Factual error: While Dr. Brazzleton is turning the hydraulic gear, his glasses fragment. If it was hot enough in his helmet to fragment his glasses, then his face should've been burned. (01:44:45)
Continuity mistake: In the scene near the end where they are shooting across the F-115 carrier, you can clearly see about 15 to 20 jets parked on the carrier, the camera goes in the carrier for 50 seconds to a minute, then the camera shoots outside of the carrier and you can see that there are only 5 to 7 jets parked. (01:55:15 - 01:56:20)
Other mistake: At the end of the film when the carrier battle group is searching for the deep earth team the carrier captain is wearing a baseball cap which reads "CVN-72 USS ABRAHAM LINCOLN". In the credits he is described as "USS CONSTELLATION CAPTAIN" but in the acknowledgments it thanks the captain and crew of USS ABRAHAM LINCOLN. (01:55:45 - 02:03:45)
Suggested correction: It seems this mistake has more to it. Because there are no external shots showing exactly what carrier it is by the hull number, there is no way to tell on screen what ship it is, besides the radar dishes on top suggest it is a Kitty Hawk class carrier (so it's the Constellation). The end credits list both ships, but on screen they say it was the Lincoln, so the credits should say the USS Abraham Lincoln Captain. I don't know why they would credit the Lincoln crew if they only used the name on their ball caps.
Factual error: When 'Rat' is trying to hack into Project Destiny control, he gets several '404' errors, but '404' is page missing, not access denied. It should say '401- Access Denied'. (01:56:19)
Factual error: At the very end of the movie when the credits are rolling you see a panned view of the earth. The earth is rotating the wrong way. (02:00:50)
Character mistake: The word "Storyboard" in "Storyboard Artists" during the end titles is misspelled "Stroryboard". (02:05:00)
Continuity mistake: On the ship, Dr. Zimsky reveals that project DESTINI is an acronym and that the last letter is "I" and not "Y." (INI standing for INItiative). When Rat is at his computer, he goes to the website for Project Destiny, with a "Y" and not an "I." This same thing happens when the Project Destiny subtitle flashes across the screen.
Plot hole: How do they maintain communication between the ship at the centre of the earth and the surface? There's no wire, and radio waves can only travel any distance without obstacles, and the earth's crust would be a pretty hefty obstacle...
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.
Plot hole: When the crew's vessel gets stuck in the giant geode and the crystal jams the 'impeller', the magma begins to fill the chamber. They see it melting the crystals, yet they frantically continue working to free the crystal from the impeller and lose a crewman...and yet when they get back in the vessel, the magma indeed melts out the crystal that jammed the impeller. With 2 geologists onboard you would think they'd know that.
Suggested correction: At no point do you see any of the crystals melting.
Factual error: When Victor and the crew are 2600 miles below the surface and Rat is trying to let Dr. Keyes know that Project Destini is going to happen, he contacts the ship via radio and even transfers computer data to the ship. This would be completely impossible because the ground would block any radio signals from reaching the ship. By the time the ship had reached about a mile down, there would be no radio contact whatsoever, no matter how powerful their transmitter was. Audio communication would be unfeasible too - the ship would make too much noise cutting through the earth to allow for any communications to be transmitted through solid rock.
Continuity mistake: At the end of the movie when they are looking for the survivors they have no signals and decide to give up. Rat is upset, we see a close up of him and his hair is long in the back. The next scene he is walking on the deck of the ship, he figures out the signal and calls to the general waving his arms and screaming. We see him in close up again and his hair is very short in back. Did he get a haircut on the way to the deck?
Factual error: When they realize they need to make the last nuclear explosion 30% bigger, they simply pull the fuel rods from the reactor and set them next to the bomb. This is ludicrous, a nuclear bomb is a carefully engineered piece of equipment, with carefully shaped charges imploding the radioactive material. Setting some fuel rods next to the bomb will accomplish nothing.
Suggested correction: By adding the fuel rods, what they did was not alter the initial reaction to the charges. What it does is amplify the reaction after the charges have gone off. Adding more reactive material increases the size of the blast.
This would have merely added more neutrons in the vicinity of the bomb's core, causing it to go prompt critical before the implosion charges could compress it. The result would be a fizzle.
Revealing mistake: When the boats are searching for the 'virgil' in Hawaii, we see a shot with all of them supposedly going full speed through the water - and their anchor lines are down.
Deliberate mistake: In the scene with the first demonstration of the digging laser, they dig/blast quite a hole in the mountain. Even assuming the laser can very easily shatter the rocks substance, still the debris would have to go somewhere, yet there appears to be none. And the amount of power needed to convert matter into energy is not practical.
Continuity mistake: Just before the shuttle stops in front of the bridge, we can see the worker being "touched" by the shuttles shadow. In the subsequent shot we can see the shuttle is too far away from the bridge for this to happen.
Continuity mistake: When Beck is in the command section of the ship with Zimsky and the rest of them in the weapons center, we can see that the screen she is looking at shows a shot of the black stuff coming towards them. The shot changes but then when it comes back to the screen, you can see the exact same footage used a moment ago.
Factual error: When Becca is waiting to be called before the flight review board and while standing in front of the board she is wearing earrings that hang below the bottom of her ear lobes. Military regulations only allow small spherical conservative earrings centered in the middle of the ear lobe.
Suggested correction: NASA Air Force actually are given special exemptions that are required by traditional military personnel.
Factual error: In the very first shot of the movie David's watch shows an invalid time. If it were 10:30, the hour hand would be between 10 and 11. The hour hand is exactly at the 10:00 mark even though the minute hand is at 30 minutes.
Suggested correction: There are actually watches where they design it so that the hour hand jumps from hour to hour as the minute hand travels. This is to aid some people in reading watch dials that have trouble otherwise.
Factual error: The scientists were surprised that the space suits were able to withstand the intense pressure encountered when they were walking around in the geode 500 miles below the surface of the earth. They should have been - the suits were made of flexible materials. No matter how heat resistant they were they would have to be completely solid (like the white deep-sea suit worn by the bad guy attacking Bond in "For Your Eyes Only") to provide protection from thousands of pounds per square inch of external pressure. The scientists should have been crushed like eggshells the second they stepped off the ship.
