Question: Why didn't Jarvis alert Tony immediately that Selvig was in his building assembling the machine on the balcony to open the portal?
Question: Why is Loki immune to death? He is repeatedly blasted, beat by Thor, and smashed by the Incredible Hulk.
Answer: While Loki is not immortal, he's just as powerful as Thor, and many mortals would consider him a God as well. Loki is actually a Frost Giant taken in by Odin, but is just an invulnerable to many attacks. There may also be an element of magic involved in his survival as well.
Question: After powering up Stark tower in New York, Tony and Pepper have a brief conversation about a "security snafu" in their elevator that she was responsible for in some way. What exactly would that security thing be?
Answer: It is mentioned during the conversation, that construction workers used Tony's personal elevator. Tony is using the term "Security Breach" as an exaggeration.
Question: Why does Captain America say that Fury has the same blood on his hands that Loki does? It seems unlikely that he is being literal to the point that the fact that Fury touched Coulson's dying body means that he has the same blood on his hands as Loki...What am I missing?
Answer: It means Fury is just as guilty for Coulson's death as Loki is.
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: Thor asks Loki who showed him the true power of the Tesseract. Then, he gets interrupted by Iron Man. But when Captain America asks Thor about Loki's plan, he knows exactly who is coming and why. Did we miss something? Did Thor already know? Or is he just guessing with a hundred percent accuracy?
Answer: Odin knew about the army. It is why he used the dark powers to send Thor to earth (a very difficult task according to mythology). Thor was probably referring to Thanos, although we don't find out about his role until the end of the movie.
Question: We all know that movie guns tend to have outrageous amounts of ammunition, but what about movie quivers? In the big battle Hawkeye is knocking out arrow-ey death all over the place, and most of the time his quiver seems to be full. Up until it's totally empty of course. So just how many arrows does that thing carry, and how many arrows did he shoot in the movie?
Answer: The arrows in Hawkeye's quiver are very tightly packed - promotional shots of scenes immediately prior to the final battle seem to suggest that he has several dozen arrows in there. The number does visibly decrease as the battle progresses, although the initial tight packing makes it less easy to tell. A number of the shots he takes are also at close range, allowing him to potentially retrieve the arrows for re-use - it's only once he's atop the building, mostly sniping at long range, that he finally runs out. As for precisely how many arrows he fires in the course of the movie, watch it and count 'em.
Question: **SPOILER** When Loki kills Agent Coulson, Coulson has his Captain America cards in his pocket but later Maria tells Fury something about the cards being in a locker. Did I understand that right? And how and why were the cards in Coulson's pocket?
Answer: Coulson never had the cards in his pocket. They were in fact in his locker all along. This was done by Fury to help motivate the remaining Avengers to work together and save the world!
Question: How exactly was Thor able to get back to Earth when the bifrost bridge was previously destroyed in his movie?
Answer: In the original "Thor" movie, Loki tells Thor that there are ways into Asgard other than the Bifrost. Then when Thor takes Loki from the transport and the two of them are alone, Loki says "How much dark energy did the Allfather have to use to conjure you here?". Odin used dark energy to open a wormhole to send Thor back to earth.
Question: Between the events in The Incredible Hulk (2008) and The Avengers how did Bruce Banner end up in India when he was last in Canada? Did it have anything to do with what happened at the end of the Incredible Hulk movie?
Answer: Very probably. The moving around is just how he lives: He goes to some remote area where he won't be recognized, but either the Hulk comes out or someone tracks him down and he has to move again.
Question: What is the thing in the background at 00:31:23? It looks like a tentacle or worm but I really don't know. I've scoured the internet looking for information but I can't find anything relating to the subject. It seems this hasn't been brought up anywhere. I'd greatly appreciate an answer. Thanks in advance.
Answer: It's a Leviathan, the same kind of "flying worm" seen later in the final battle.
Question: Loki gets captured at the opera. Thor then appears and captures him and flies him onto a mountain and is ambushed by Iron Man. At the end of their fight several minutes later, Loki is still there. This obviously means he wanted to be captured. Why would he want to have been captured? He already had the Tesseract, plus all the equipment he needed to open the portal and Hawkeye was just going to break him out anyway. What exactly was his objective once he was in the Helicarrier?
Answer: Loki wants to take out the Avengers as a threat, and the helicarrier is the best place to do that. In a deleted scene, Hawkeye and Loki are discussing this, and Hawkeye says that he knows they are on the Helicarrier, but it is impossible to find with a form of guidance. This you can see when Hawkeye is making his approach on the carrier: he was tracking Loki's scepter.
Question: Bruce Banner brings up at one point what SHIELD is doing in the energy business. That is actually a good question. If they want to use the Tesseract to build weapons, why would they spend millions of dollars and their top researchers on energy?
Answer: Because the Tesseract is a powerful energy source and only by understanding that energy can they hope to harness it to create the weapons that they need. And there are other applications other than weapons. For example, SHIELD's Helicarrier clearly requires an insane amount of power to keep running; mastering the Tesseract and the potentially unlimited power it provides could give them a whole new range of options there. Likewise their ground installations, vehicles, equipment, all of these need power too. There are plenty of good reasons why SHIELD would look into non-weapon-based uses for the Tesseract's energies.
Question: Loki is pacing in the prison on the helicarrier and just as he says "there aren't many people who can sneak up on me" Natasha is shown. In that shot half of her outfit is tan. at first i thought it was Loki's reflection in the glass but he isn't wearing anything tan. Can someone explain what's going on to me?
Answer: The cell has large glass windows connected by large white supports. It is one of these supports that you see dimly reflected against her black outfit which, along with the lighting, creates the effect that you describe.
Question: In the beginning of "Thor", the battle between Odin's army and Laufey's army happened in Norway. In (Captain America) the Tesseract was found in Norway during World War II. Do you think there is a connection ?
Answer: The Tesseract is described in Captain America as being "the jewel of Odin's treasure room", so clearly it has significant links to the Asgardians, making it perfectly reasonable that it was located in Norway. Whether its presence there is directly linked to the battle in some way is unknown.
Question: Was Natalie Portman ever approached to reprise her role as Jane Foster (from Thor) for this film?
Answer: As she was extremely pregnant at the time of shooting, which would have been impossible to hide, it's likely that her participation was never considered seriously. Given the desire to get the film out on their chosen release date, there would have been no question of delaying shooting to include her in what could only have been a minor supporting role at most.
Question: How did Thor know where Loki was after he was ejected from the Helicarrier?
Answer: Heimdall could definitely see where Loki is at any given time.
Question: When Loki first arrives and steals the tesseract, he looks sick or injured. The skin around his eyes is discolored, he seems to be in pain and/or have trouble walking (especially noticeable after Clint shoots Fury) and he needs help climbing into the back of the truck. Later in the movie, he's fine. What was wrong with him?
Answer: Without the stabilisation equipment that's built by Erik Selvig, the portal opened by the Tesseract is unstable (demonstrated when the residual energy from the portal completely levels the Project Pegasus installation). Passage through it can therefore be reasonably assumed to be a pretty rough trip, even for an Asgardian.
Question: Did S.H.I.E.L.D. originally consider Thor to be one of the Avengers before Loki's plans?
Answer: Probably. If you look at the map in the end of Iron Man 2, you can see all sorts of "superheroes" marked on it. New Mexico is also marked, where Thor would take place (in continuity) a few days after the events of Iron Man 2. Plus, when Fury was talking to the council, they also mentioned Thor and that he might be either an asset or an enemy.
