Corrected entry: When Edgar stabs the Arquillians in the neck, they appear to die instantly from their wounds.

Corrected entry: In the pawnshop right after Jeebs' head grows back, K tells him, "I want you off the next transport off this rock or I'm going to shoot you where it don't grow back". Yet Jeebs appears in the next movie. (00:20:35)
Corrected entry: When Tommy Lee Jones and Will Smith are walking through the hallway, right after they're done with the gun test where Smith shoots the little girl, Tommy Lee Jones says "this way" and they turn into the hallway.

Corrected entry: When K reveals MIB's existence to J, J replies that K has been reading too many supermarket tabloids. K's response to this is to praise such tabloids as great journalism.

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: When K and J are leaving the NYPD station, J says he has to write a report. Then his boss walks past and compliments him on a good report. Who wrote the report? J was the only person who witnessed the whole chase.
