Visible crew/equipment: When Derek plunges down the cliff, he lands on a rock, but if you watch carefully it's very apparent that two hands belonging to a crewmember throw a pair of fake legs over the rock. (00:23:25)
Continuity mistake: The water/rocks around Barry after killing the alien to when it cuts to Derek through his binoculars seem to change. (00:03:35)
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: 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: 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)
Visible crew/equipment: When Derek sits up after pushing the back of his head which had split open back up, crew is reflected in his glasses. (00:36:45)
Continuity mistake: The whole road and the roadside shrubs and bushes completely change between shots, after Robert pulls the bumper from the car off. (00:30:15)
Visible crew/equipment: In one shot where the camera is following alongside Robert with his hand stuck in the window, who is now running alongside the driving car, you can see, in the reflection of the collectors car windows, the top of the black car which is driving alongside, filming the shot. (00:29:50)
Continuity mistake: When the collector has got Robert's hand trapped in the window, he drives off, and his car's front license plate is missing, yet is back in the very next shot. (00:29:40)
Visible crew/equipment: When the Collector is in his car trying to get his window up, there is one shot of him outside of the car trying to get the window up. If you look in the reflection of his car you can see a camera being held. (00:29:00)
Continuity mistake: When we see Derek land on the rock after taking the fall down the cliff, behind the rock he landed on there is grassy hills and then some big rocks. Later when they say birds were the only thing he can relate to, it shows a shot of Derek covered in gulls, but now the huge rocks in the background scenery have gone, and in addition, the position of his legs have changed too. (00:23:25 - 00:25:55)
Continuity mistake: As he rolls down the cliff, one of Derek's shoe fall off, but they're both back on when we see him land on the rock. (00:23:20)
Continuity mistake: In close-ups, the gun that drops from Barry's pocket is sitting on a piece of wall plaster that fell off when he got attacked by the aliens in the shed. However the gun isn't there in any wide shots. (00:07:10)
Visible crew/equipment: When the collector is checking his map, you can see a crewmember reflected in the small window and the shiny sliver window edge. (00:05:55)
Continuity mistake: As Barry puts the body of the alien into the grass, his right shoe is clearly visible with no blood on it. In the next shot though, he says he should ring his strides out, we then see his right shoe covered in blood. (00:04:10)
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)
Revealing mistake: When Derek awakes on the rock, he obviously headbashes a gull made of wood. It is very fake, may be deliberate (This could be a "deliberate revealing."), but is a mistake nonetheless.
Continuity mistake: When Derek is holding onto the rope at the cliffs, we see the alien cut the rope. Later we see Derek holding onto the rope again. (00:21:30)
Audio problem: When Barry realizes he is out of bullets, he runs away. It cuts to the aliens running after him. You can see one of the aliens fire at him, but you can't hear any gunshot. (01:04:55)
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)
