Time for some positive box office news! By the end of this weekend, Harry Potter and the Deathly Hallows Part 2 will pass the $1 billion mark in worldwide gross. Domestically, the film is already over $300 million, and will race ahead of Harry Potter and the Sorcerer's Stone in both North American and worldwide returns by Sunday or Monday to become the franchise's biggest hit -- 3-D bump, higher ticket prices and IMAX surcharges excepting. Still, well done, Harry! [THR]
