EXCLUSIVE: Borat and Bruno helmer Larry Charles is set to direct the film adaptation of Bill Bryson’s best-selling memoir A Walk In The Woods, with Robert Redford and Nick Nolte starring. The script was written by Little Miss Sunshine‘s Michael Arndt, and it is aiming for a March start. Wildwood Enterprises’ Redford and Bill Holderman are producing with Route One Films’ Chip Diggins. The film is a road-trip comedy about an aging travel writer who decides to hike the 2,000-mile Appalachian Trail, accompanied by a long-estranged high school buddy he’s been avoiding for years. Along the way, the duo face off with each other, nature and an eccentric assortment of characters only to discover that some roads are better left untraveled.

“Growing up in the wilds of Brooklyn, you can see why I was the natural choice to direct A Walk In The Woods,” Charles said. “I didn’t see a tree till I was 27. I’ve pitched a lot of projects, but I’ve never pitched a tent. But A Walk In The Woods is not merely about a hike. It is an epic, intense, absurd journey through our collective past, present and future. A journey outward and inward. A journey into darkness but also into the light. And I am honored and humbled to take that walk with Robert Redford and Nick Nolte. Two true bonafide icons of American cinema. Does anyone have bug spray?”

Route One Films will finance through its partnership with Union Investment Partners in South Korea. The film will be executive produced by Route One’s Jay Stern and Russell Levine, and Kim Young-Don, the CEO of Union Investment Partners. IM Global is handling overseas distribution and WME Global is handling sales. Redford, Charles and Wildwood are all repped by WME.
