Question: Anyone who has the Cube DVD, is it really true that if you put the DVD disc upside down in your player, that there is another film on it?
Chosen answer: Having just tried it with my copy (Region 1), no, it doesn't appear to be true.
Answer: I have heard that you can often have a short film by the same director on the other side of the DVD.
Simple way to tell is if there's printing on top. For a DVD to be double sided, both sides will have the same blank shiny surface. Any writing, like the name of the film, etc. will render the top level unreadable.
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.
Question: Is it revealed, in the Cube trilogy, the destiny to which Kazan is reserved when he walks into the bright light?
Answer: No, but given the nature of the organization behind the Cubes, it can be assumed he was either tracked down and executed or detained in order to place him back into that Cube or into another version.
Well due to his amazing luck and how most of the other people around treated him he may have been put back in The cube and this is not the first time he has escaped eventually they will get tired of him and leave he back on the streets alone covered in blood of his former friends.
Answer: In an alternate ending of the cube we discover that the cube was built on another planet so Kazan died.
Answer: If you watched Cube Zero, we see the same blinding white light when Owen makes it to the exit, but when he walks through it turns dark and he is chained up. He is then asked whether or not he believes in God. When he says "No," he is incinerated. Apparently, no one has ever said "Yes," so we don't know what happens if someone were to say "Yes." It is very likely that Kazan ended up in the same situation.
Answer: It's established that sound travels throughout the structure reasonably well. Also, they didn't travel relatively far, even with the rooms shifting.
Actually, considering the distance that they travelled and the injuries he sustained, Quentin would have had extreme difficulty catching up. It looks like the 3 travelled upwards at least 12 cubes, meaning Quentin would have had to climb up each one with the chance that any of the rooms could be trapped fast enough to catch up to them with enough strength left over to kill Leaven.
Adrenaline is an extremely driving force, so I'd still consider it entirely possible it happened that way.
