Factual error: The ship, VIRGIL, is diving straight down from the crust to the core. Although the interior of the ship pivots to make the cockpit perpendicular to the descent, the ship itself is "digging" straight down so when people move from compartment to compartment they should be climbing up and down rather than simply walking back and forth.
The Core (2003)
Plot summary
Directed by: Jon Amiel
Starring: Stanley Tucci, Aaron Eckhart, Bruce Greenwood, Richard Jenkins, Hilary Swank, Delroy Lindo, Tchéky Karyo, DJ Qualls
The molten metal core of the earth is slowing down and will eventualy stop, and the magnetic field of the earth, which is driven by the spinning core, is dying as well. This is a very bad thing, since it is the magnetic field of the earth that deflects large ammounts of radiation and radioactive particles from entering our atmosphere. The main characters build and pilot a vessel capable of drilling in to the center of the earth, where they have a plan to dettonate a nuclear device whose shockwave will hopefully jump start the earth's core. Thing's don't go as well as planned, and our heroes have to race against time to find a solution while the military on the surface plans to use "plan B," a plan that is less likely to fix the core, and will also kill our heros in the process.
More mistakes in The Core
Dr. Josh Keyes: So what's this about then?
FBI Agent: We don't know. You have higher security clearance than us.
Dr. Josh Keyes: I have security clearance?
FBI Agent: Yes sir, we're just here to take you to your jet.
Dr. Josh Keyes: I have a jet?!
Trivia: If you look closely with time-frame advance during the pigeon scene you will see a fish "flying" into a window instead of a pigeon. (00:08:35)
Question: The heroes manage to get the core spinning again by detonating 5 200 megaton nuclear bombs. In real life, wouldn't it take hundreds of 200 nuclear bombs to get the core spinning again?
Answer: No number of nuclear weapons would have an effect on the movement of the Earth's core. The bombs in the movie are just there as part of the plot. The Core is a hysterically unscientific movie. It's still great fun though.
