Great American Actors Robert Redford and Nick Nolte have teamed up for A Walk in the Woods, an adaptation of Bill Bryson’s 1998 travel memoir about hiking the 2,200 mile Appalachian Trail with his old friend Stephen Katz. The book combines the history of the trail with tales of Bryson struggling to get along with the often annoying Katz, and it feels like perfect fodder for a buddy road comedy.

From the looks of the movie’s first trailer, that’s exactly what it’s going for, right down to doing the same bunk bed collapse gag that Chris Farley and David Spade did in Black Sheep. The twist is that Redford is 78 and Nolte is 74, while Bryson was in his 40s when he walked the trail, so there’s quite a bit of a Grumpy Old Men vibe here. So far, it kinda works, in a comfortable, this-movie-will-be-on-basic-cable-a-lot way.

A Walk in the Woods hits theaters September 2.
