Amanda Seyfried has revealed that singing was more "terrifying" than stripping.
The Mamma Mia! actress, who had to bare her body to play Deep Throat star Linda Lovelace in biopic Lovelace, admitted performing with a live orchestra for Tom Hooper's Les Miserables was a scarier prospect.
"Nudity is just a costume - I would only do it if it was necessary. I think watching sex scenes in movies when people have their comforters pulled up to their chests is just ridiculous, and I'm all about realism in films to a point," she said.
"But singing live every day was just terrifying. Every day, just putting that earpiece in and having everybody listen to you a cappella because you're the only one that can hear the accompaniment, was terrifying. It was awful. I loved it but it was really hard," she admitted.
Amanda decided to watch the original Deep Throat to prepare herself for her Lovelace role.
"I didn't have to watch it, but it would have been nuts not to see it. I wanted to understand the tone of it, but it was really boring. Kinda kitschy, really terrible acting. They tried to do something different and they succeeded," she said.
The 27-year-old actress revealed that Linda's children, Dominic and Lindsay, have been on board throughout the making of Lovelace.
"Rob and Jeffrey Friedman, the directors, were very much in touch with her lawyer and her two kids and they were very supportive. They are still very supportive and they are proud of it because it portrays their mother in the way she would have wanted to be portrayed. It's the best we can do," she explained.
