Matt Damon and his wife, Luciana, took a walk in NYC yesterday afternoon. The couple hung out around home as Matt's latest movie opened in theaters across the nation. Contagion was number one at the weekend box office, unseating running champion The Help after a three-week winning streak. Matt was busy on the press trail for his Steven Soderbergh film, but the actor made sure to be in the Big Apple a few days ago when his daughters headed back to school. Steven and Matt will have a chance to get together again soon, as they're due to start shooting their Liberace movie with Michael Douglas.
