The best movie opening on this Fourth of July weekend is, appropriately, an independent film.
"Snowpiercer" is an eye-popping, thought-provoking and entirely original post-apocalyptic action drama. In a near-future where the Earth is barren and frozen (thanks to a botched attempt to cure global warming), the last remnants of humanity live on a train that's constantly circumnavigating the planet. The train is split by economic classes, with the rich up front and the rabble in the rear. That rabble, led by the reluctant warrior Curtis (Chris Evans), plots revolt, and hatches a daring plan to get to the front of the train. Korean director Bong Joon-ho ("The Host"), making his English-language debut, plants surprises in every train car, with dynamic action and nail-biting tension that grips you to the end of the line.
