Continuity mistake: At the beginning of the movie, when Serleena first lands on Earth, her ship crashes into the ground and creates a mound of dirt. When Harvey the dog comes over to check it out, the mound is gone. (00:04:43)
Continuity mistake: Before the alien transforms into a woman it flips the pages of magazine located inches away. When the alien starts to transform the magazine disappears. (00:05:10)
Other mistake: In the opening scene when Sarleena takes the Vic Secret model's appearance the tentacles are just completing her face when the guy grabs her. He had to have seen the tentacles "building" her as he was walking up to her. (00:05:50)
Factual error: In the beginning when Agent J is riding on Jeff (the huge subway worm) he has to duck out of the way of the lights that control the traffic in the tube. However, the traffic control lights are not in the ceiling of the subway, they are generally on the right side of the train. (00:07:55)
Other mistake: When Agent J. is riding the Giant Worm in the subway, you see him getting hit by a metal bar on the top of the tunnel smack right in the head at amazing speed, twice! Yes, twice that happened. And later, when he is sitting on the bench with his partner, you see his head looks completely untouched, no cuts, blood, scars, absolutely nothing. Certainly he would at least have a little mark, but nope, nothing but a little sweat. Does Agent J. have a hard head or what? (00:08:05)
Continuity mistake: When Jay is trying to tranquilize Jeff he gets hit in the head by a crossbeam which lays him back on Jeff's back. You can see that the syringe is not in his hands or his mouth, but when he sits back up he has it in his mouth again. (00:08:25)
Continuity mistake: When Jay and Tee are at the diner eating pie, when Tee starts to eat his pie a woman with a purple shirt and black skirt walks by. When Tee Starts to cry, a few seconds later, there is a shot of Jay and the same lady walks by again. (00:12:45)
Continuity mistake: When Agent Jay and Tee are talking in the diner, a young guy passes behind Jay towards Tee, but disappears when the angle changes. (00:13:10)
Factual error: When Jay and Tee are in the diner at the start of the film, it's 9pm (we know this because Tee started at noon and Jay set the neuralyzer to nine hours), and outside it's completely dark. In New York City at 9pm in July, the sky is not completely dark - the sun would just be setting. (00:13:20)
Continuity mistake: The entrance room (the large stone building off Battery Avenue) to the starport reverses between the two movies. In the first movie, the guard sits on the right hand wall as one faces the elevator, with a fan visible through a grille behind him, and a circular vent on the other wall. In MiB II, he is sitting against the left hand wall, but the fan and grille is still behind him, meaning it has changed walls. (00:17:15)
Continuity mistake: When Frank the dog is growling at the agent in the park his teeth are fine but later talking to Zed he is told he can have better dental. He smiles and his teeth are horrible. (00:23:50 - 00:31:10)
Continuity mistake: When Agent J drives to see the small, gold alien ship in the yellow tent, he steps out of his car and into a small amount of mud. His shoes already have mud around the soles and edges when he steps out. (00:24:30)
Visible crew/equipment: When Jay enters the tent in which the small alien craft had landed we can clearly see the camera man in the golden reflection. This happens twice. (00:25:00)
Factual error: When Jay and Frank go to Truro, MA, to get Kevin, as they drive in, the background shows the Post Office in front of a lighthouse. However, 1) There is no lighthouse in Truro, and 2) the closest lighthouse is in North Truro, and this lighthouse (the Highland Lighthouse if you're wondering) doesn't even remotely resemble the lighthouse behind the post office. This means that either the shot was filmed in a different place than they say it was, or the background was digitally animated. (00:26:14)
Other mistake: When Jay opens the post office sorting machine and we see the multi-armed alien, there is a stereo playing rock music quite loudly. There's also a hole on the other side of the machine (to fire the letters out of) - shouldn't we have been able to hear the music through that hole before Jay opened the machine? (00:28:10)
Revealing mistake: When Jay is at the post office looking for Kay, he's talking to him in the parking lot and Kay is sitting in a mailman's cart. Jay says something to Kay, and Kay punches him, but you can see that he didn't touch him, especially since Jay reacts to the hit a split second before it happens. (00:28:45)
Continuity mistake: When Jay is giving Kay his favorite gun "little cricket" he is seen holding it by the lower part of the handle. The camera angle changes and he's holding it differently. The camera angle changes again and he back to holding it by the lower part of the handle. (00:31:45)
Visible crew/equipment: When Serleena is at MIB headquarters to give her credentials, the dolly shot shows an aquarium with an alien in it on which a boom operator and a crew member walking are reflected. (00:34:04)
Continuity mistake: When J and Kevin get flushed they end up in 2 cans in times square. In the long shots the cans are the same height, but in close ups, Kevin's is slightly shorter than J's. (00:35:30)
Continuity mistake: After being flushed, the amount of water on J's chin increases in the close-ups, but decreases in the wide angles. (00:35:35)
Answer: The tiny globe is an entire alien world. His small investigative action threatens to destroy them all.
