Now that The Dark Knight has broken practically every record (including the ones for world's longest fingernails and Olympic long jump) and outgrossed formidable competition like The Mummy: Tomb of the Dragon Emporer and Space Chimps, could its three-week reign as our No. 1 movie finally be nearing an end? According to Fantasy Moguls, Pineapple Express is on track to earn as much as $28.7 million over the next three days, while the latest Batman adventure will probably make another $27 million (bringing its overall gross to a not-bad $440 million). Obviously this is a close race, but if Knight does somehow manage to stay ahead and it can hold its own against Tropic Thunder next weekend, Vulture predicts it will be America's No. 1 movie through the winter and Paul Dergarabedian will have to talk about it every Sunday for the rest of his life.
