(at around 54 mins) When Epps is walking down the hall looking for Katie's room, she is clearly wearing the heart necklace which she has not found yet.

(at around 54 mins) Throughout the film, the doors to all the cabins are seen to open to the inside. Yet, when Epps is wandering the ship looking for Katie's cabin, all the doors in the hall automatically slam shut in a row and close from the outside. When Epps sees Katie's cabin door open, it opens to the inside.

(at around 14 mins) When the Arctic Warrior first collides with the Antonia Graza, it strikes just above her name on the bow. In the next shot, the Warrior is seen bouncing off the hull just aft of the bridge, and a final shot shows the Warrior backing away from the Graza near the stern.

(at around 1h 8 mins) When Epps is talking to Munder and Dodge next to the two water pumps draining the engine room, both the hard suction line and the flexible discharge line are in the water. The discharge line was previously thrown overboard by Epps and shouldn't be in the water.

(at around 58 mins) In the captain's cabin, the glass switches from the captain's right hand to his left between shots.

Maritime law on salvage at sea is not "finders keepers" as stated. In reality, salvage crews are hired, normally by the owners of the vessel, which then are awarded a salvage fee which is typically a percentage of the value of the ship and cargo. In this case, the crew would had to have contacted the Italian cruise line and - since they are close to Alaska - most likely the American Coast Guard. However, if the ship line that owned the Antonia Graza had no longer existed or the Italian government refused to pay (a government normally only gets involved if the ship is military or governmental), the ship would very well be worthless, even as scrap. Moreover, some lost ships (often the ones lost with a great loss of lives or during wartime) are often declared graves, and disturbing them is a crime. If that were the case, the crew would not only lose their investment but would also have to pay a fine before returning the vessel to its owners, without compensation.

(at around 43 mins) Gold bars of the size shown are much heavier than depicted.

(at around 44 mins) The gold Epps and Jack find has to weigh around 20lbs per bar, yet the salvage crew is able to wield it like a loaf of bread. When they open a crate, Captain Murphy runs his hands down the row of gold and one of the bars moves a bit which would not be possible because its weight. Also, a single crate has more than 23 bars of gold, totaling over 500lbs yet two men are able to lift it without mechanical assistance.

(at around 12 mins) When the Arctic Warrior finds the Antonia Graza, it is night time. The Arctic Warrior would not be running with the lights on inside the pilothouse because it makes it hard to see through the windows due to glare from the lighting inside the ship.

(at around 19 mins) When exploring the ghost ship for the first time, the team encounters a pendulum clock that's still working. There would never be a pendulum clock on a boat, because such clocks don't work at sea. The pendulum swing conflicts with the boat swinging and thus the clock would never tell correct time or even stop.

(at around 19 mins) When they first enter the ship, Maureen (Julianna Margulies) jokingly says "my name is Julie, I'll be your hostess". Julie is a character from The Love Boat (1977), not a mistaken use of the actress' real name.

(at around 23 mins) When the salvage crew first arrives on the Antonia Graza's bridge, Dodge makes a comment that she "must have run on full throttle 'til she was bone dry." Earlier in the film, after the massacre on the bow and Katie's screams, there is a shot of the Graza sitting dead in the water. However, it is possible that the soul-gatherer piloted the ship around the world looking for souls and then ran out of fuel.

(at around 1h 8 mins) When Epps breaks a cabin window and throws the pump discharge line out the window, the water is shown being discharged from at least five decks above the waterline. The engine room was below the waterline, and no one would run a hose up an extra five flights of stairs when they could run it overboard just above the water-line unless the cabins on the other decks were locked by their former residents/had rusted through floors/ were otherwise inaccessible. Continuing up another deck would be preferable to wandering the decks on the chance of finding an open cabin, as people generally lock the doors to their rooms when they are not in them.

The Antonia Graza is owned by the Italian line. However, when the salvagers find the ship, it is in the Bering Sea, which is by Alaska. The Italian line never ran ship anywhere near there. And Katie says that she was going to New York, which is on the other side of North America and Katie has an English accent. So the ship should have been on a transatlantic voyage but it was found adrift in the Bering Sea, though it is possible that the soul-gatherer piloted the ship around the world looking for souls before damaging the ship and forcing a stop.

