Will Smith has a magic touch at the box office. Even when his films don't fare well with critics, they still pull in crowds. Smith's latest venture offers a contrast to his recent I am Legend and Hancock , and is more in line with The Pursuit of Happyness . In fact, his latest film, Seven Pounds , is directed by the same man -- Gabriele Muccino -- who steered Smith to an Oscar nomination in Pursuit of Happyness . In Seven Pounds , Smith plays a man who harbors a dark secret, and seeks redemption by trying to change the lives of seven strangers. Check out the trailer and see if this film makes your Christmas list of must-sees. The trailer is courtesy of Sony Pictures.
