Kirsten Dunst has warned Hollywood bosses they will have to pay her an "exorbitant" amount of money to star in another Spiderman movie, because her initial contract was for just three films.

The beauty, who plays Spiderman's love interest MARY JANE WATSON, is adamant she will not return to the role after filming on SPIDERMAN III is completed - unless swayed by a huge salary and an amazing script.

She says, "Unless they pay me an exorbitant amount of money, this will be my last one.

"If there is more of a story to tell and Sam Raimi (director) is on board, and everyone is, then maybe.

"But this is what I am signed to do - three."
