Men in Black (1997)

Visible crew/equipment: As K goes to tell Mikey to be quiet, the corner of the sound stage can be seen over his left shoulder.

Continuity mistake: When J holds the baby squid, his fingers protrude more or less depending on the angle. (00:44:40)

Sacha

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)

Sacha

Revealing mistake: When Arquillian is laying flat dead in the morgue, his pulse on his throat is very visible. (00:50:35)

Sacha

Continuity mistake: In the jewelry store, when J chases the farmer, the boots behind him swap from standing to fallen between frames. (01:03:35)

Continuity mistake: At the end of the film, Will Smith and Tommy Lee Jones blast the Bug, getting covered with entrails, intestinal contents, etc. Then in the next scene, when Jones is passing the neurolizer to Smith, they are both clean, while Linda Fiorentino is still covered all over. Absolutely nothing is mentioned in the film that indicates their clothing to have any sort of extraordinary qualities, which would make their garments unique. (01:27:30)

Other mistake: At the very beginning, when K disintegrates the alien Mikey, an MIB cover-up team arrives on the scene and approaches K at a distance of about ten meters (roughly 30 feet) ; whereupon K instructs them: "Give me a splay burn around the perimeter with holes at forty, sixty and eighty meters from right here! Thank you!" The team members disperse a scant few steps and use their flamethrowers and extinguishers on the cacti and undergrowth in the immediate area for five seconds. However, the distances K describes (forty, sixty, and eighty meters) would require the team laboriously dispersing hundreds of feet into the desert. But five seconds later, they're still only about 30 feet away from K when he says, "That's good! Thank you!" (00:07:55)

Continuity mistake: After Laurel is abducted and Jay tries to find her in one of the cabs, Kay brings the LTD around to pick Jay up. The LTD stops beside Jay in a position parallel to the white lines in the road. Jay gets into the LTD and when Kay drives off the LTD has noticeably changed its angle to the white lines even before it begins to move.

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.

Continuity mistake: When K and D are talking to Mikey, they are standing in a clearing with no grass on the ground. When Mikey spots the trooper behind him, he turns and starts running towards the trooper, and he is running down a pathway in the grass.When K shoots Mikey and he is blown apart, there is a shot from the trooper's point of view towards K and D, and the pathway that Mikey just ran down is no longer visible and K is no longer standing in a clearing.
