According to Screenrant.com, the story broke last August that Mary Jane is not the love interest in director Marc Webb’s new Spidey movie and we all assumed that meant she wouldn’t appear in the film. That was before word got out that two female leads, both MJ and Gwen Stacy, would appear opposite Andrew Garfield in the new Spider-Man. Now The Wrap is claiming that an individual close to the project has confirmed that Mary Jane actually won’t be featured in the reboot at all. How’s that for much ado about nothing?
All of this confusion apparently stemmed from earlier discussions that Webb and screenwriter James Vaderbilt had about possibly incorporating Parker’s red-haired crush into their Spider-Man film. Once Stone officially signed on to play Gwen Stacy, the filmmakers also abandoned the idea of a love triangle (a la Sam Raimi’s Spider-Man 3) and stuck with just one romantic interest for the webslinger.
