Question: Robbie's soldier friend (I think his name was Nettle) was so calm and compassionate with him. He said that the hiding place was in reality the beach cottage and he protects Robbie from the angry soldiers. Did he do that because he saw how sick he is and probably knew, deep inside, that Robbie will not survive the night until the evacuation, and wanted to give him a peaceful end? Why does he take Robbie's letters and pictures with him?

Question: Why did Dunbar's superior kill himself as Dunbar was being taken to his new post?
Answer: He was mentally disturbed and was depressed about being assigned to a "dead end" post with no chance at advancement. Dunbar, the hero, choosing to be assigned to the frontier, just pushed the poor soul over the edge.
In a word, the disease syphilis. The urinary tract problems and the Insanity are possible side effects.
What are you basing this on? What in the movie indicates that he has syphilis?
Answer: Dunbar's superior supported the British ("The King is dead... Long live the King" said with a heavy British accent) and was likely a closet-case Redcoat his entire US military career. It was not rare and many suicides were a result of that.
This claim is not supported by the movie. "The King is dead. Long live the King" is a common idiom referring to the passing of power to someone new. It most definitely does not literally refer to the English King. The movie is set in the middle of Queen Victoria's reign. As for your assertion that there were a large number of English loyalists in the Union Army three generations after the Revolutionary War seems highly unlikely. Can you cite evidence of this?

Question: When Ben and the others enter the treasure room, who's carrying the Declaration of Independence?
Chosen answer: Abigail.

Question: If the witches were being hung outside the house when Winifred's book showed her how to cast the life spell, where did the black flame candle and its instructions come from?
Answer: They were set up, beforehand, just in case. Winnifred knew about the spell, but she didn't memorize the incantation. So she needed the book to see how to cast it.
If you pause the movie, you will see that the book opened up to the Black Flame Candle spell.

Question: Is "Googolplex" an actual word?
Chosen answer: Yes. A "googol" is the number 10 raised to the 100th power, or a 1 followed by 100 zeroes. A "googolplex" is an even larger number - 10 raised to the power of a "googol", or represented as 1 followed by a "googol" zeroes.

Question: Why and who were the guys following Rocky in the car when he was training?
Answer: They were Rocky's chaperones. They were even seen in the cabin Rocky was staying in and playing chess with Duke.
Chosen answer: People who worked for the Soviet government assigned to spy on Rocky.

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

Question: What type of guns did the time traveler use to kill the Confederate soldiers?
Answer: I'm pretty sure it was mp5 with muzzle brake.

Question: This is probably a stupid question, but I know nothing at all about how these kind of aircrafts are flown. What exactly is the purpose of the guy sitting in the back of the plane? All they seem to do in the film is look in all directions for enemy aircrafts.
Answer: These aircraft are extremely complex; the presence of the backseater, variously known officially as the Weapon Systems Operator or Radar Intercept Officer, allows the pilot to focus on the immediate needs of flying the plane, as his backseater can take on many of the other tasks required. They serve as navigators, tacticians, bombardiers, weapons systems operators and, of course, as we see in the film, an extra set of eyes; they use their discretion in passing information to the pilot, ensuring that the pilot has only data that's important to the situation and isn't swamped by trivia. Without the distraction of having to fly the plane, they can often be better placed to coordinate between multiple planes, leading to situations where the backseater can be placed in command of the mission.

Question: When shaving their chests by the end of the movie, Mills and Somerset are joking and then Mills gets serious, says "You know...?" and then stops. What do you think he was going to say? Maybe he was going to be nice to Somerset, but then refrained himself?
Answer: I've seen se7en hundreds of times, and I've always wondered what Mills was trying to say to Somerset, and here's my take. If you've noticed, the recurring theme between the two was their conflicting views on how they see the world around them. Somerset is the grizzled, experienced detective who has been through the ringer, so he's views are more pessimistic in nature. Which I can sympathize with. Mills being the rookie detective that he is, was the optimistic, "I'll be the hero" kind of guy. So much so that Somerset called him out for being too Naive, and that he can't be like that. So getting back to the question at hand. During the chest shaving scene, I believe Mills was about to tell Somerset that his dark pessimistic view of the world around them makes sense. Mills wanted to say that Somerset was right, which he wasn't able to bring himself to do.
Answer: I've always wondered this question as well. I think he was gonna say something along the line of "you know I haven't talked to my wife all day And that's very weird." Especially since Somerset just said be prepared for anything while transporting Doe. Speculation at best though.
When Mills and Somerset enter the station building just before John Doe gives himself up the female desk sergeant tells Mills his wife had phoned this puts Mills' wife into the mind of the viewer. When Mills says to Somerset during the chest shaving scene 'if I keep coming home late my wifes gonna think something up' is placing Traci again in the mind of the viewer. Then Mills says 'You know?' prompts the question what has happened to Traci.
Answer: Since he stands for wrath in the plot, in the said scene he was probably going to acknowledge his short-tempered nature. He doesn't and therefore he looses a chance of confession. What say?
Could be right. He certainly has explosive episodes of anger throughout the film. He may, just for an instant believe himself to be wrath. I think he ignores the thought because he is always optimistic, caring and believes in good. Therefore, due to these virtues he cannot be wrath. Somerset, the calmer, more laid back character is the pessimist who sees evil everywhere. One would think he would be angry at the world. Maybe he was like Mills when he was younger.

