Factual error: After returning to the Dursley's after the dementor attack It is dark, this shows again when Vernon puts Dudley in the car. However, the howler from Mathila Hopkirk says that at 6:23pm Harry performed illegal magic. As the side story shows it is a hot summer, it wouldn't get dark until way past 8pm. (00:04:53 - 00:07:20)
Suggested correction: Fairly certain the film was clear that the reason it got dark was because of the dementors, they have the ability to change the weather to depressive darkness.
Factual error: No army flight from Georgia to Iraq would cross central Mexico.
Factual error: After they arrive in Sarajevo they are driving through city and are observing demolished city. There is a red car parked behind three woman. That car is Chevrolet Spark (second generation) that was produced between 2005-2009. Film takes place in year 2000. (00:10:25)
Factual error: In the scene showing Septimus swimming underneath the water after having dived through Capt. Shakespear's cabin window, you can see Septimus holding his fighting knife in his right hand. After a stroke or two he lets go of the knife and it doesn't sink.
Factual error: The Human Torch chases the Silver Surfer into the Lincoln Tunnel at 29:35; the entrance shown is on the New Jersey side of the Hudson River (although they had just been in Manhattan seconds before, they were airborne and could have gotten there from the sky). When they collectively exit the tunnel at 30:01, they are still on the New Jersey side, as evidenced by the toll booth clerk who witnesses their flyby. While both the entrance and exit scenes are physically in the same a place, a large American flag was either pasted into the entrance scene or edited out of the exit scene, creating a slightly different visual element to two otherwise identical landscapes.
