Corrected entry: The sphere says that the attacking aliens' ship will leave if the alien queen is killed, even though moments before the sphere said that no one has ever defeated a queen. (01:00:00)
Corrected entry: When the new president talks to the world on shortwave radio, some kids are adjusting a TV antenna in one shot. Shortwave radios wouldn't work with TV antennas, they use two significantly different frequencies. Shortwave is a much longer wavelength and would require larger antennas to work.
Corrected entry: It was quoted in the film a number of times that the "Harvester Ship" was 3000 miles in diameter, ("It's over the Atlantic." "Which part?" "All of it.") yet there was apparently no problem flying to the centre of the ship in 3 minutes, and back.
Corrected entry: When David and Catherine are heading to the alien city destroyer in Umbutu, which used to be part of the Congo, they are surrounded by desert landscape similar to the southwestern US. No such landscape exits anywhere in the Congo. The country is covered in rainforests and grasslands. You can even see the Sandia Mountains which are in New Mexico in some shots.
Corrected entry: In the scene where Singapore is destroyed, the Fullerton Hotel is beside the Museum which was beside the Marina Bay Sands. In actuality, they are far from each other, and there is no Singapore Ferris wheel or Singapore Flyer.
Corrected entry: In this film the aliens are said to be operating with a hive mind, and are all telepathically linked to the alien queen on the mothership. It is also stated the mothership from the first film also had a queen that was never seen. If that is the case, then there would not have been any need in the first film to use Earth's satellites to coordinate the attack.
