Redford on a trail in tame, congenial comedy

The lure of the wild has recently attracted an interesting batch of solitude seekers: Reese Witherspoon (Wild), Mia Wasikowska (Tracks) and Robert Redford, twice.

Two years after All Is Lost, Redford has swapped the sea for the woods, and wordless isolation for Nick Nolte. It's not a bad trade.

A Walk in the Woods is a broad and congenial comedy about two aged old friends trying to hike all 3,200-plus kilometers of the Appalachian Trail, from Georgia to Maine. It's light on its feet, even though its geriatric woodsmen are plodding and grunting.
