Dunst Back for Spidey 4 September 30, 2008 Kirsten Dunst back for Spider-Man 4 (and 5?) After some speculation whether or not Mary Jane would be in Spider-Man 4 and 5, MJ actress Kirsten Dunst accidentally revealed that she will indeed be returning to the series. “I’m in,” said the actress matter of factly, however, when pressed to make the announcement official, Dunst quickly changed her tone, and rather cryptically added, “I’m not saying anything, I know there’s rumours…” Dunst has a history of spilling Spidey spoilers. It was she who confirmed rumours that Sandman and Venom were the villains of Spider-Man 3. Sony is targeting a May 2011 release for the fourth pic.
