On the Upper West Side, as it turns out. Sources say Tim Blake Nelson, the actor, director, and sometime playwright who will shortly be seen onscreen with Billy Bob Thornton in The Astronaut Farmer, and his wife, actress Lisa Benavides, have been apartment-shopping, and look to have finally settled on a sprawling penthouse off the Broadway corridor for about $5 million. Their new apartment is in an old-school-gracious prewar and was put together from five properties, giving it views of the city in all four directions. Most accounts say that the couple lives primarily in Los Angeles, but the two aren’t exactly new to the neighborhood: City records show they once owned—and may still be hanging on to—a place on Riverside Drive. Listing brokers Deanna Kory and Karen Kelley of the Corcoran Group declined to comment on the sale.
