Men in Black (1997) - 3 questions

Question: When we first see MIB headquarters, K says that the little destructive energy ball thing is "a little practical joke by the Great Attractor." As far as I can tell, the Great Attractor is just a gravitational anomaly, so how could it play practical jokes?

Answer: Yes, "the Great Attractor" can refer to a specific anomaly in the Centaurus Supercluster, but that is a far cry from saying that the term can only refer to that specific anomaly. It is completely possible for a high-tech prankster and/or performer to use the name "the Great Attractor." It's like saying "the Boss" when referring to Springsteen. The term means a manager over a group of people in a place of work, but he can still use it as a stage name.

Question: When I watched both films in succession, I noticed the same person played both the man on desk at the morgue and Newton, the video store owner in the second film. Is there a reason for him being in both films?

Answer: The person in question is actor/comedian David Cross. According to the film's credits, these are not two separate characters, as he is listed as Newton for both films. I can find no official explanation to his return for the sequel, but it would appear that his character was not killed at the morgue by Vincent D'Onofrio in the first film, only incapacitated with that slimy stuff.

Question: When K and J are about to leave the police station, J says that he has a report to do. At that moment, his boss arrives and tells him he did a good report. Who did his report? It couldn't have been the MIB, because J was the only person who saw the entire chase.

Answer: The MIB - or K specifically - had already erased the memories of all the police that were involved to cover up the alien sighting. It stands to reason therefore that theyd already have a cover story in place - that is the report that the captain is reading, and for which he congratualtes J.
