Question: Question about the Director's Cut of the film. The scene where Brett is looking for Jones has been altered slightly - when he looks up at where the water is dripping from, you can actually see the Alien hanging motionlessly from one of the chains. Has Ridley Scott given an explanation as to why he added this new dynamic to the scene? It's easy enough to speculate why, but a link to an 'official' explanation would be appreciated.

Question: Why didn't Casey ring the police, after the call when she realied he was taunting and making threats?
Answer: Landline phones like the one used in the movie cannot dial out a phone number while the line is active. Considering the killer is continuously calling her, she can't dial out on the phone line. This is referenced in the movie itself when her parents arrive home, attempt to dial 911, and can't due to the line still being active.
Answer: Characters in horror movies are notorious for not doing the most obvious things. It's most likely that she was scared and not thinking straight at receiving numerous threatening phone calls, particularly when she is threatened after hanging up on the killer.
Also, when she told the caller that she was "two seconds away from calling the police", his response was that they'd never make it in time. She also knew he was nearby as he made comments that indicated he could see her. She didn't know it was someone that knew her. She's a teenager and scared, so her judgement was clouded. She reached a point where she believed her only chance was to get away from him by either fighting him or getting out and hiding somewhere outside.
Even in real life, people don't always think of something obvious when a situation is actually happening. I was a victim of armed robbery and almost died. No matter how much you read/hear about what to do in those situations, actually being in one is much different. It's easy for someone else to observe and say what a person should have done.

Question: How did Quentin find others in the last scene? he was left unconscious and he had no way to figure out where others went after that (considering his lack of knowledge in mathematics) so how could he possibly make his way to the bridge room?
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.

Question: When Evil is walking down the alley, why did Jerry chase after him? Evil didn't believe in the existence of vampires, so he wouldn't have been a threat to Jerry at all.
Answer: Peter's odd behavior at Jerry's house made Jerry suspicious. When he discovers the shard of the mirror on the ground he finds out why Peter was spooked: Jerry doesn't cast a reflection. Jerry then decided that Charley's friends must be dealt with. In Ed, Jerry sees something which would lead him to believe Ed would make a good servant. Jerry turns Ed into a vampire and sets him against Peter while he himself deals with Charley and Amy.

Question: Why does Miranda see a dead boy at the end? Her husband didn't "do" boys according to the Sherriff. Will she see every missing person now?
Answer: Probably, she has a sixth sense which will most likely help angry spirits bring down the person or persons who killed them or caused them to die.

Question: There are two scenes on the boat after they have seen the shark and Brody has a panicked look, while in the background a shooting star passes right behind him. This happens twice, but it's in the day time. Was it real?
Answer: Although the 1995 documentary "The Making of Jaws" claims that the shooting star was real, the fact is that the shooting-star background effect is a Steven Spielberg trademark in most of his films (first noticed in "Jaws," but also appearing in "Close Encounters," "E.T. The Extraterrestrial," "Indiana Jones and the Temple of Doom," "Saving Private Ryan" and others). Spielberg has always had a fascination with shooting stars, dating back to his childhood, and he works them into almost every film.

Question: How big is the Kothoga? In some scenes, the Kothoga is about the size of a tiger but in other scenes, it's almost the size of a horse. During the Kothoga's attack during the Supernatural exhibit, it is seen chasing a SWAT officer and it's very huge but in another scene, when it crashes through a skylight and lands in front of some computers, it's not very large.
Answer: While the size is never explicitly stated, the creature does seem to be somewhat larger than a tiger and approaching the size of a horse when the scene needs it to be. Perhaps its size changes as it eats and needs sustenance?

Question: How did the alien egg get on board the Sulaco? I thought it was by the Queen but she did not have that organ that she was connected to when we first see her and so she couldn't reproduce eggs.
Answer: Agreed the Queen could have stowed the eggs away on her body as Alien bodies, especially one her size, could easily have a couple of eggs hidden upon her, and we would not know. They are masters of disguise these creatures and can merge in with their own environments or others...what's to say an egg can't look like part of the Queen's body? In addition, could Facehuggers not attach themselves to the Queen's body and merge with it somehow? Flatten themselves against her skin maybe?
Answer: As we don't know the precise details of the Alien reproductive cycle, we don't know for a fact that the Queen would be unable to produce eggs without the sac seen in the film. The only other possibility is that somebody got the egg up there somehow. The only possible candidate would seem to be Bishop, who would have had to somehow have got the egg from somewhere, and flown it up to the Sulaco while Ripley was off rescuing Newt. There doesn't seem to have been time for this, so the only remaining option seems to be that they did indeed arrive with the Queen in some fashion, either laid while up there or, possibly more plausibly, rescued intact from the destruction caused by Ripley and carried somewhere on the Queen's body.

Question: On the plane, as Gerry is wrapping her stump and right after he admits he hadn't known cutting her hand off would work, Segen says something quietly, then adds "Now I'm just a liability." What does she say right before "Now I'm just a liability"? I can't hear what she says (it might not be English) and it's not in the closed captioning or in any transcript I've been able to find online.
Answer: Segen says in Hebrew, "עכשיו אני סתם עול" (phonetically pronounced, "achshav ani stam ohl"), which means "Now I'm just a burden." Then Segen says in English, "Now I'm just a liability."

