Question: Who is the vendor or manufacturer of that pull-up bar stand that Tony Stark is using near the beginning of the movie? And where could I get one?

Question: What exactly was the role of Martina in the movie? Was she spying on Hulk in any way, as she lived in the same building as Banner as shown while he was being chased by Blonsky? Or was Banner in love with her while he was in Brazil?
Chosen answer: Neither. Martina was simply a woman who happened to live in the same building and work in the same factory as Bruce. She was however attracted to him.

Question: Why are Justin Hammer's hands dirty when he is sitting with Vanko in the hangar, after he busted him out of prison?
Chosen answer: It is stated in the commentary that Sam Rockwell wanted his character to have a spray tan, making his hands an orange color.
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: Since Loki is the son of Laufey the Frost Giant, why doesn't he look like one?
Answer: When initially found by Odin, he does. Something then acts on him that causes him to mimic Odin's more human appearance, which he then keeps until his exposure to the frost giants during the events of the film, which tips him off to his true nature. Whether this was caused by some magic inherent in Loki even as a baby or whether Odin did something to disguise the child's true origin is unrevealed.

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: When Scarlet Witch attempts to mind control Hawkeye, he turns it back on her and says something like "Already done the mind control thing...didn't enjoy it the first time." Was this supposed to be an in-joke reference to the fact that Jeremy Renner was publicly bitter about having to spend most of the first film being mind controlled by Loki (which almost got him fired)?
Answer: It's not an in-joke about real life. It's just a direct reference to Loki mind controlling him.

Question: After Toomes says to Peter "Really? Stark?" Did Liz say "so cool"?
Answer: Yes, we hear Liz say, "So cool" but since she's sitting behind Adrian we don't actually see her saying it.

Question: How does Cap know that Bucky killed Tony's parents?
Answer: In Captain America Winter Soldier, when Cap and Widow are in the military bunker that has the mind of Zola in it, some images flash across the screen that Cap can see. One of them actually shows links to Winter Soldier and Tony's parents. It's not concrete, but not too difficult to put together for Cap and he deduces things on his own. As well as his time talking with Bucky who does claim to remember them all.

Question: Why doesn't JJJ look like himself? True he's being played by JK Simmons but here he's bald without the trademark Jameson hairstyle.
Answer: The general movie-going audience doesn't always know the difference between MCU movies and movies that are based on Marvel properties made by other studios. Jameson's different look might have been done to avoid confusing fans into thinking that this iteration of Spider-Man is somehow connected to the Sam Raimi films.

Question: Pierce asked Cap if Fury told Cap that Fury was the one who bugged it, but what did Fury bug?
Chosen answer: They were talking about the apartment Steve Rogers lives in. Pierce is saying Nick Fury bugged Cap's apartment, one of his own agents.

Question: Given there's only a few months between this movie and the previous one, that means it's set around 2014 vs. Infinity War being set in 2018, as best anyone can figure. Is there any official word on what the Guardians are up to in the intervening 4 years?
Chosen answer: Short answer: Probably nothing much good. In all that time Quinn still felt like a reaver, and Rocket doesn't deny he likes crime. Only Gamora keeps them at bay from doing anything really nasty. In the mean time they try to do good things, protect planets, hunt pirates, stuff like that. It's a crazy bunch of individuals.
Answer: They're mercenaries, like we see with the Sovereign. They do good things for money. We see this with the Sovereign, and Quill's comments make this seem like this is normal. Later, Rocket makes a comment about raising their prices. In Infinity War, they only respond to the Asgardian distress call because they expect to be paid.

Question: Before he was genetically altered and his real body was used, how did they get Chris Evans to look so scrawny?
Chosen answer: A couple of techniques were used. In most cases, Evans would film the scene normally, then the effects team would digitally shrink his character down to the smaller size. This would generally require some on-set adjustment to allow for eyelines - in some cases Evans would be physically lower than other actors, in others, they would look at his upper chest while he looked over their heads. In a few cases, actor Leander Deeny, who possessed the necessary scrawny physique, would film the scene, collaborating closely with Evans to ensure that the character's mannerisms remained the same. Deeny's features would then be digitally replaced with those of Chris Evans. Deeny appears briefly in the movie as the bartender in the pub Rogers visits to recruit his team.

Question: Is the movie supposed to have any connection with the Avengers? Is Xandar one of the nine realms? Does the orb have anything to do with the power of the Tesseract?
Chosen answer: Each realm is actually more of a dimension than a single world. So Xandar would be part of Midgard. The orb is the housing for one of the Infinity Gems. The Tesseract is also an Infinity Gem. The stone in Loki's scepter and the Aether from Thor: The Dark world are two others. All 6 gems can be combined on the Infinity Gauntlet which enables the user to do whatever he wishes just by thinking about it. Wielded by Thanos, among others, in the comics.

Question: What happened to Loki? Does this mean he's now alive?
Answer: The Loki from the original timeline is dead, but the 2013 Loki that is imprisoned on Asgard is presumably alive and well, and the 2012 Loki that escaped with the Tesseract is alive and supposedly, this version of the character will be the focus of his own upcoming Disney+ series.
Answer: The Loki who escaped is in a different timeline, so he will not encounter the "main" versions of the characters. This version of Loki will appear in the new series.

Question: When Dr. Strange gets into the accident near the beginning of the film, why didn't his car's airbag deploy? Wouldn't such an expensive car have all kinds of standard safety features?
Chosen answer: The airbag did deploy. However, the deployment occurred when the car first crashed and we see the accident from the outside, so we can't see it. Once we get a shot of the interior, you can see the airbag is sticking out from the steering wheel, but (unlike what some movies would show you) airbags deflate very rapidly after a crash, so you may have missed it.
But if the airbags did deploy, then why did he have such major injuries? Wouldn't the airbags have made what happened to his hands less severe?
I don't think so. I watched it again recently and I think I saw the car's speedometer crush his hands while they were still on the steering wheel, while the airbag deploys from the centre of the steering wheel, nowhere near his hands.
Often in real life, when air bags deploy from the steering wheel, they force the hands off the steering wheel resulting in the hands hitting the windshield. Damage to hands, wrists, and lower arms are common.

Question: As Kurt is loading the hack to deactivate the laser grid, Paxton and his partner are banging on the van, demanding that Kurt and Dave come out. Just as the program finishes loading, the cops open the door and drag them out. If the van was locked, how did they open the door? If It wasn't locked, why did it take so long to just open the door?
Chosen answer: They could have opened it with a crowbar or a Jaws of Life. (Likely the crowbar, since we didn't hear metal rending).

Question: If, as Odin says, Mjolnir was never the source of Thor's power, then how come that "Whosoever holds this hammer, if he be worthy, shall possess the power of Thor"?
Answer: If other people are worthy, they can gain the power of Thor (this is something that has happened in the comics), but Thor can muster that power alone. In his case, the hammer simply allows him to focus his powers.
How come then that in the first movie when Odin wants to remove Thor's power he "confiscates" Mjolnir? If Thor's power is intrinsically inside him, how could Odin remove it? Then, he reacquire those powers only after holding Mjolnir again, which implies Thor's powers come from Mjolnir. This is poorly explained in the movies.
"Poorly explained" doesn't make it a mistake. Odin suppressed Thor's innate powers and removed the hammer both symbolically and to prevent Thor from using it to reacquire his powers.
Answer: An independent guy from the UK called Ian. He's made over 3000 of his product and creation "hot gym".
