Too old to rock 'n' roll, but not to hike the Appalachian Trail
I rate movies according to what they are and aspire to achieve. This is a consistently amusing drama/adventure starring two seasoned veterans and it thoroughly delivers the goods as quality entertainment spiced with worthy mindfood.
Some people complain that Redford and Nolte were too old for the parts (they were 78 and 73 during filming) in light of the real Bill Bryson and Katz being in their 40s in the satirical 1998 biography, but without them the movie wouldn't have been made and, besides, they're eminently effective in the roles and drive home the point of out-of-shape, mature wannabe hikers.
It's vastly superior to Emilio Estevez' similar "The Way" (2010).
It runs 104 minutes and was shot along the Appalachian Trail in North Carolina, Georgia, Pennsylvania, Virginia, as well as Sharon, Connecticut.
