Revealing mistake: The wires holding the small satellite the two alien men are 'channeling' across the lake are visible although it's supposed to be floating.
Continuity mistake: When Chris and Rudy arrive at the lake, it is sunset, but in the close-up of the lake and the sky behind, it is daylight.
Continuity mistake: When the alien scans the object from the lake, his thumb is right next to the lights on the remote. In the close-up, it's away from the lights. (00:27:48)
Continuity mistake: When the aliens retrieve the object from the lake and place it on the ground, it appears clean and shiny. In the next shot, its position has shifted; it's now suddenly covered in mud and sand, and the ground around it has been disturbed.
Other mistake: After the aliens fire, the soldiers drop instantly and the aliens walk toward them. Oddly, the next shot repeats the end of the previous one, showing the soldier's arm falling to the ground again. (00:26:35)
Character mistake: When the aliens fire and knock out the soldiers, the one on the left extends his right hand to ensure a safe fall despite being unconscious.
Continuity mistake: After the alien struggles with the dog and Jaime runs to grab the gun, its position changes between cuts, plus broken dishes appear next to the alien.
Revealing mistake: Jaime launches a trunk at the alien, who falls and breaks a beam. The pre-cut section of the beam is very obvious.
Revealing mistake: When Jaime breaks the table in two, the pre-cut section is visible.
Revealing mistake: When the dog jumps on the alien, the actor is replaced by an obvious stuntman (or animal trainer).
Continuity mistake: The alien leaves the remote on the side of the kitchen, but later it is seen stuck in the corner.
Continuity mistake: When Chris calls Jaime, her phone lies parallel to the paper beneath it. In the close-up, it is suddenly diagonal.
Continuity mistake: When the alien grabs the remote control to move the furniture, his hand is wrapped around it. In the next shot, his thumb is suddenly resting on top.
Continuity mistake: Max the dog lies unconscious on the rug. When the aliens move the rug toward the wall, Max is missing - only to suddenly reappear at their feet for no apparent reason.
Continuity mistake: The lettuce and the film it's wrapped in shatter when they hit the alien, but appear undamaged in the close-up.
Revealing mistake: When the alien blasts its gun and puts Max to sleep, it is the previous shot of Max waking up, just sped up in reverse. (00:33:25)
Revealing mistake: When Jaime karate-cuts the log in two, the pre-cut mark is visible.
Continuity mistake: The telephone cord changes position between shots. (00:19:54 - 00:28:28)
Continuity mistake: Before Aura disappears, Jaime's hair falls over her right arm. In the close-ups, however, it rests on her right shoulder. Also, a string from her poncho runs across her clavicle or not. (00:20:02)
Revealing mistake: When the spaceship arrives, it appears as a low-quality, pixelated composite image.
