A Walk in the Woods (2015)

Robert Redford plays Bill Bryson, who decides to hike the more than 2,100-mile Appalachian Trail from Georgia to Maine, and Nick Nolte is the out-of-shape old friend who is the only person willing to come. Emma Thompson is the wife who will not let him go alone. The comic option, and the one for anyone who suspects they would be more Katz than Bryson. Ken Kwapis keeps it light and scenic rather than sharp, so watch it for two veteran actors bickering on a real trail, not for the bite of the book.
