Reese Witherspoon graced the cover of Vogue's October 2014 issue and she has a lot of things to reveal about her sex life - on the film, "Wild."

Witherspoon has not been lucky with her past movie deals and now, she's more than willing to take some risks to boost her career, according to US Weekly.

"When people underestimate me, it's actually a comfortable place for me. Oh, that's what you think I am; well, no, I'm not.' I'm a complex human being. I have many different shades," she told the publication.

Talking about her sex scenes in the film, Witherspoon dished that she wanted all of it to be organic and realistic as possible.

"I just didn't want to hear, 'Oh, we don't want to see Reese have sex... Oh, can we not have any profanity?' I wanted it to be truthful, I wanted it to be raw, I wanted it to be real," she dished.

The "Mud" actress also revealed how similar her role in "Wild" is to that of her real life.

"Nobody knows what goes on behind closed doors, but I think there's a general sense now that I've lived a pretty textured life. So many of the things that Cheryl goes through in the book I've been through, you know? I've been married, I've been divorced. Cheryl has this idea that the things that have happened to you are part of you. There's something really beautiful about that idea," she explained.

Meanwhile, Witherspoon was spotted at the "Gone Girl" premiere in New York on Friday. The producer of the film was seen in a form-fitting red gown that showed off her stunning curves, the Huffington Post reported.

In a previous interview with Vanity Fair, Witherspoon dished on why she opted to work behind the scenes for the film.

"A couple of years ago I started looking at the scripts that were coming in, just through the normal Hollywood pipeline, and I was sort of dissatisfied with the parts for women. And I thought, if I don't get busy trying to produce things - for myself, for other women, who's gonna do it?" she said.
