The Day After Tomorrow
Supreme silliness doesn't stop The Day After Tomorrow from being lots of fun for connoisseurs of epic-scale disaster flicks. After the blockbuster profits of Independence Day and Godzilla, you can't blame director Roland Emmerich for using global warming as a politically correct excuse for destroying most of the northern hemisphere. Like most of Emmerich's films, this one emphasises special effects over such lesser priorities as well-drawn characters and plausible plotting, and his dialogue (cowritten by Jeffrey Nachmanoff) is so laughably trite that it could be entirely eliminated without harming the movie. It's the spectacle that's important here, not the lame, recycled plot about father and son (Dennis Quaid, Jake Gyllenhaal) who endure an end-of-the-world scenario caused by the effects of global warming. So sit back, relax and enjoy the awesome visions of tornado-ravaged Los Angeles, blizzards in New Delhi, Japan pummelled by grapefruit-sized hailstones, and Manhattan flooded by swelling oceans and then frozen by the onset of a modern ice age. It's all wildly impressive, and Emmerich obviously doesn't care if the science is flimsy, so why should you? --Jeff Shannon

The Day the Earth Stood Still
A hallmark of the science fiction genre as well as a wry commentary on the political climate of the 1950s, The Day the Earth Stood Still is a sci-fi movie less concerned with special effects than with a social parable. A spacecraft lands in Washington, D.C., carrying a humanoid messenger from another world (Michael Rennie) imparting a warning to the people of Earth to cease their violent behavior. But panic ensues as the messenger lands and is shot by a nervous soldier. His large robot companion destroys the Capitol as the messenger escapes the confines of the hospital. He moves in with a family as a boarder and blends into society to observe the full range of the human experience. Director Robert Wise (West Side Story) not only provides one of the most recognizable icons of the science fiction world in his depiction of the massive robot loyal to his master, but he avoids the obvious camp elements of the story to create a quiet and observant story highlighting both the good and the bad in human nature. --Robert Lane

Independence Day
In Independence Day, a scientist played by Jeff Goldblum once actually had a fistfight with a man (Bill Pullman) who is now president of the United States. That same president, late in the film, personally flies a jet fighter to deliver a payload of missiles against an attack by extraterrestrials. Independence Day is the kind of movie so giddy with its own outrageousness that one doesn't even blink at such howlers in the plot. Directed by Roland Emmerich, Independence Day is a pastiche of conventions from flying-saucer movies from the 1940s and 1950s, replete with icky monsters and bizarre coincidences that create convenient shortcuts in the story. (Such as the way the girlfriend of one of the film's heroes--played by Will Smith--just happens to run across the president's injured wife, who are then both rescued by Smith's character who somehow runs across them in alien-ravaged Los Angeles County.) The movie is just sheer fun, aided by a cast that knows how to balance the retro requirements of the genre with a more contemporary feel. --Tom Keogh
