Upcoming from Pixar (2009 or 2010). Should be from Pete Docter.
Apparently it's a "coming-of-old-age story" about a seventysomething guy who lives in a house that "looks like your grandparents' house smelled." He befriends a clueless young Wilderness Ranger and gets into lots of alter-knocker altercations. Our hero travels the globe, fights beasts and villains and eats dinner at 3:30 in the afternoon.
