Blooper

The ship constantly changes from the moored Queen Mary to a CGI model of the original Titanic and back.

After the three characters escape out of the top of the elevator, the two women go up the ladder first. When they reach an upper floor, the man who was below them leads the way and opens the doors.

In the elevator, Amy takes off her top and gives it to Kelly. Moments later, Amy is wearing her top again.

When the ship is about to depart, a large amount of red paint shows on the hull above the water line. That means the ship, which should be fully loaded, is riding fairly high in the water. The red is gone in subsequent shots.

When the ship is in dock, its name is clearly visible on the bow. When the ship is portrayed in CGI, the name on the side is missing.

Someone says the tsunami is moving at 800 miles per hour, faster than the speed of sound (768 mph). According to the NOAA, tsunamis travel approximately 475 mph in 15,000 feet of water, which is about the average depth of the ocean.

While climbing out of the elevator, presumably up, one woman's hair hangs straight in front of her face, instead of hanging backward. That means they're walking horizontally instead of vertically.

The ship is supposed to be a replica of the original Titanic, yet the none of the interiors are the same, and the staircases are very plain.

In the bridge scene, the captain and second officer (with two stripes on his sleeve) are wearing hats with leaf-shaped insignia in the visor. That is reserved for senior officers, which the second officer is not.

A seaworthy Titanic replica would not have the same type of propulsion as the original ship. Due to modern shipping regulations, the propulsion system would consist of azimuth thrusters and bow thrusters.

Tsunami waves are barely noticeable in mid-ocean. They only increase in height near the shore, where the ocean gets shallower. That also causes them to crash and sweep away everything along their path.

Amy receives a phone call while stuck in an elevator, on a boat in the middle of the Atlantic. Land-based mobile phone service drops off about 4 miles from shore, but many cruise ships offer service at sea. It's expensive without a package; AT&T Wireless charges $3/minute for calls, $.50 per text, and $2.05/mb for data. The original Titanic had a telegraph on-board, and passengers could send and receive messages for $1 per word.

When the propellers stop, the ship stops almost immediately. Even if the propellers were put into full reverse, the ship would take about half a mile to slow to a stop.

During the panic scenes, a passenger runs along the deck from left to right and passes a line of windows, which reflect shore lights and buildings. The ship is supposed to be in the middle of the ocean.

When the initial wave hits the Titanic II, everyone in the dining room is tossed around, but the tableware says still. Even the wine in the wineglasses doesn't move.

Engine 1 blows when the ship hits 50 knots. The cut-away shows an old engine in an old ship. It supposed to be a new ship on its maiden voyage.

At 50 knots (around 60 mph), the wind on deck would be intense, yet the actors' hair remains undisturbed.

As the passengers look down to the people on shore while leaving the port, shadows of palm trees are visible. In the next scene, the ship cruises past the Statue of Liberty in New York, which has no palm trees.

When Amy finds the wounded nurse in the clinic, she covers the nurse's wound with a credit card and tape, despite having medical training and a clinic full of supplies.

The ship's owner would not be calling the shots on the bridge and arguing with the captain. A captain who was in that situation where lives were at stake would have the owner removed from the bridge.

The ship owner steers people to the elevators during the evacuation, even though standard practice is not to use elevators in an emergency.
