Kirsten Dunst says she will have to be paid an "exorbitant" amount of money to appear in future Spider-Man films.

The actress, who plays Mary Jane Watson, will appear in the third film but is uncertain if she will appear in any more.

According to Teen Hollywood she said: "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 (director) Sam Raimi is on board, and everyone is, then maybe. But this is what I am signed to do - three."
