Jodie Foster's Flightplan, which is being boycotted by flight attendants' unions, ruled the box office for a second week by scoring another $15 million, besting buzzed-about sci-fi newcomer Serenity (with $10.1 million), Tim Burton's Corpse Bride ($9.8 million) and the crime drama A History of Violence ($8.2 million). Into the Blue, meanwhile, having placed fifth with a scant $7 mil, wants to remind pirating unions that it paints an awfully unflattering picture of treasure hunters.
