When Reese Witherspoon signed up to play Cheryl Strayed in Wild, she knew she wanted to be as real and truthful as possible.
"I had to make a choice when I decided to do the film on how much I wanted to bear," she told E! News. "I have a real story to tell here because Cheryl was completely honest when she wrote her book."
With that mindset, the 38-year-old agreed to film some naked scenes for the big-screen adaptation.
"It was scary and challenging," she added after signing up. "It's not just a movie about somebody walking. It's really about someone who feels profoundly hurt and lost."
In the highly anticipated film, which will be released Dec. 5, Witherspoon plays a former heroin addict who decided to tackle a 1,100-mile hike after experiencing several tragic events, mainly a devastating divorce caused by drug use and infidelity.
