First announced last July, we finally have out first look at director Jean-Marc Vallee "Wild," starring Reese Witherspoon. The film, based on the best-selling book "Wild: From Lost to Found on the Pacific Crest Trail," tells the true story of Cheryl Strayed - a 26-year-old recovering heroine addict that embarked on a 1,100 mile journey of self-discovery along the famous Pacific Crest Trail. 

"I was failing in so many ways in my life, and my biggest fear was that I would fail again on this trip," Strayed told Oprah Winfrey. "I simply could not fail. I was too proud to call my friends and say, 'You know how I was gonna hike that trail? I didn't do it.' So, no matter what, no matter what, I had to get that pack attached to me and go. It didn't feel good. It felt terrible. It was really painful. But I had to do it, and now I see why: I needed to carry that heavy weight. I needed to carry the weight that I couldn't bear. That's what 'Wild' is about. It's about how we bear what we cannot bear."

Starting last October, director Valee (who just came off a big critical win with "The Dallas Buyer's Club") shot "Wild" in various areas in Oregon, including Ashland, Bend and Crater Lake National Park. The 51-year-old is adamant about capturing his subjects using natural light, a technique he says allows his actors to better lose themselves on set.

"They’re not under the impression that they’re acting with the hotspots and feeling the heat from spots, having their marks — there’s no marks, there’s no heat, just walking to real places and shoot the thing and try to touch people and try to make it real, so this approach is perfect for that."

"Wild" is slated for Dec. 5th release. Check out the first trailer below.
