Corrected entry: The math sucks in a number of cases throughout the film. Worth (the designer of the cube) says the dimensions of the cube are 434 square feet (possibly meaning one side of the cube). That makes about 21 feet a side. So there would be exactly one room inside the cube since Leaven measures the room to be 14 feet wide. Still she figures out that there are 26x26x26 rooms. Also when Kazan is calculating the number of factors he tells a wrong answer more frequently than a right one. There are even even numbers he says are prime.
Correction: He doesn't say 434 square feet, he says 434 feet square i.e. 434 feet along each side. Allowing for the thickness of the walls of the individual cubes, this works out about right for a grid of 26 cubes on a side.
Corrected entry: The blonde doctor said that 'they' took away all her jewellery; her bracelet and all her rings. But when she hangs outside the cube with the rope-of-clothes, she grabs the hand of the black policeman and we can clearly see a ring on her hand.
Correction: No, she is not wearing a ring at all. I even slowed it down and there is no ring.
Corrected entry: When Leaven finds out that there are 26x26x26 rooms, it's because at a certain point she thinks there's a fault in the numbers. She says "it's impossible to have a number higher than 26". Now how can that be true when throughout the rest of the movie they struggle with big numbers?
Correction: Leaven is deriving the room numbers from the larger numbers that are inscribed in the cubes. It's the room number that cannot be more than 26 (other than the 'bridge' room), not the actual numbers that they're finding.
Corrected entry: With 17,576 rooms, it's nearly impossible to enter the same room twice while moving through the cube. Yet they find Rennes corpse, and end up in the room they started in. They were very lucky, or they knew where they were going.
Correction: It is possible to end up in the same room because the rooms move around within the cube.
Corrected entry: Spoiler! Leaven claims the "bridge" room is the room they started in and they should never have moved. This doesn't make sense, seeing as how they all started in different rooms. (01:19:15)
Corrected entry: When Holloway is hanging outside the Cube from the rope of clothes, it would seem that it disappears at the moment she falls. We see her climbing up toward Quentin, and the rope is around her waist. Then they're holding hands face-to-face, and in the next shot when she slips, the rope stays still. Then, as Quentin goes back inside, it's disappeared entirely, and he doesn't take it back in with him. (00:47:00)
Correction: The clothing rope is actually shown to fall down the hole with Holloway.
Corrected entry: Leaven holds her glasses in her hands whenever she is moving from room to room. But when they are holding the shirts they made into a rope, she has a glasses holder around her neck to hold them. If she had it, then why didn't she use it before?
Corrected entry: After you enter a new room, the chamber doors automatically spin their handles and close shut. There is a scene near the end where the cop closes a chamber door himself while another character is talking. The director admits in the commentary that this is because that particular shot was done earlier in the filming before he decided they would close automatically.
Corrected entry: About 33 minutes in Worth and Quentin have argument and Worth ends up screaming out "There is no way out of here". This leads to the revelation that he designed the shell around the cubes. Then when Leaven questions him he tells them about the door. Which means there is a way out that he knows of. So why did he scream that there wasn't?
Correction: While he knows that there is physically a way out, he also knows that the entire cube is essentially rigged to kill them, either directly or through their own actions. He simply doesn't believe that they have the remotest chance of getting to the exit, hence his statement.
Corrected entry: All the characters seem to have a purpose (math, leadership, escape artist, etc.) except for the character, Alderson(?), who dies in the very beginning. Why would those who run the cube bother to put someone who has either no skill or one we never came to know in a room where they would die immediately? The other characters seemed to have gotten a fair chance in that they didn't wake up in a booby trapped room. I don't believe even the cat burglar would have survived if he woke up in the same circumstances.
Correction: He was put in to die. By letting the others know how fatal the place could be, it would panic them even more, thus making it more fun and sadistic for the builders.
He was put in a white room like everyone else. He died in the room he went into not the room he started in. It was literally the only thing he did.
Corrected entry: It is assumed that everyone was in the cube for several hours. Quentin confirms this in the beginning by saying the guys have 5 o'clock shadow. However, at the end of the movie which occurs at least a day later, closeup shots of the men's faces show they are clean-shaven.
Correction: He only said that he, himself, had the growth. The other males' hair may not grow as fast.
Corrected entry: The Dice & Slice trap, which killed Alderson in the very beginning, would not work in reality. The grating has a rod below. Instead of dicing/slicing the victim, the grating's rod would bounce off his legs or feet.
Correction: I believe this is wrong. If you watch it again you will see that the rod is very low to the ground in comparison. If you watch, Alderson is knosked backwards slightly. This could be from the rod hitting his ankles, but the rest passing through and keeping him upright. It works in theory.
Corrected entry: Leaven says factorizing numbers to see if they're powers of a prime would be astronomical. Someone at the V.O.X. (CUBE message board of the official site) rightly mentioned that there are only 24 powers of a prime between 1 and 999, which are not prime numbers. Leaven is able to identify the latter and it would have been no real problem for the group to calculate the other 24 and remember them. It is not astronomical.
Correction: It may not be astronomical, but to Leaven it may seem to be at that point. As she says, she has been working for hours. She probably cannot think straight, and at the spur of the moment blurted it out. Don't forget that Quentin is always questioning Leaven and shouting at her, making it even harder for her to work. Another point is that Leaven is not supposed to work the powers out, beacuse this is the point when Kazan is introduced as a mathmatical genius.
Correction: If you listen closely, you can hear the door as Quentin enters - subtitles confirm it.
