Continuity mistake: When Barry is getting followed across the beach by the guy, Barry shoots him once and blood falls on to the floor, and also on to Barry's face. He shoots the guy a second time in the head, and the view is from behind as the guys head explodes. If you look at Barry during this shot, you'll see his face is clean of any blood once there, but then it returns in the next shot. (00:03:00)
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)
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)
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)
Continuity mistake: In the start of the film you see "the boys" driving in their car talking on a C.B. to another man in the group they are meeting. If you notice the one doing the talking spends most of the time with the CB backwards using the mounting notch by his face, but when the scene switches from inside the car to outside it is turned around the correct way. (00:08:40)
Continuity mistake: When blood is splattered on Derek´s glasses from the alien hanging in the rope, he turns away and in the next scene the blood is gone. (00:15:25)
Continuity mistake: When Derek shoots a hole through an alien, the alien falls over him almost going to the ground. When it cuts, the alien's head is side by side with Derek's head. (00:18:15)
Continuity mistake: The way that Derek's scarf is tied, and the position of it, and the way it hangs etc., changes between various shots throughout the movie. One good example is when he pulls the gun out of the stupid alien's body. (00:18:55)
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)

Continuity mistake: On the cliff, Robert jumps out and grabs Derek. Robert punching Derek square in the chest is shown between two different angled shots. In the first shot, as Robert pulls his clenched fist backwards, Derek's scarf has disappeared. (00:23:00)
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: 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: Robert drops a machete on the collectors lap when he has his hand trapped in the window, and the collector tosses it onto the passenger seat. in the following shot where he says "bye-bye," the machete is now repositioned. (00:29:25)
Continuity mistake: In the car on the collectors passenger seat there's a pile of collection bags, and a heavy machete resting atop. However in the shot where he pushes the handbrake down, you can see the passenger seat has nothing on it. (00:29:30 - 00:30:15)
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)
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)
Continuity mistake: When Robert manages to free himself from the collector's car, he keeps running after the car. He grabs the bumper which falls off. Robert falls to the ground beside the bumper. When it cuts, he has moved away from the bumper. (00:30:15)
Continuity mistake: When the collector gets hit in the head by the chef, he falls and slides down the stairs. He slides down about five steps, but when it cuts, it's only two steps. (00:32:40)
Continuity mistake: In the scene where the guys are getting the weapons from the car, in the forest clearing, the ground surrounding the parked car changes through the scene. At first, it is brown dirt with branches and twigs everywhere. By the end of the scene, when they exclaim "the bastards have landed," the ground is now covered with lush green grass. (00:39:05 - 00:40:55)
