There's a Robert Redford interview in the Friday, 23 Jan, Wall Street Journal. At the very beginning the WSJ asks, "What are you working on...What's your next project?"
Redford responds, "I have three competing projects...A third is based on a Bill Bryson book, "A Walk in the Woods" and was meant for me and Paul (Newman) to do, about two older guys who want to do something challenging and decide to hike the Applalachian trail (sic)."
That's all...not much...but at least it seems to still be on his 'to do' list...
