Question: Mike and Sulley are able to activate the door when stuck at the kids camp by harnessing enough screams to activate it. If laughter is 10 times more powerful than screams, then why wouldn't child laughter (especially if there is a Birthday party, etc.) not activate doors from the "human world" allowing kids to go into the factory (monster world) all the time?
Answer: Well a door first needs to be activated from the monster side. See the doors of the human world lack the receiver for the energy they need to open the doorway between worlds (the red light on top). That's why in the monster world they hook a door up to a machine to activate it allowing the passage between worlds before any scream or laugh is made. It costs power to activate a door to allow a monster in. Boo was able to activate doors because she was in the monster world and her screams and laughs triggered the devices on top of the doors, activating them automatically. This was the first time ever a human entered the monster world.
Question: If Grug is so scared of things in the outside world and considers anything new to be dangerous, then why does he keep Guy with him instead of getting rid of him?
Question: Loki (as Odin) quotes a conversation that occurred between Thor and Odin. This conversation happened after Loki let go of the handle Thor offered to keep him from falling off the bi-frost. How does Loki know what Odin tells Thor when he's supposedly headed to Midgard (Earth) as they speak? Can Loki read minds? If so, I don't recall any movies he comes out in mentioning mind reading.
Answer: Loki has been shown to exhibit numerous powers in the movies that can explain how he knew about this conversation. In all the movies, he has been shown to appear in hologram-like forms in different locations. For example, in The Avengers, he uses this power to meet up with The Other who is in the middle of space, whilst he is on Earth. In the end credits scene for Thor, he was able to watch over Selvig and Nick Fury's conversation despite not being there. In Thor: Ragnarok, he was able to see into Valkyrie's past through touching her head (though this power was not established until Thor: Ragnarok). Any of these powers could have been used to find out about this conversation between Thor and Odin.
Question: How is it possible that picture 25 was in Walter's wallet the whole time, when the picture is of him later in the movie after he had received the wallet?
Answer: The picture was not taken afterwards - that spot is just a favorite Mitty likes to use to review pictures. That is why Sean O'Connell was quizzing Mitty's mum about his life/work habits, so he could take a picture of his friend for the last issue.
Question: Maybe this was explained in the film and I missed it, but it has been bugging me for a while. What happened to all the rest of the clones of Jack and Victoria after the Tet was destroyed? Presumably their daily instructions in the form of Sally would cease. Wouldn't they get suspicious? Some reasonable explanation would be nice.
Answer: They would obviously notice that the Tet was gone and would no doubt have questions, but, without outside intervention, would be unlikely to be able to do anything about it, as they would have no reason not to believe that the "radiation zones" confining them to their particular area weren't real. Some would likely die fighting Scavenger groups in their areas (without the drones, they'd be increasingly vulnerable), others might be successfully contacted by those groups and thus could join with them, some may have ultimately starved without resupply from the Tet. The film only covers what happens to Jacks 49 and 52; the others likely met with a variety of different fates.
Question: How could Superman kill Zod by breaking his neck? He's from Krypton like Superman so he should also be invulnerable.
Answer: Kryptonians aren't invulnerable. It just takes a lot to hurt one after he has been charged by our yellow sun. There are several beings who are strong enough to break a Kryptonian's bones. Doomsday, Darkseid, etc. Since both are roughly equal in strength on Earth, its no different than one human breaking another's neck.
Question: Why on earth does Bilbo remove the ring in front of Smaug? He has no real reason to believe that Smaug won't simply eat him or roast him. Smaug can hear and smell him but can't see him, so as long as he remains still, he is safe unless Smaug gets lucky. Seems like taking the ring off is a huge risk that was not necessary.
Chosen answer: Bilbo is actually quite clever, I think he was trying to talk his way out by buttering Smaug up. If he tried to run, Smaug, who was on high alert, would have caught him and swallowed him without a second thought. By playing with words he was able to both interest and distract Smaug, and get away.
Answer: Smaug started talking about the ring, which started drawing the attention of the Necromancer (Sauron), causing Bilbo pain. Remember, wearing the ring made one noticeable to dark forces.
Question: When Katniss asks Johanna about Annie why does Johanna kind of stutter when answering?
Answer: Joanna hesitates a bit when she's recalling how many years ago it was when Annie was in the games - she tells Katniss it was "four" then corrects herself and says "five." She then seems a bit somber when Katniss indicates that Annie had some kind of mental breakdown, implying that Annie is Joanna's friend. Joanna is being shown as having a softer side than the harder image she tries to project.
Answer: Joanna won her games the year after Annie. It's possible she stuttered and corrected herself when recalling how many years ago Annie won was because she was shocked by how long ago it seems her own games were.
Question: Spock stops a volcano from erupting by detonating a cold fusion device that causes ice to form over the volcano. I have problem with that because where would all the pressure inside the volcano go? All that pressure would have gone somewhere.
Answer: Unless the cold fusion went directly into the volcano, all the way to the source of the pressure.
Question: The alien predators are blind and hunt by pheromones. Why don't humans just wear hermetically sealed suits to block the pheromones, or use false pheromones as decoys?
Question: What I don't get is that if Thalia's tree had the barrier active all along while Luke, Annabeth, and Grover were kids, in the first film, how was the minotaur able to approach close to the entrance of the camp without being prevented?
Answer: Because the barrier prevents the monsters from entering the camp, not from getting close to it. It's the reason why after Percy used the fleece to strengthen the barrier, Luke and Kronos' army used the labyrinth to bypass it.
Question: Yukio said that it was always difficult for Mariko to make friends, but why?
Answer: It isn't really explained, however Mariko is distant and depressed. Presumably she has always been so.
Question: Did Woody really drive the truck his son traded in at the end of the movie, or was he dreaming?
Question: Something I've always wondered about trains in the old west on these unfinished railroads, and this movie brought it to my attention again. It shows the track still being built, and it's a single track for one train, no second track along side it. That being said, before the track was finished there is a train going down it one way at the beginning of the movie with passengers. When the train is taken over and forced to steam ahead out of control, it goes off the end of the track and crashes. Well if this hadn't happened, how would the train have gotten back? It is a one way train, on an incomplete track and stopping at a station to drop of passengers and supplies. How would the train have turned around to go the other way again?
Answer: There are stations in between the ends of the line that allow the train to unload passengers, unload cargo, hitch new cars, and turn to go in the opposite direction.
Question: Is Tony Stark related to Agent Carter ?
Chosen answer: No, they are not related. His father used to work with Agent Carter but that is as close as it gets.
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.
