane Watson’s story and has cut Shailene Woodley’s appearance from The Amazing Spiderman 2 from the film completely.
“I made a creative decision to streamline the story and focus on Peter and Gwen and their relationship,” said Webb. “Shailene is an incredibly talented actress, and while we only shot a few scenes with Mary Jane, we all love working with her.”
It is likely that Woodley will not return and that the part will be recast.
