An unlikely band of scientists and soldiers join forces to save the world from certain destruction in this action-drama. As the world is struck with a variety of inexplicable phenomena -- attacks by enormous swarms of birds in London, the explosion of the Colosseum in Rome, a potentially deadly malfunction which forces the Space Shuttle into a Los Angeles riverbed, and the simultaneous deaths of 32 people with pacemakers in Boston -- a team of top scientific minds from around the globe is assembled to determine what has thrown the world into such a frenzy. Dr. John Keyes (Aaron Eckhart) makes the startling discovery that the Earth's electromagnetic forces have begun to collapse, thanks to a sudden lack of movement of the molten ore at the center of the Earth. If the planet is to be saved, the core of the Earth needs a jump start, and Keyes assembles a team to burrow to the center of the planet and bomb the insides back into action. Joining Keyes on this dangerous, last-chance mission are the brilliant but arrogant Conrad Zimsky (Stanley Tucci), French arms expert Dr. Serge Levesque (Tchéky Karyo, maverick researcher "Brazz" Brazzleton (Delroy Lindo), geeky computer genius Rat (DJ Qualls), and two no-nonsense military types, Commander Richard Iverson (Bruce Greenwood) and Major Rebecca Childs (Hilary Swank). However, as the crew digs deeper into the Earth, the more they discover what they haven't been told about their mission and what's really been causing the worldwide chaos. The Core was originally scheduled for release in the fall of 2002, but the movie didn't reach theaters until the spring of 2003 as special-effects experts perfected the film's more spectacular scenes.
