Continuity mistake: When the guys are in the forest clearing, getting guns from the car boot and changing their clothes, Frank says "Don't you forget Oz..." and he takes his white jacket off while he is speaking. But in the following shot Frank's jacket is now back on him again, zipped all the way up. (00:40:15)
Continuity mistake: When the guys are in the room eavesdropping on what the alien leader has to say, one alien holding a glass bowl walks in on them. In this shot, Frank's wolleen hat is off. Then in the shot when Frank punches the alien, it has reappeared back on his head. Cut back and it has gone again. (00:44:50)
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: 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)
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)

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)

Continuity mistake: When Frank nearly gets chopped by an axe-wielding alien, he grabs a knife lying near the chef (who is wearing a striped shirt) but when he finally gets the knife and swinging it upwards, the chef has now suddenly vanished. (01:05:45)
Continuity mistake: The slats in the rear window of Frank's car disappear and reappear. (01:07:40)
