Amanda Seyfried has followed the innocence of Mamma Mia! with two sexy roles. Steve Pratt reports.

KISSING girls is getting to be a habit for Mamma Mia star Amanda Seyfried. After singing and dancing as the bride-to-be in the Abba musical, she’s starred in two movies calling for her to indulge in same sex snogging.

First she kissed Transformers pin-up Megan Fox in the horror comedy Jennifer’s Body and now, in the erotic drama Chloe, she shares an intimate love scene with Julianne Moore.

So how was it for her? “It was unnatural – I say that with a grin,” says Seyfried.

“Seriously, it’s not the type of scene any actor is ever comfortable doing. Any kind of intimacy is strange. It’s not your partner – it’s the actor or actress.

“ I don’t know what goes through my mind when I do these scenes. I’m listening to the director’s technical directions, because things need to be in sync with the camera’s movement. It was all one shot, too, so you couldn’t piece together the scene at all, which I think is beautiful. I love it when directors do that, with one long shot. It was very difficult.

“We laughed a lot. The best way to get through it is joking about it. Julianne was a good co-star. We’d go through things together. It’s a journey.”

In Chloe – a remake of the French film Nathalie – she plays the title character, a naive young prostitute hired by Moore’s character to see if her husband will be unfaithful, but who ends up falling in love with the wife.

She admits that the nudity in the movie was risky, adding that she “definitely negotiated my way out of some stuff”. She was happy to do whatever director Atom Egoyan required in terms of nudity.

“But I knew he wouldn’t need much because he doesn’t really like to use it that much. He’s a little uncomfortable with nudity.

Even though he has made all these erotic dramas he’s uncomfortable with it.

“I know a lot of people would disagree with me on that but nudity, I am sorry, is not a big deal.

“It’s a beautiful thing when it is used in the right way. And Julianne has proved that. She’s stunning.”

The worldwide success of Mamma Mia means that everything’s changed for Seyfried. “Basically, I started to get all these opportunities. I became known in the world. I can go to any country and certain people will know who I am, because Mamma Mia! was so widely received.

It’s amazing. A movie like that changes so much, I mean I’m on the cover of magazines in the UK. That’s weird. I mean it is great too.

Chloe came before Mamma Mia ever came out – but yes, now people hire me.”

If she appears grounded, she attributes that to her mum. Whenever Seyfriend is at home, she makes her sit down and answer her fan mail and things like that.

“Or else I’d never do it.

But when I’m done and I see that I have written letters back to people, I feel good.

“Sometimes they give me questionnaires. Everyone wants them. They’re so greedy. But I find things out about myself. Everybody asks me about my favourite food and I keep saying cheese. They ask me these silly questions. I recently got asked my favourite recipe.”

And her favourite recipe at present, in case you were wondering, would be for pumpkin bars “because everybody loves them”. She also made a chocolate Mexican cake for a friend’s birthday that a food critic tasted and declared was really good.

“Food is a bit of a vice actually. I would like not to eat so much. Really, I tend to overdo it on the sugar, which isn’t good for you.

“I’d like to cut dairy out a bit. I don’t smoke, and I don’t drink too much. I do curse a bit but food is an indulgence.”

Acting-wise, she’s been receiving a good variety of scripts in the wake of Mamma Mia. The only time she was typecast followed her screen debut in Mean Girls, after which she received a lot of scripts for dumb blondes at high school.

“I didn’t take any of them,” she says. “Also most of them were badly written.

And I knew we were going towards something else. “ After Chloe, she’ll be seen in the love story Dear John opposite Channing Tatum, directed by Lasse Hallstrom and based on a book by Nicholas Sparks.
