Visible crew/equipment: During the vomit-eating scene the camera pans over the staircase and the cameraman casts a shadow over the banister. (00:46:40)
Continuity mistake: Through the vomit eating scene, there is vomit sliding and spilling down the outside of the glass bowl in some shots, but it is clean in others. (00:46:40 - 00:48:05)
Continuity mistake: In the vomit section: when they take the bucket to the boss, there are pieces of food on the top of vomit although they weren't there when they toke the bucket off, and the amount of vomit seems to be always the same when they drink it. (00:46:55)
Continuity mistake: Frank's collar alternates from up/down in the vomit eating scene. (00:47:00)
Continuity mistake: When all the aliens are eating from the bowl of vomit, one of the aliens has vomit around his mouth before eating from the bowl. (00:47:30)
Visible crew/equipment: When the collector, and the guys are standing on the stairs trying to escape, an alien walks down the hallway, and then a shot from over the banister swings to follow him. You can clearly see two red shoes and legs wearing jeans, standing by the banister - obviously the camera operator. (00:52:05)
Continuity mistake: During the shootout in the gardens, Frank is standing by a large green plant, which is in the middle of the gardens, with grounds, plants and paths behind it. In the next shot as he runs to the next plant, running behind the previous plant is a small wooden fence, which has suddenly appeared. (00:55:50)
Visible crew/equipment: There are many long wires clearly trailed across the lawns when Frank and the guys are shooting the aliens, to set off the squibs. (00:55:55)
Continuity mistake: Frank walks along the lawn and is standing on a patch of grass covered in brown leaves, when suddenly he gets fired at, so he leaps up (and then rolls to the floor) from green grass, with no leaves at his feet at all. (00:56:05)
Continuity mistake: In one shot as Frank is lying on his back, shooting, there are loads of leaves on the ground all around him, which suddenly disappear between shots. (00:56:35)
Continuity mistake: In one shot as Frank is lying on his back, shooting, his socks change from yellow and black stripes, to plain blue socks. (00:56:35)
Revealing mistake: When the chef swipes the knife, he hits another alien in the chest cutting him vertically. There is already a cut/rip in his shirt, where the chef rips. (00:58:45)
Continuity mistake: When the chef swipes the knife, he hits another alien in the chest cutting him vertically. The cut is obviously not that long or deep, however in the next shot the alien is slashed right across his chest very deeply. (00:58:50)
Visible crew/equipment: In a wide side shot of Derek driving the blue van thingy, you can see the front roof frame of the car reflected in the back window, which is driving along with it, filming this part of the film. (00:59:10)
Revealing mistake: Derek skids to a stop (on a road which is covered in gravel) - you can see a set of white tire tracks (kind of white skidmarks in the gravel, if you know what I mean) in the exact same place where he screeches to a stop. Multiple takes anyone? (00:59:15)
Visible crew/equipment: When the camera pans alongside the blue van, which is shaking, because Derek is spasming on the ground you can see some sort of dolly or camera with small wheels being pushed along. (01:01:10)
Continuity mistake: When Derek is lying on the ground by his car, his scarf is tied down to his crotch. When it cuts, it's tied down to his chest. (01:01:10)
Revealing mistake: When Derek is about to run over the alien with the machine gun, the alien drops the magazine from the machine gun. You can see he is lifting his little finger revealing that he intentionally drops the magazine. (01:02:30)
Visible crew/equipment: When Derek hits the alien with the blue van, splitting him in two, you can see the silver bar which the dummy is mounted on. (01:02:35)
Continuity mistake: When Derek hits the alien with his blue van, splitting him in two, you can clearly see that no blood gets on the windshield. Yet in a following closeup the windshield wipers are clearing a lot of blood from it. (01:02:40)
