Elisabeth Moss says she had no problem shedding clothes for the nude scenes in her new BBC drama.
The US actress, who shot to fame as Mad Men's ambitious copywriter Peggy Olson, stars in Top Of The Lake, a Saturday night BBC2 series written and directed by Oscar-winning The Piano film-maker Jane Campion.
Elisabeth, 30, said of her character's love affairs in the drama: "There may be a couple of nipple slips. I'm a shy person, but Jane Campion is the last person who is about to make me feel uncomfortable or exploit me. She's the ultimate feminist."
She told the Radio Times: "You go through all this negotiation about what you'll show, and then you get there, three months in and tired, and you're just, 'Whatever, let's just do it'."
Elisabeth stars alongside fellow US actress Holly Hunter in the six-part series about the disappearance of a pregnant 12-year-old girl, set in a remote area of New Zealand.
The actress said of preparing for her role as straight-talking detective Robin Griffin: "I worked out and got some muscle, lowered my voice, learnt an accent and trained with guns. Robin is very much an ass-kicker ... I run all the time and I don't like to run, I shoot guns, throw darts, chop wood and fish."
In 2011, Elisabeth divorced Saturday Night Live star Fred Armisen, who she married in 2009.
"It wasn't working," she said of the marriage. "There was not a lot of wasted time, which was good. I learnt what's important - having a good relationship. I want to have a family and that comes to mind big-time when you're 30, but I'm not in a rush."
She said of having a boyfriend on the other side of the camera - cinematographer Adam Arkapaw: "They're artists, but not actors. It's a better balance. And it worked out for Julia Roberts (who married cinematographer Daniel Moder in 2002)."
She added: "I'm a huge believer in buying your own jewellery because you never have to stop wearing it if things don't work out."
