Errores

Around 24:00 into the movie when the team is getting suited up, Emily is clearly seen sitting without her pants on. Then, 12 seconds later she stands up, fully clothed, and starts to take her pants off.

At 1:02:40, after Norah drops to the bottom alone then encounter a creature, she runs, stumbles and falls. As she begins to get up, her suit number 26, changes briefly to 8, then back to 26 in the same sequence.

Upon arriving at Shepherd station Norah can be seen placing an orange flare box on the table in front of her to examine its contents. Yet in the next shot both the flare box and previously moved equipment can be seen back in their original positions.

During the scene where Nora notices the station is leaking, she puts up her right hand to feel the water, the next scene switches to the side and it's her left hand that's up, then the scene switches to the front again where it's her right hand up.

At about 19:30 minutes into the film Kristen Stewarts character Roma arrives at the command center. She drinks from a bottle of water, but upon placing it down the lid is still on.

At 43:15, a group enters an airlock from the sea floor and the door control panel display is clearly shown. It rapidly counts up from 0 to 4.21 psi, then indicates that the airlock is pressurized. But at the drilling station's depth, at the bottom of the Mariana Trench, the water pressure is 15,750 psi. Also, the word "bar" appears just above the 4.21 number. A bar is a measure of atmospheric pressure: one bar is 14.5 psi, or roughly the Earth's atmospheric pressure at sea level. But, again, at the station's depth the water pressure would be 1,086 bars. Not 4.21 bars. And even if the air in the station is pure oxygen at the partial pressure of oxygen at sea level (as in manned space missions) the pressure should be 3.0 psi, not 4.21 psi.

The characters would not be able to talk to each other using radios underwater, voice transmission using radio is impossible Underwater. VLF radio can penetrate seawater to a few tens of meters but because of narrow bandwidth available the data needs to be compressed into code.

In the first few minutes of the movie, Norah finds a daddy long "legs spider in her sink. These spiders are predominantly found in woody environments. If in buildings or cabins, then they tend to be near to the chief food source. It is unfathomable [pun intended] that one would be would in a deep-sea drilling structure.

When Norah and her companions find the first dead body, the pupils of the actress contract as first Norah and then Rodrigo shed light on her. Given the fact she has been dead for at least half an hour, her pupils should be fully dilated, without reaction.

During the opening title sequence, a typo can be seen, twice, where a portion of the station's blueprints is labeled "BOYANCY COMPENASATORS"

When Norah, Emily and Smith arrive at the Roebuck Station, the on-screen title refers to it as a "Triton-Class Bore Site". A few minutes later, the voice of the automatic greeting system calls it "Titan-Class" instead, the same way it was defined by a similar system on the Kepler facility during the first act.

At 47:48 - When the captain said "They can't get through the tunnel", Norah said, "I'm the smallest, Let me check." Yes, she is the smallest, but all the suits should be the same standard size.

During the initial fleeing of the pressure breach, Rodrigo clearly states (@7:32): "We've got to seal the bulkhead." At (@8:02) he says: "The whole rig is about to implode. If you don't shut these doors it'll take the whole station with us."

However, a few minutes later, Rodrigo confusingly says: "You saved the entire rig. I... I didn't even know to close the door."
