Corrected entry: In the scene when the alien ship crashes into the truck, it hits it from the side, and therefore would not split it perfectly; instead it would probably cut it in half and the 2 halves would both face diagonally.
Corrected entry: In the scene where Will Smith (prior to becoming a MiB) follows the perp/bug into the Guggenheim, Will smashes a glass door. An alarm would have gone off (even a silent one) and guards would have come running. Not to mention the fact that there was no visible security around the museum, inside or out. It was deserted, as were the streets. This is NYC; come on.
Corrected entry: In the scene where Will Smith and the soldiers are being tested to become Men in Black, they are in the shooting range. All of the people there shoot off almost their entire magazine at the targets. Yet in the next shot one alien only has four neatly spaced holes in him and the others don't appear to have many if not any holes in them. I guess these guys are pretty bad shots.
Corrected entry: In the beginning the agents wear Immigration and Naturalization Services patches, drive Border Patrol vehicles, and use Customs badges. All three were diffrent agencies at the time the movie was filmed.
Corrected entry: When the "Edgar" alien escapes from the building with the lady, he jumps very high out of window and up onto the street. But when he is trying to leave planet earth, why does he climb up the tower if he can jump that high or scramble up the side of buildings, like the alien at the beginning?
Corrected entry: In the end when the bug leaves with his UFO, the 2 MIB are going to shoot it down. When they fire, Will is on the left side. After the shot he is on the right side.
Corrected entry: In the scene where Edgar's skin gets inhabited by the alien bug, and goes back into the house, he pulls his skin back to make it stop hanging from his bones, in the next shot, he appears to still be holding it back, but when he lets go, it is very apparent that he was only holding his hair.
Corrected entry: The Arquillians threaten to destroy the Earth if they cannot retrieve the Galaxy. But where is Griffin's Arc Net Shield (MIB 3) which protects earth from alien invasions?
Corrected entry: When the Arquillian battle cruiser appears above Earth, all of the other aliens on Earth leave. Later, K tells J that "there's always an alien battle cruiser or a Corellian death ray or an intergalactic plague that's about to wipe out life on this miserable little planet." If that's the case, shouldn't the aliens always be leaving, or just never come back at all?
