Visible crew/equipment: When the guy falls off the cliff and splats on the rocks below, if you watch it in slow motion, you can just see an orange bucket appear for a few moments which chucks the blood in the air.

Continuity: 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.

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.

Continuity: 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.

Continuity: 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.

Continuity: 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.

Continuity: The slats in the rear window of Frank‘s car disappear and reappear.
