When aliens in enormous spacecraft suddenly arrive in Earth's atmosphere and start blowing things up, it falls to a cocky pilot (Will Smith) and a goofy scientist (Jeff Goldblum) to save the planet from total destruction. With plenty of action, special effects sequences and pithy one-liners, Independence Day is one of the '90s' best popcorn flicks. Bill Pullman co-stars as the gung-ho president who urges his citizens to fight back.
