Revealing mistake: When Beatrice turns the sugar bowl over to dump the sugar into the glass, a barcode label and handwritten prop inventory number with the name 'Sony' can be seen on the bottom of the bowl. The film was made at Sony Pictures Studios. (00:15:15)
Revealing mistake: When J and K get into the car (a POS if memory serves) K makes a comment about J fastening his seatbelt, if you watch in the background out of J's window as they pull away there are a few people walking at an incredible rate showing that they filmed the scene at a normal speed then sped it up when put into the final cut. (00:40:40)
Revealing mistake: When K and J buy the "hotsheets" (newspapers) to look for information, the clerk who K gives the money to briefly looks at the camera. (00:44:00)
Revealing mistake: When Arquillian is laying flat dead in the morgue, his pulse on his throat is very visible. (00:50:35)
Revealing mistake: When the jeweler's ear pops-open, the angle changes and it gets replaced for a prop that looks nothing like the real ear. (00:54:35)
Revealing mistake: There is a scene where Agent J is standing on a car and shoots the "Noisy Cricket" at the fleeing Edgar. The camera shot is from inside the car and just before Agent J crashes through the windshield, you see a precut area in the glass. (01:01:25)
Revealing mistake: In the scene after J shoots the exterminator van off of the tow truck he shoots again. When the camera clips to the tow truck driving away, you can see the smoke generators emitting smoke from the curb. (01:03:50)
Revealing mistake: When J and K are knocked over by the roach near the end, when they land you can see a square of grass move. Shows that a crash mat is covered with a bit of grass to make the landing easier. (01:19:20)
Revealing mistake: When Will Smith throws a rock at the escaping Edgar alien, if you watch the rock after it hits the alien, it disappears after hitting the ground. (01:23:20)
Revealing mistake: When the alien takes off Edgar's skin, when he throws it to the top of the hole in the ground then drags it back, you can see its rubber skin. I read the correction too. And no. Human skin doesn't look like rubber glove material.
Revealing mistake: As K walks out from the car, saying "INS, Division Six", look at the road they just drove up. It runs a short distance, and ends at a hill of dirt. Presumably, the pile and the end of the road are at the sound stage wall.
Revealing mistake: When James Edwards (later, J) catches the alien in the beginning and has him next to a wall, the alien pulls out a "reverberating carbonizer with mutate capacity" to shoot J. A quick tussle, and the alien drops the gun. When the camera goes to a close up on the gun, watch carefully. You see it quickly fade out of view after it comes to rest, and replaced with a few burning sparkle effects to simulate disintegration.
Answer: The person in question is actor/comedian David Cross. In the first MIB film, Cross is listed in the credits as "Morgue Attendant," and he ends up glued to the morgue ceiling, presumably killed by The Bug. If he had survived, the Men in Black would have certainly neuralized him, anyway, and he would have no memory of the alien encounter or the Men in Black. In MIB 2, David Cross is listed as "Newton" (the video store nerd) who apparently recognizes K, because K had asked Newton to reserve a videotape for him at some time in the past. K made this video request before he ever met J, and then K neuralized himself after leaving a trail of clues leading to the video store. Newton remembers K, so Newton hasn't been neuralized in years. Therefore, Newton in MIB2 cannot be the same character as the Morgue Attendant in MIB.
