Visible crew/equipment: When a gremlin attacks the Mum from a Christmas tree, and the tree falls on top of her, you can clearly see a member of the crew with eyeglasses, wearing a red shirt, standing behind the tree pushing it forward on top of her. (00:54:30)
Visible crew/equipment: When Freddy falls over the banister onto the stairs near the end, notice the crash mat he lands on. (01:18:55)
Visible crew/equipment: In the scene where Bella walks toward the strangers on motorcycles, her mic wire is visible through her jeans. (00:32:10)
Visible crew/equipment: In the crushing room at the end of the film, Strahm is trying to open the box where Hoffman is. As it's descending into the ground, on the side of the box you can see the feet of a crew member with white sneakers moving around. It is not Strahm's feet: he's wearing black boots. No slow-mo is required.
Visible crew/equipment: When the fishermen start out on the hunt, Ben Gardner appears in a close-up leaning on the windshield at forward deck, while talking to his boatmate about how stupid some of the others are. In the next wide shot of the boats, Ben's green boat is towards the left of the screen, and the large reflector screen and camera, that are mounted to the bow of his boat, are visible in front of the forward window where Ben was seen in the previous shot. (00:30:25)
Visible crew/equipment: When the group was flying into the island, there's a shot of the plane flying in front of the cloud, and there's the obvious shadow of the helicopter that filmed that shot.
Visible crew/equipment: At the start of the film, just after the war exercise, when the Sergeant begins yelling at the recruits you can see the outline of his microphone under his T-Shirt. (It's not his dog tags because you can see the shape and dog tags are not shaped like that.)
Visible crew/equipment: When Ashley is running down the corridors before escaping back into her medical room, you can see the dolly that The Engineer chasing her is being pushed on. (01:04:50)
Visible crew/equipment: In the scene after Patrick Bateman's second encounter with the detective in his office, we see Bateman having sex at Courtney's apartment. After he rolls off her, Bateman approaches the large, stand-up mirror in the bedroom. In the upper right hand corner of the mirror, a boom microphone can clearly be seen moving around to pick up Christian Bale's lines. The next time we get the same long shot, the microphone is gone. (00:52:45)
Visible crew/equipment: When the ambassador and the photographer are in the cemetery getting attacked by the dogs there are men standing behind a tree. I'm assuming they're the trainers - they are located when the photographer is trying to hop the fence. Look in the back right hand corner - there are about two or three men standing there. (01:21:15)
Visible crew/equipment: During the scene when Lou Costello is reading the narrative on Count Dracula we see the coffin door open and the candle on top of the box starts to descend. By the angle of the coffin door the candle would have easily fallen to the ground. If you look carefully you can see a thin black cord attached to the candle.
