Reese Witherspoon Plays Drug Addict in New Film 'Wild,' Admits Being 'Really Confused' For Role

Reese Witherspoon covers Harper's Bazaar UK's January 2015 issue and chats about her new role in Wild as a drug addict, however she had a hard time relating to the role.

"I've never done drugs," she shared with Harper's Bazaar U.K. "I was really confused. I didn't know what I was doing."

The film is a based on the memoir Wild: From Lost to Found on the Pacific Crest Trail written by Cheryl Strayed. In the memoir Strayed decides to hike more than a thousand miles of the Pacific Crest Trail alone, on a way to find herself following her mothers passing, a divorce and years of destructive behavior.

"It just required being in a really raw emotional place that didn't feel good," she continued to tell Bazaar. She also get's in detail about the sex scenes that she had to do in the movie. "[The sex scenes were], like, three percent of the movie, but it took up a tremendous amount of fear in my mind because it's daunting. Sometimes I was just terrified. Like a cat on a raft ... 'You can't make me do it.'"

Witherspoon has admitted that this is one of the hardest movies that she has ever had to make — referring to the emotional drama that the plot ensues.

"[Dramas are] always going to require something that doesn't feel good, some sort of challenge or emotional gutting. It's not a fun space to live in a lot of the time. It's why I enjoy doing comedies. It's much easier, thinking of what rhymes with truck."
