"In Spider-Man 3, she begins – oh, the ennui – with an upside-down love scene in a spider’s web. Then she unceremoniously dumps Peter Parker, Spider-Man’s human side.
‘After the success of the first film I got my own hair, make-up and wardrobe people,’ says Dunst. ‘And it’s fun to have your own posse. But I hate the action sequences.
They are slow, painful and very boring to make, as all the action is generated by computers. You sit in a trailer all day doing nothing.
You arrive at 6am, get all dressed up, put on your make-up and it seeps into your pores all day long, which makes me feel like I want to shoot myself.
She dated Dustin Hoffman’s actor son Jake for a while, then actor Ben Foster. After that came her three-year relationship with Jake Gyllenhaal.
‘I’ve only had three relationships in my life and because of them I started to think about everything differently,’ she says. But men get possessive. They love you so much and get angry at your family and then I started to get angry at my family.
I also saw how much someone can judge you and your situation. After my last relationship, I realised just because your family is not like theirs, it doesn’t mean your family isn’t any good.
So I’ve been by myself ever since. No boyfriend. I just haven’t met the person to blow me away yet. I have high standards.
Listening to Dunst, what’s interesting is that she seems to have come through it all relatively unscathed. She’s composed and articulate. She is philosophical now about her childhood and has managed to avoid the pitfalls child stars typically fall into.
‘I drink moderately,’ she says. ‘I’ve tried drugs. I do like weed. I have a different outlook on marijuana than America does.
My best friend Sasha’s dad was Carl Sagan, the astronomer. He was the biggest pot smoker in the world and he was a genius.
‘I’ve never been a major smoker, but I think America’s view on weed is ridiculous. I mean – are you kidding me? If everyone smoked weed, the world would be a better place.’
She also reveals that, contrary to reports, there is likely to be at least one more Spider-Man film. And despite all that hanging-around-the-trailer boredom, she’s up for it.
‘Yes, I’d definitely do Spider-Man 4. As long as Sam Raimi is the director and Tobey is the star and there is a good story to tell – I’ll be there with bells on.’
