Suddenly my old Fairfield County stomping grounds (Wilton and Norwalk) are part of the Hollywood-now cycle. The Dave Karnes character in World Trade Center (Paramount, 8.9) is shown watching the 9/11 tragedy on a TV set along with two or three coworkers at his job in Wilton, and now House of Sand and Fog director Vadim Perlman is in a legal skirmish over something that happened in a South Norwalk restaurant-bar. It sounds lame to bring this up, but if you lived in this neck of the woods and someone mentioned this to you at a party at someone’s home on Cheesespring Road, you’d smile and nod and go, “Yeah, interesting.”