Question: What kind of power did each of the four friends have? Pete can locate things, but what about the other besides reading people's minds?
Answer: Each of the 4 main characters; Jonsie, Pete, Beaver and Henry could communicate with one another telepathically. In addition to this power, Jonie also possessed a photographic memory. Pete could find or locate things. Henry could read other people's minds. Beaver had premonitions or some sort of sixth sense. He made a phonecall to Jonsie, knowing something was wrong and wrote ssdd on the phone booth.

Question: I know that the studio chose James Cameron to direct due to the strength of his script, but why wasn't Ridley Scott offered the chance to direct? And was the studio considering a sequel before Cameron joined?
Answer: It really was all down to James Cameron having already written the script and proving himself capable of directing with 'The Terminator.' It was just a quicker, easier, and almost certainly cheaper decision to let him direct his own script rather than get someone else, even Ridley Scott. While the producers had wanted to make an 'Alien' sequel almost immediately, at the time the head of 20th Century Fox didn't want to pursue it fearing it would be seen as an obvious cash-in and flop. When a new executive at the studio came in a couple years later, the project was put back on track, and I believe Cameron was the first to be approached to write the script.
Chosen answer: The studio was considering a sequel before Cameron was involved, but regarding directing it, Ridley Scott told "The Hollywood" in a 2008 interview, "They didn't ask me! To this day I have no idea why. It hurt my feelings, really, because I thought we did quite a good job on the first one." The studio liked Cameron's script and at that time he had enough clout to be able to insist on directing it.

Question: In the final shot, we see Jill's head move a little. Was that suppose to let the viewers know that she's alive or was it just a mistake?
Answer: I personally submitted this as a revealing mistake. There is no official statement from Wes Craven or anyone else involved in the making of the movie about it being deliberate. So in my eyes, it's a mistake.
Answer: I actually read that they noticed this before the movie came out and left it in to keep the ending ambiguous and since they were planning to make Scream 5, they felt that would possibly be the way to go.
That's very interesting, especially now that Scream 5 is finally getting made. Although it doesn't appear that Emma Roberts is returning.

Question: How is it that all the dead victims (except Adam and Lawrence) are found? What kind of clues could the police follow to find those secret locations and still don't have any about the jigsaw?
Answer: Perhaps someone in the vicinity smelled the bodies and called the police. Each of the victims shown on screen appears to have been dead for at least a few days.
Lawrence didn't also die, as he was shown to have survived in Saw 3D. I'm assuming you are talking about Zep.

Question: What exactly is the experiment all about?
Answer: To test the bond between children and their parents.

Question: At the end we discover the kid survived unscathed in the explosion, which makes one believe Ginny survived too. So what happened to her? Did the kid murder her?
Chosen answer: If we say Ginny did not survive, we assume two scenarios: 1.) Each key represents the personality that was killed off in Malcolm's psyche. So, all in all 10 personalities have died. 2.) Ginny was the sixth one to be killed. This means that she has key #5 with her - remember that we are counting the killings in descending order. However, it was not shown anywhere in the movie how Ginny was killed by Timmy. So, it can also be said that aside from Timmy (who was seen walking away from the car explosion), Ginny (whose body was never found after the explosion) also remained alive. Ginny's state is inconclusive.
No she does die. At the end of the movie they show her being suffocated by Timmy.
Nope, that's Timmy's mother that's being suffocated.
No. Timmy suffocated his mother in the bed.
That was his mother, not Ginny.
Answer: Since Timmy is the killer here, it would be correct to assume that he blew up the car and took Ginny away during the commotion and killed her in some way that isn't shown in film. Or else blowing up of the car becomes completely pointless and a classic like this won't show a scene that doesn't have a significance. So blowing up the car was actually a part of the plot to kill Ginny.

Question: Is there a reason why when they're in the past they can't catch up with the present, but when they land a little into the future, the present can catch up with them? Are they not moving along on their own timeline? And if not, why are they not left in that moment and stand there to see the present come and go without taking them?
Answer: Think of time as a gear with only one tooth, and think of them as a gear with only one notch. In the past, the one tooth has forever passed their notch and they'll never be carried along in the flow of time again. In the future, the tooth comes along, snags their notch, and they're back in the flow of time.

Question: Who did the demonic voice that told the priest blessing the house to get out?
Answer: George Lutz.
How was it accomplished?

Question: Maybe I missed something, but how was Esther able to fool everyone practically all her life and hide the fact that she's a 33-year old sociopath? When Kate finally learns the truth by getting the phone call, they show a photo of the "real" Esther, so at least those records of her exist somewhere. How could the boarding school not have known her true identity?
Answer: The boarding school was going by the falsified records that Esther had with her. They did not suspect anything, so they had no reason to dig any further at the time.
Answer: High quality makeup was an important part of her disguise as the alternative ending make apparent. Her fake freckles were the master's touch.
Answer: According to the commentary on the DVD, Ridley didn't add this scene to the original cinematic release because he thought it revealed the true horror of the Alien too soon in the film. The scene is quite early in the film and he thought revealing the fully matured Alien at that time would reduce the viewer's fear.
I had watched Alien several times before I noticed the Alien hanging there.At this point the Audience have no idea what the Alien looks like, they're looking at pieces of science fiction equipment put in by the production crew that they can't relate to, so for all they know the Alien could just be a piece of kit hanging there.
