Actress Margot Robbie had mixed feelings when she learned she had won the role of LEONARDO DiCaprio's movie wife in The Wolf Of Wall Street - because she'd have to strip for the cameras.

The modest Australian admits she auditioned for the role of Naomi Lapaglia on a whim and never thought she'd have to worry about the film's nudity - because she felt sure she wouldn't get the part.

She tells Wenn, "I did the audition tape in L.A. and never expected (director) Marty (Scorsese) to see it. We were just hoping that (casting director) Ellen Lewis would see it. She handed it straight on to Marty and then I got a call saying Marty wants to see me read with Leo in a room with him in New York.

"There was the nudity thing with Wolf Of Wall Street and I didn't want to do nudity but then why did I audition?

"In hindsight the nudity seemed really intimidating but now that I've done it, it doesn't seem like a big deal at all. There was no question of why it was in there. There are scripts I pick up where there is no reason why I'm getting my clothes off (sic). That's nudity for the sake of nudity which I do not agree with, ever. But when the nudity is warranted I totally agree with it.

"In this case that's Naomi's power over Jordan and her currency in the world of millionaires. It makes perfect sense for her to use her body to manipulate him."

But she still had to confront her ethics: "For the sake of showing it on screen I had to confront that somewhat shock value... It was, 'Am I able to deal with that?' It's just different in this day and age because of the internet that if I do this it will be forever on YouTube.

"And it's not just a repercussion on myself (sic) but my family, my brothers and my grandparents have to deal with that! It affects everyone around me, so it's not something to be taken lightly... But, if there's ever a time to do nudity, it's in the hands of Martin Scorcese. He will do it tastefully and he doesn't exploit nudity, so I was confident in the fact that it would be done well and would be done tastefully. It was too good of an opportunity to pass up."