(at around 46 mins) After the team decides to take the gold and leave the ship, one of them slaps the lid closed on one of the cases of gold which makes it move a lot. With the amount of gold in it that was shown, it would be too heavy to move simply by slamming the lid closed.

(at around 1 min) Though Francesca (the lounge singer) speaks perfect Italian during the rest of the movie, the song she performs during the title sequence ("Senza Fine") is sung in heavily-accented Italian. (Italian actress Francesca Rettondini is lip-syncing a non-Italian performer.)

(at around 12 mins) When the Arctic Warrior is searching for the Antonia Graza, it is shown traveling through a bad storm. There are many shots of the outside of the boat with driving rain and lightning; however, the sea remains flat and calm the whole time.

(at around 33 mins) Though the Antonia Graza is supposed to be an Italian ship, there are several glaring grammatical errors whenever Italian words are visible on screen. The most evident of these is the plaque sporting the phrase "Cabina di capitano" (outside the ship's captain cabin) instead of the correct "Cabina del capitano". Other visible errors include gibberish on a can of rat poison in the galley.

(at around 56 mins) Epps is frightened when she finds Katie's body hanging by her neck in the closet in her cabin. But a body hanging by the neck for 40 years, in a damp sea environment, would have rotted and fallen apart and to the floor. But finding a bundle of bones in clothing would not have been as dramatic or scary as finding an intact mummy hanging by its neck.

The ship is shown to have large round indoor aquariums in several places. The technology did not exist in the '60s to create this type of rounded acrylic.

(at around 48 mins) The sound of the propane explosion on the Arctic Warrior begins a fraction of a second before Greer's finger hits the switch.

The ship is supposedly caught up in a rotating current in the Bering Sea. North of the equator, this would be moving the ship in a counterclockwise direction, driving its right (starboard) side into the rocky islands at the edge of the current. As shown, the ship's left (port) side is at risk, meaning that the ship is drifting in a clockwise rotation. This would be the norm south of the equator, where the movie was filmed.

(at around 13 mins) In the sequence immediately prior to the Arctic Warrior finding and striking the Antonia Graza, at least one small ship or other structure is barely, but distinctly, visible on at least two occasions in the sea in the gloomy background. If this is the middle of open sea, they shouldn't be there.

(at around 24 mins) Captain Murphy's story of the Mary Celeste is largely inaccurate. According to him, it was a two-mast brigantine leaving Charleston, South Carolina, during the American Civil War. She carried a load of cotton for London, England. Fishermen off the coast of Tripoli found the ship under sail with no one on board; its last log entry was 59 days prior. Somehow an unmanned ship sailed through the Strait of Gibraltar and into the Mediterranean Sea.

In truth, the Mary Celeste left New York Harbor in late October 1872 with a cargo of 1,701 barrels of denatured alcohol bound for Genoa, Italy. She was found off the coast of Portugal, under sail yet abandoned, with its last log entry nine days before she was found.

(at around 16 mins) Murphy states that in the '60s, the Italians could not compete in speed so they built their ships to be extremely big and luxurious. That is factually wrong for two reasons: first, since the 1940s, Italian ocean liners were known for their speed (the most famous of them, the SS Rex, held the Blue Ribbon award for four years). Second, Italian liners built immediately after WWII were indeed very luxurious but not very big. The SS Andrea Doria (from which the film's Antonia Graza is modeled after) was barely 200 m long, a full 100 m shorter than the largest ship of its time, the RMS Queen Elizabeth.

(at around 25 mins) Murphy says the boat was moving at a certain number of "knots an hour". "Knots" means "nautical miles per hour" so "knots an hour" is redundant.

(at around 52 mins) The Italian in the ship's log is incorrect when Epps looks up Katie's entry. She is listed as "viaggendo solo". The word "viaggendo" is incorrect, and should be "viaggiando". Since Katie is female, the adjective "solo" should also agree and be "sola", so the entry should read "viaggiando sola".

The crew of the Artic Warrior are experienced marine salvagers. They would know that the Antonia Graza was NOT a boat, BUT a ship. YET they continuously refer to the Graza as a boat. This is something seamen would never do. They would only refer to her as a ship.
