Amanda Seyfried was demure in a red dress at the 63rd Berlinale International Film Festival in Berlin, Germany, where her film “Lovelace” is screening. Peter Sarsgaard and James Franco were also on hand.

The movie may be her most risque yet. She plays ’70s-era porn star Linda Lovelace, who starred in “Deep Throat,” the most successful adult film in the industry’s history.

The film was the first to have a plot and made Lovelace and overnight success. But behind the facade, she was abused and badgered into doing the film, which focused on her talent for performing fellatio.

Seyfried, 27, said she took the movie’s nude scenes in stride. “I don’t know why I’m comfortable; nudity, whatever!” she told the assembled reporters.

“Sex:… we all do it! There’s a time and a place to be naked,” she mused.

The actress also had some nude scenes in the 2009 erotic thriller “Chloe,” with Liam Neeson and Julianne Moore. She and Moore even had a hot girl-on-girl scene.

As for the film itself, Seyfried said: “It was very intimate; it was very dark. It was surreal, at times. I got to experience amazing things in a small amount of time with amazing people.”

Seyfreid’s most recent film “Les Miserables,” is up for several Oscars and has received nine BAFTA nominations, the British equivalent of the Oscars.
