The Core

The Core is a 2003 American science fiction disaster film directed by Jon Amiel and starring Aaron Eckhart, Hilary Swank, Delroy Lindo, Stanley Tucci, D. J. Qualls, Richard Jenkins, Tcheky Karyo, Bruce Greenwood, and Alfre Woodard.

The film focuses on a team whose mission is to drill to the center of the Earth and set off a series of nuclear explosions in order to restart the rotation of the Earth's core.

The film was released on March 28, 2003, by Paramount Pictures. It received mixed reviews from critics and grossed $74 million worldwide with a production budget of $85 million.

Plot
Several small, disparate incidents involving the Earth's magnetic field cause scientists led by geophysicist Dr. Josh Keyes and scientists Dr. Serge Leveque and Dr. Conrad Zimsky to conclude that the Earth's molten core has stopped rotating. Unless restarted, the field is set to collapse within months, exposing the surface to devastating solar radiation.

The U.S. government backs a secret project to build a vessel to drill to the core and release nuclear weapons to restart the rotation. They utilize the work of Dr. Ed "Braz" Brazzelton who has developed "Unobtainium", a material that can convert extreme heat into electricity, as well as a laser-based high-speed drilling array.

NASA pilots Commander Robert Iverson and Major Rebecca "Beck" Childs are enlisted to pilot the multi-compartment vessel Virgil, while computer hacker Theodore Donald "Rat" Finch is brought on to both keep news of the pending disaster and their attempt to restart the core off the Internet.

Virgil is launched through the Marianas Trench and makes its way through the crust. While traversing the mantle, the team accidentally drills through a gigantic empty geode structure, damaging the lasers when it lands at its base. As they traverse outside the ship to free the vessel, the geode is flooded with magma, and Iverson is killed by a falling shard. The rest return in time as Virgil continues its descent.

Further down, as Virgil passes through a field of enormous diamond formations, one of them breaches the last compartment housing the detonation timers for the nuclear charges. Leveque sacrifices himself to ensure the others have the charges and launch codes before the compartment is crushed.

The team reaches the molten core and realizes it is much less dense than previously thought, throwing off their calculations on restarting its motions. Communicating with the surface, overseer of the operation Lieutenant General Thomas Purcell, orders them to abandon the effort and return immediately as they plan to use a secondary protocol to restart the core. Finch is secretly communicating with the Virgil team and learns that this secondary protocol is the top-secret project DESTINI (Deep Earth Seismic Trigger INItiative).

Keyes discovers Zimsky was a lead scientist on DESTINI, a U.S. tectonic weapon that, when first tested, stopped the core's rotation. Finch redirects power from DESTINI to prevent Purcell from reactivating it, as Keyes fears that could destroy the Earth instead of restarting the core. Meanwhile, destructive events, including a lightning storm in Rome and a burst of ultraviolet rays that destroys the Golden Gate Bridge, alert the world to the situation.

On Virgil, the remaining team plans to place an explosive in each of the remaining compartments, release them, and time their detonations in an exact sequence to trigger the core's rotation through constructive wave interference. However, the override mechanism to permit detachment of each compartment is located in a dangerously hot section of “Virgil”, and Brazzelton dies in sacrificing himself to engage it.

As they set the charges, Keyes and Zimsky realize that they need more explosive power than previously thought and in their race to adjust timings, Zimsky becomes trapped in a detached compartment. Keyes uses Virgil's nuclear power source to provide the additional energy for the final detonation. While it leaves the main compartment powerless and Keyes and Childs trapped, the other explosions successfully restart the core's rotation.

Keyes recalls that the unobtainium shell can convert heat and pressure to energy, and the two of them wire the shell directly to their systems in time to power the craft and ride the pressure wave out of the core and towards the surface through tectonic plates, eventually breaching into the ocean floor near Hawaii. Due to the much lower heat and pressure in this environment, Virgil no longer has sufficient power to establish communications. The government searches for them, and Finch, tracking nearby whale sound, realizes that the Virgil crew are using low-power ultrasound to draw whales nearby. Keyes and Childs are soon rescued.

In the aftermath, Finch uploads information about Virgil and its team and the classified information about DESTINI across the Internet, causing the world to revere the crew as heroes.

Production
The Core began development in the late 90s under producer David Foster for Paramount Pictures and was one of several Journey to the Center of the Earth inspired projects in development at the time along with Inner Earth at 20th Century Fox and a straight adaptation of the novel at Walt Disney Pictures. Initially Peter Hyams had been announced to be in final negotiations to direct. In September 2001, it was announced Jon Amiel had signed on to direct. That same month, it was announced Aaron Eckhart had signed on to star in the film with co-star Hilary Swank joining the following month in October.

The Core had out-to-sea scenes, starring USS Abraham Lincoln (CVN-72), with full support of the US Navy.

The original plan for the shuttle landing scene had been for Endeavour to attempt a landing at Los Angeles International Airport with the shuttle coming to a halt on the nearby beaches. However, due to the events of September 11, 2001, the crew was not allowed to film at LAX. The scene was therefore rewritten with Endeavour landing in the L.A. River.

Reception
The Core garnered mixed reviews from critics. On Metacritic, another aggregation website, the film has a weighted average score of 48 out of 100 based on reviews from 32 critics, indicating "mixed or average reviews". In his review, Roger Ebert gave the film two and a half stars out of four and said "I have such an unreasonable affection for this movie, indeed, that it is only by slapping myself alongside the head and drinking black coffee that I can restrain myself from recommending it."

The film grossed $31.1 million in United States theaters, and another $43.0 million overseas for a total worldwide gross of $74.1 million against a production budget of $85 million.

Several reviews cited the numerous scientific inaccuracies in the film. Elvis Mitchell of The New York Times said, "The brazen silliness of The Core is becalming and inauthentic, like taking a bath in nondairy coffee creamer. The Earth core's inability to turn is mirrored in the cast's inability to give the picture any spin." Kenneth Turan of the Los Angeles Times was a little more forgiving, saying, "If The Core finally has to be classified as a mess, it is an enjoyable one if you're in a throwback mood. After all, a film that comes up with a rare metal called unobtainium can't be dismissed out of hand."

In response to criticism of his screenplay's lack of scientific realism, screenwriter John Rogers responded that he tried to make the science accurate, but expended three years fighting "to get rid of the ... dinosaurs, magma-walks in 'space-suits', bullshit-sci-crap sources for the Earth's crisis, and a windshield for the ship Virgil."

On March 30, 2009, it was reported that Dustin Hoffman was leading a campaign to get more real science into science-fiction movies. Hoffman is on the advisory board of the Science & Entertainment Exchange, an initiative of the United States National Academy of Sciences, intended to foster collaborations between scientists and entertainment industry professionals in order to minimize inaccurate representations of science and technology such as those found in The Core.

In a poll of hundreds of scientists about bad science fiction films, The Core was voted the worst.

On February 21, 2010, The Guardian ran an article about American professor Sidney Perkowitz's proposals to curb bad science in science fiction movies. In the article, Perkowitz is said to have hated The Core. "If you violate [the coherent rules of science] you are in trouble. The chances are that the public will pick it up and that is what matters to Hollywood. The Core did not make money because people understood the science was so out to lunch," he added.
