Visible crew/equipment: Watch carefully the scene where the raptors enter the kitchen (that angle where you can see almost the whole kitchen while raptors are coming in from the far away door). As the first raptor enters the kitchen, you can see someone grabbing its tail to hold the puppet-thing steady. (01:44:40)
Visible crew/equipment: In the finale, Jessica runs over to Jason from behind and she stabs him in the heart with the dagger. Then, Jason lashes back and hits Jessica, and she goes flying backwards. Absolutely anyone can see the large blue crash mat that she lands on (cropped/edited out in some versions). (01:20:25)
Visible crew/equipment: When John Reynolds grabs his son from the clothing and the camera zooms in, you can see the shadow of a crew member in his left arm. (00:21:15)
Visible crew/equipment: When Phoenix falls through the glass at the museum into the LA exhibit, you can see him sliding down a safety rope. His feet are even in the position to be sliding down the rope. (00:49:15)
Visible crew/equipment: When the bad guys are pulling up to Rainer's mother's house, the shadow of the crane, camera and operator is visible on the road, on the left side of the screen. This is about three quarters of the way through the movie.
Visible crew/equipment: During the first fight with Robocop, the Ninja makes some jumps, in one of these you can see how the floor is an elastic surface.
Visible crew/equipment: When the alien ship is lifting up the Coneheads in their red car and the two Federal agents with its magnetic gripper, as they get closer to the ship's lights, you can see safety wires, either for the car or the two men.
Suggested correction: What you're seeing is the car's antenna.
Visible crew/equipment: When Mario is telling Luigi about getting a call from the café for the plumbing job at the start of the film, watch the cabinet with the glass doors behind Luigi. At one point, you can see the reflection of a crew member in a short-sleeve shirt for a few seconds.
Visible crew/equipment: When Travis is lying on the exam table, you see the aliens ripping his clothes off. But you see the arm of one of the crew tearing his pants off.
