No film had presented the destruction of the Earth on such an epic scale before this preposterously successful smash-hit sci-fi adventure came along. Of course, when we say Earth we really mean the USA - the rest of the world barely gets a look in. The story is simple: gigantic alien spacecraft hover above major cities and set about destroying everything below. Those plucky Yanks, however, won't go down without a fight. There are subplots focusing on the fate of ordinary folk, but most of the effort goes on the mind-boggling set pieces. Such scenes of digital mayhem are now commonplace, but this provided the template, and the levelling of Washington here is still impressive. Will Smith's charismatic performance as a wisecracking fighter pilot helped make him one of the biggest box-office draws in the western world, while Jeff Goldblum delivers a variation on his boffin role in Jurassic Park. Bill Pullman, meanwhile, manfully keeps a straight face as the beleaguered American President. Of the females, Vivica A Fox fares the best, although the likes of Mary McDonnell and Margaret Colin are largely wasted in supporting roles. But this is, after all, a special effects, not an acting, showcase, and a very entertaining one at that.

Strange phenomena surface around the globe. The skies ignite. Terror races through the world's major cities. As these extraordinary events unfold, it becomes increasingly clear that a force of incredible magnitude has arrived. Its mission: total annihilation over the Fourth of July weekend. The last hope to stop the destruction is an unlikely group of people united by fate and unimaginable circumstances.
