She’s taken on her most daring role to date, playing 70s porn star Linda Lovelace in a controversial new biopic.

And now Amanda Seyfried’s first clip for new movie Lovelace has been released online, showing the young actress opening up about her feelings surrounding sex.

Wearing a sexy berry coloured cutout monokini and swapping her long blonde locks for a brunette bouffant, Amanda is seen talking to her second husband Larry Marchiano – played by Wes Bentley – as she takes part in a photoshoot.

She says: ‘At first I’m closed up like a flower bud and then gradually the petals start to open, and then I finally learn about myself and I learn how to enjoy sex. And I feel free.’

Throwing her arms up into the air, the actress giggles away as Larry snaps away on his camera.

Amanda’s character is later seen wearing a floral silk robe and gold hoop earrings as she picks up polaroid photos of herself and promptly gasps.

Larry reassures her: ‘Don’t worry, they’re just polaroid snaps.’

To which she responds: ‘No it’s not that, it’s just… you made me beautiful.’

The Rob Epstein and Jeffrey Friedman screenplay is set to debut at the 29th annual Sundance Film Festival, and shows Amanda, 27, portray the American porn star throughout her rise to fame following her starring role in 1972 movie Deep Throat.

Speaking about her portrayal of the biopic, Amanda revealed to Vanity Fair the hilarious technicalities involved in mastering certain sex scenes with her Lovelace co-star Peter Sarsgaard, who plays her on-screen husband and manager Chuck Traynor.

The Les Miserables star said: ‘We were doing a scene where I was supposed to be going down on Peter Sarsgaard, we used a popsicle, and I had my arms covering the popsicle.

‘It was footage that he was going to show the Deep Throat guy, to get her into the movie, to get her cast. I was laughing hysterically throughout. I couldn’t stop laughing.’

Lovelace also stars Sharon Stone, James Franco as Hugh Hefner, Juno Temple, Robert Patrick, Wes Bentley and Chloë Sevigny.

Last January, Demi Moore was cast as Gloria Steinem in the film but dropped out of production prior to her stint in rehab.

As a result, Moore was replaced by Sex and the City star Sarah Jessica Parker.

Linda Lovelace later became anti-pornography campaigner Linda Marchiano and claimed Traynor had coerced her into the sex movie industry and forced her to perform in Deep Throat at gunpoint.

She further alleged he would beat her during their three-year marriage in the early Seventies and forced her into having sex with other men.
