Goofs

The fictional "USS Charles Davis" that Admiral Engleberg commands is portrayed by at least three very different ships. It starts off as the Canadian HMCS Charlotte, then becomes the Australian HMAS Darwin, interspersed with shots of the foredeck and gun of a Ticonderoga or Arleigh Burke class destroyer. Finally it becomes a CGI version of the USS Arleigh Burke, with its gun and missile tubes replaced with a triple-gun turret.

The Sydney Opera House is crashed into several times, then is undamaged in subsequent shots.

While Jack and the Admiral are talking/arguing over an unconscious Rosie in the mechanical shark, her head gear appears then disappears when the camera angle changes.

When Jack is riding what appears to be a 2003-2005 YZ250/450, when he goes to kick it over, the film is backwards as the kick starter and exhaust are on the left side, and even more obvious, the name on the side reads AHAMAY instead of YAMAHA. From that point on, the film is correct and the kick starter and exhaust are where they should be, on the right-hand side.

Throughout the scene, there are standard motocross sized wheels, 21" front and 18" rear with knobbies. During the final scenes on the bike, it gets a set of 17" supermoto wheels and tires.

During the locker room scene between the black guy and the white woman, her hand is on/off his face between shots.

In the establishing shot of Sydney Opera House, the caption reads "Sydney Harbor", but as it is an actual place name it should have the Australian spelling of "Sydney Harbour".

In the closing sequence, US sirens are heard from first responder units in Australia.

In the opening scene where the 2 crew members are playing chess in the pilot house, the engine telegraph indicates the pilot is calling for "Slow Ahead", but the repeater showing engine room acknowledgment of the command is at "Stop". Also, the ship is navigating coastal waters with other ships around it but there is nobody at the wheel.

During all scenes featuring the reporter/photographer she's holding a black microphone, neither a wireless transmitter nor cable is plugged into it.

When Mecha Shark is attacked in the first 5 minutes of the movie and Rosie Gray (Elisabeth Rohm) reaches over to turn on the 'Eel Skin', the panel turned on is clearly labelled 'Klipsch' and looks to be a subwoofer panel.

The quote, "The Atlantic Ocean was on lock down today..." makes no sense whatsoever.

When the Megalodon leaps out of the water attack airplane,Because most airplanes fly at an altitude of 5-15 km Megalodon pellets require a speed of approximately 3600km/h when rising out of the water It's almost as fast as SpaceShipTwo.

The "USS Charles Davis" was a destroyer in the early 1900's decommissioned in 1933 and sold for scrapping in 1934. Therefore, the scene where they are aboard the "USS Charles Davis" is incorrect as the film is clearly not set earlier than 1934.

While the movie takes place in Australia the cars are driving on the wrong side of the street. In Australia, cars drive on the left.

Fifty one minutes in, when the movie cuts to Sydney for the megaladon's location, they use the standard Bondi Beach shot and follow it up with a shot of London Bridge, which is actually about 1100 kilometers away on Victoria's Great Ocean Road.

The first opening credits aerial establishing shot of "Alexandria, Egypt" is San Francisco. AT&T Park and the Transamerica Pyramid are both visible, among other landmarks.

When the reporter is telling viewers to call the number listed at the bottom of the screen, the country code given is 32 for Belgium instead of 61 for Australia.

The Admiral refers to the lost submarine as a ship; sailors refer to subs as boats.