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: Shouldn't Bruce be as insane as Falcone? Unless the dosages delivered to Batman and Falcone, respectively, were different. Also, why didn't Rachel yell and scream and go crazy like Falcone did when he was hit?
Answer: Bruce is just as infected as Falcone, however he is rescued by Alfred shortly after he is poisoned and given an antidote by Lucius shortly after that. He is then bedridden for many hours. If he had not been saved as quickly as he was, he no doubt would have been a blubbering mass just like Falcone. The reason Rachel and even Bruce don't react the same as Falcone the moment they are poisoned comes down to how each individual person reacts to fear: Bruce tries to fight, Rachel faints, Falcone screams in horror.
Answer: Also he had taken it before, earlier in the mountains.
Question: How is Hulk a total mayhem on the aircraft carrier, almost killing Romanoff, but at the end he is acting as a team member? Banner did reveal his secret how to control not turning into Hulk, but not how to control Hulk himself...
Answer: During the end sequence of The Incredible Hulk Banner discovers that he can aim the Hulk in the right direction, give it a goal, which he uses to defeat the Abomination in that film. Key to that appears to be willingly accepting the transformation into the Hulk, which he does by choosing to jump from the helicopter. On the Helicarrier, Banner doesn't want to transform, it's caught him by surprise, he's fighting it, which is why it takes ages, is seemingly very painful and, as an involuntary change, the Hulk is out of control. In the final battle, Banner chooses to make the transformation, to "suit up", as it were, and thus the change is swift, painless and results in the cooperative Hulk capable of working with the others towards a goal.

Question: Does the photo at the end with Sy and the family actually happen or is this just Sy imagining what life could have been like with them?
Chosen answer: This is mentioned on the DVD commentary - it's deilberately open ended so one can interpret it as either it's Sy imagining what he wants to happen OR it's what really happened.
As Neil Jones said, the ending is open for interpretation. However, I think there is reason to believe that Sy imagined the photo. It shows him and the family outside of their house, all looking happy together. Would they want to take such a photo with Sy after the incident at the hotel? And before the incident, they were probably not close enough with Sy that he would be in a photo taken at their home. Him and no other guests/visitors.

Question: If the MAV could be blown over by a storm of sufficient force, wasn't it very risky dropping the Ares IV Mav five years in advance of the mission?
Answer: The crew (and mission control) are in constant contact with the previously dropped MAV and would have aborted the mission and continued back to Earth had the MAV become inoperable before their arrival. Weir states this explicitly early in the book.
Answer: Yes, it is very risky unless the new Ares MAV is in an area with much calmer weather patterns.

Question: Was Roman just playing dead in the coffin or was it a dummy? Hard to believe that he could be pretending because Gale checks his pulse.
Answer: No it was Roman. There is a technique you can do where if you apply pressure on the correct artery you can stop the pulse. EXTREMELY dangerous though.

Question: In the altered timeline, Flash initially could not travel through time because there was another speedster. How was he able to travel through time in the original timeline, when Zoom was alive there as well?
Answer: Flash couldn't travel through time later in the movie not because Zoom was alive but because Zoom was also tapping into the Speed Force, preventing Flash from gathering enough of the Speed Force to break the Time Barrier. When Flash originally went back in time it's likely because Zoom was in custody, therefore not tapping into the Speed Force at that time.
Answer: Batman kills Zoom so the Flash could use the speed force.

Question: What does Agamemnon yell right before the Greeks charge in the first battle?
Answer: He doesn't yell any words, just an expression of anguish over his brothers death.

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.
Answer: I think he realizes that Robbie most likely won't make it. He takes the letters so that he can get them back to his loved ones. He probably knows that there is a last goodbye to someone (his girl/his mother) in them. And, if nothing else, even if his body doesn't make it back to them, they have a piece of him to cherish.
