How green will the box office wind up being this Father's Day weekend? Well, look no further than the predictions that Warner Bros.' The Green Lantern will rake in $50-60 million in its debut. (Fox is also opening the Jim Carrey comedy Mr. Popper's Penguins , but it's not expected to earn more than $10-15 million.) Still, $50-60 million barely amounts to chump change when one considers that the movie reportedly cost more than $200 million to produce, when the costs of 3D conversion are added to the official $150-million budget. Also this weekend, Woody Allen's new movie, Midnight in Paris , will move into 1,038 theaters, the most ever to screen an Allen film.
