Continuity mistake: Eric is about to arrive to the place where his mum works, and there's a close-up of the cop's car chasing him. A big line of cars is seen behind him, but in the wide angle not only the cars are gone, but the real traffic is running in a perpendicular road to the one he's in.

Audio problem: Eric escapes from the cops in McDonald's and he says, "Well done, Mac" but his lips are saying something else.

Continuity mistake: In McDonald's, Eric holds Mac by the neck, in the next shot he holds him under the armpit, without having had time to make the movement.

Continuity mistake: When escaping from the cops, while holding onto the truck and zooming down the road, Mac is on Eric's lap, bare chested and with a couple of rags on his lap. Then Eric throws away the rags, but in the next shot Mac is covered in clothes that have appeared from nowhere.

Continuity mistake: When the neighbour and her mum are in the car waiting for Eric to come out of the house, one of the cops behind turns his head and stares at the car, but in the immediate wide angle his head is in a different position.

Plot hole: The Alien family finds itself surrounded by armed cops, scientists, and helicopters yet the next time we see them, some seconds later, is walking around some deserted area. If the Government set them free there's no point in the chase of Mac. On the other hand, if the family managed to escape, then the scene with them defenseless in the supermarket is absurd. No explanation whatsoever is given to this really important part of the movie.

Continuity mistake: Eric follows Mac's footsteps and opens the fridge. A bunch of glasses fall on him, none inside the fridge, but when he closes the door there's one in the fridge.

Plot hole: Mac tries to escape from the NASA premises reaching the closed electrified fence. In the next shot, couple seconds later, he has managed to appear on the other side, outside on the street.

Sacha ★

Continuity mistake: During the vacuum scene, the hose keeps swapping from being over Eric's shoulder to under his armpit. This takes place in really short time lapses.
