Thanks to an incredible deal, we know that Tobey Maguire will be up to his old web-spinning ways in Spider-Man 4 (and Spider-Man 5).

Now, Kristen Dunst has confirmed to MTV that she'll be a part of this franchise's fourth installment.

“I’m in,” the actress said simply, not elaborating on any plot details for her character of Mary Jane.

Spider-Man 4 is set to be released in May 2011.
