Continuity mistake: When Wanderer and Melanie first start to work together to escape, she walks out onto the balcony above a pool and places her hands on the railing, very close to one of the vertical dividers of the railing. The camera pans down to the pool then cuts back up to her. Suddenly, she is equal distance from the vertical dividers on her left and right, and the doors and windows she just walked through have disappeared behind her. (00:22:50)
Audio problem: When Tony is telling Pepper about what happened to Rhodey, there is one shot of the side of Tony, slightly to a back angle where he is talking. His jaw does not move at all while speaking during that shot. (00:27:10)
Factual error: They inject the infected Brunel with antibiotics to fight the bacteria, however there is no pulse and that means the antibiotic can never spread through the body, as there is no blood circulation.
Visible crew/equipment: In the opening close up shot of the eye, you can see a reflector screen reflected in it. (00:04:10)
Revealing mistake: When Tanya has just died, her face goes still and she stops breathing, but you can still see her pulse beating in her neck.
Factual error: In this relatively low-budget but extremely well-produced 2013 science fiction film, a 6-man crew travels from Earth to Europa (one of the moons of Jupiter) to search for traces of life in the vast oceans beneath Europa's icy surface. One of the astronauts dies in-transit, leaving 5 crewmembers to complete the mission. When the large "Europa One" interplanetary spacecraft arrives at its destination, all 5 surviving crewmembers descend in a small landing craft to the moon's surface, leaving the Europa One spacecraft in orbit, totally unmanned. This is an inconceivable factual blunder. The narration plainly states that this mission picked up where manned lunar missions of the 1970s left off; so, many of the same protocols are in place. Just so, no manned space mission would ever abandon the primary space vehicle in orbit, placing the mission at risk by sending the entire crew down together in a landing party. At least two astronauts should have remained aboard the orbiting Europa One just in case the landing mission went sideways (as it does in this film).
Revealing mistake: When the doctor intercoms the colonel because he cannot get into the medical room for the pregnant woman having nightmares, the camera shows the bridge intercom, which is simply the back end of a desktop computer with a couple of knobs stuck on it.
Other mistake: In final 14 minutes, the greys are attacking the house. Several screws are "unscrewed" from the plywood. The first two are turned the wrong way, and the sound effect is of tightening. (01:23:54)
Continuity mistake: The movie opens with a man walking with a dog by a body of water. He is holding the leash with his left hand and the dog is by his left side. Cut to the next shot taken from across the water, the leash is now in his right hand and the dog is on his right. (00:00:20)
Audio problem: On the oil rig at the start of the movie, the 2 actors monitoring the deep sea submarine's progress are subjected to a major explosion noise - yet they don't even notice it. Only when the 2nd explosion comes and rocks the whole rig do they react.
Continuity mistake: When Skippy is attacking Jason the blood on Jason's face moves around quite a bit. (00:23:24)
Revealing mistake: Not bad digital effects for a combination "Predator" and "Jurassic Park" monster movie, except that the dinosaurs don't cast shadows about half the time.
Visible crew/equipment: When the first car seen in the movie stops, the camera rig can be seen reflected in the hubcap.
Revealing mistake: After Alex shoots the intruder in the head, killing him, a couple of shots later you can see his chest slightly expanding and contracting, showing that the actor was still breathing.
Continuity mistake: When the awful cousin Charlotte hands Gwen the slice of unbirthday cake, she does it with her right hand, left hand, right hand. (00:04:20)
