Factual error: When D.J. is attacked by Dr. Weir, he is grabbed by the throat and is squeezed until his windpipe is broken, shown by the way he was breathing (or struggling to). When Weir seizes him again and throws him against a support beam, he screams in a way impossible for someone who just had his windpipe crushed.
Suggested correction: Dr. Weir doesn't crush DJ's throat at all. The noises he makes are simply choking noises because he is being picked up by his throat, there isn't even anything in the scene to imply his throat is being crushed, which in reality requires considerably more effort than most people believe.
Continuity mistake: In the last few scenes where Lt. Starck is getting ready to prep the Gravity Pouches, the tube in front of her fills with a bloody substance, then shatters, sweeping her away. She then falls down a hole in the floor where the ladder is. Later, when the tube is whole and the blood gone (showing that it was a last ditch scare attempt from the ship) she still has blood on her face. It couldn't be from the fall, either, because she landed on her back and wouldn't be bleeding from her hair line.
Suggested correction: The blood was real. That's why you see it on her face. It wasn't an illusion and the blood isn't gone, it just drained away through the grating.
Plot hole: An engineer on a rescue ship seems to be the first person instead of the entire planetary intelligence community and the NSA (as reported by Dr. Wier) to translate basic Latin from what the Event Horizon's captain said. Somehow nobody else with all the vast resources of the NSA and other government organizations could clean up the transmission to determine exactly what was said?
Suggested correction: The recording of the Event Horizon's captain was taken directly from the ship's log. It was only available to the crew of the rescue ship at that time.
No, the NSA and the military had that transmission themselves as it's Dr. Weir who plays it for the crew before they reach the Event Horizon. How would Weir have it if they didn't obtain the log until they got to the ship? The part that they had, and DJ heard incorrectly, was received by the government agency in charge, leading them to send the Clark into Neptune orbit for a search and rescue of the crew and the ship.
