Question: If all of the base DNA for the dinosaurs in the park was obtained from dino-blood inside mosquitoes, where did they get the DNA for the Mosasaurus from? A flying blood-sucking insect would not come into contact with a sea dwelling dinosaur, and there are no amber-equivalents in the ocean to trap any sea based blood suckers.
Chosen answer: The scientific inaccuracy of the mosquitoes/DNA notwithstanding, at the end of the film the Mosasaurus surfaces at the edge of its pool in order to drag in the Indominus Rex. Assuming the Mosasaurus did the same thing to catch prey in its own time period, it's feasible a mosquito could have landed on its body and extracted some blood in that short amount of time, especially if the prey was putting up resistance.
And a mosquito would always be in that area and be keen on getting blood from that particular dinosaur? Plus, it didn't take much for the Indominus to be taken down since the Mosasaurus is kind of a big creature, so how hard would it be for other animals to be taken down as well? Added, the Mosasaurus was being fed a shark when we first meet it; it's not like it was hunting on its own in an enclosed area.
Mosquitoes are everywhere, so it's not a matter of convenience that one would be in the same area and being keen on going after that particular animal. Plus, I just pulled up the scene on YouTube and it takes close to 10 seconds for the Mosasaurus to drag the Indominous Rex to its doom, which is plenty of time for a mosquito to land on it and extract blood. And as I stated in the answer, the explanation of DNA being harvested from preserved mosquitoes is scientifically inaccurate anyway, so even a tenuous explanation of how a mosquito would get that animal's blood is no more tenuous than dinosaurs being brought back to life in the first place.

Question: Amy is almost drowned in the muddy water. After Russ saves her by artificial respiration, Nick asks him where he learnt artificial respiration. "French class." Russ answers. At the end of the movie, Nick at the table shouts, "I get it! French class!" So what does French Class mean?

Question: This has been a question that's always brought up. Was Ellie Grimbridge always a robot from the very beginning, or was she turned into (or exchanged with) one when she was held captive at the shamrock factory?
Chosen answer: She was turned into one when she was captured. The robots didn't speak and if you notice that after he finds her, she never says a word. As well, she displayed genuine emotion throughout the film before she was captured, something the robots also never did.
I agree, she was a real person until she was captured. If she were a robot, I think Chalice would have found that out when they made love. Plus, as you mention, she had real emotions until her robot replacement was rescued.
Answer: Another theory might be that Ellie has always been a robot but an advanced model that Cochrane designed to interact with the outside world.

Question: I remember seeing this movie multiple times years back, and i distinctly remember the restaurant being Taco Bell, why the sudden badly dubbed pizza hut in the new television version?
Answer: A number of the European releases of the film replaced Taco Bell with Pizza Hut, as Pizza Hut has a significant international presence, whereas Taco Bell is relatively unknown outside the US, with very few restaurants. While most versions around these days keep the US original dialogue, the altered versions do occasionally crop up, particularly on television.
Answer: In South Africa we also had a version that called the restaurant Burger King. I just always assumed that they changed the name when a franchise offered them more money for product placement.

Question: In the scene where Vincent is just about to launch, the doctor testing him mentions his son. My brother seems to think that the doctor knows Vincent is not who he pretends to be because he is Jerome Morrow's father. Is there any evidence for this?
Answer: None whatsoever. The doctor seems to have worked out that Vincent is not who he seems to be from simple observational evidence. It's because of his son that he feels sympathy for Vincent and hasn't revealed that he's tricking the system.

Question: In the openings scene, the prehuman drinks a tar-like fluid (like the one poisoning Halloway later on), while looking at a spaceship hovering above. He then dies, falls into the river and disintegrates. I do not understand this scene, is he the last of the surviving prehumans committing suicide and the ship above is the others leaving the planet?
Answer: The giant ship has landed on Earth to drop off the Engineer so that he can terraform the planet and make it sustainable for life. He might drinks the black stuff to break down his own structure and spread life on Earth through his own DNA.

Question: When Jackson and O'Neill send the nuclear bomb up to Ra's spaceship, why didn't he simply send it down again? Sure it wouldn't have made it back to ground before detonation, but at least his ship may have been spared.
Chosen answer: When Ra saw the bomb, he realised that it was a few seconds away from detonation. There wouldn't have been enough time to send it back.

Question: *Spoiler* What is the weapon that Sentinel Prime uses to kill Ironhide? It seems that all of the other Transformer weapons fire explosives or bullets, but his seemed to disintegrate Ironhide after he shot him.
Answer: the weapon is called an "Acid Rust Blaster" which seems to be similar to the cosmic rust seen in the animated series. the rust eats away at the Transformer's metal body.

Question: Why was Beethoven arrested? He wasn't doing anything illegal.
Answer: While it's not unusual for musicians to try out new instruments (playing a few rifts and even entire compositions) in a music shop, Beethoven's extended sampling-keyboard performance went wild, drawing an enthusiastic mall crowd into the relatively small music shop. The shop manager no doubt felt overwhelmed and called in mall security to clear out the shop before any damage and/or theft occurred. Keep in mind that the security team was already scrambling to respond to several simultaneous disturbances throughout the mall, all caused by 7 strangely-dressed oddballs (more than half of whom only spoke obsolete dialects and ancient languages). The time-travelers were, thus, probably all perceived as one group of pranksters or escapees from a mental institution.

Question: How come Harry and Peter stopped living together?
Answer: While it's never mentioned in the film, the most likely explanation is that Harry, as a rich kid, grew tired of "slumming it" and decided to move back into his mansion.

Question: O says that back in Cape Canaveral, in the unaltered time line, something happened to K that changed him. All that's really said though, is that he stopped and arrested Boris the Animal there. So what exactly was it that changed K?

Question: One of the early posters of this film shows a bearded guy (who is not in the film) coming through a wall crack and holding puppet strings with one hand. Who is this guy supposed to be and what does he represent?
Chosen answer: He does bear a striking resemblance to Stephen King. King was both the writer and director of this movie, and as such, was certainly the guy in charge of all the character's fates and pulling all the strings.
Answer: It is Stephen King.

Question: Whenever Tim goes back in time, his clothes change to whatever he was wearing at the time, but he always appears in the same spot that he left from. Both times he goes back to the NYE party he appears in the upstairs wardrobe. So what happened to the version of him that was already walking around at the party? Did that version of him just vanish?
Answer: This is one of the (many) time travel plot holes in the film, and unfortunately your question doesn't really have a definitive, or satisfying, answer. Richard Curtis has said he was less concerned with making an airtight time travel film than with the human story at its core, so he let things like this slide without explanation. However, since we don't see any "second" Tims around when he goes back in time, and no-one else seems to think of him as an "extra" Tim, we can safely assume that, yes, he replaces himself in the timeline when he travels back. (Of course, this doesn't explain what happens when he then returns FROM the past).

Question: Victor got his powers when his suit fused with him. Ben got his when he got pelted with rocks. Johnny was blasted with fire which explains his ability. But, how did Sue and Reed get their abilities?
Answer: It is believed that the heat from the radiation caused Reed to start "melting", which is how he got his rubber powers. It is unknown why Sue got invisibility.

Question: Why did Splinter make Michelangelo do flips after he jokingly said, "All the good ones end in O" to Keno?
Answer: He's punishing Michelangelo for disrupting the session with Keno, which he used as an opportunity to diss Raph.

Question: I'm aware that there is debate on whether or not Deckard was a replicant, but as I was watching the movie, I couldn't see any clues as to why anybody would think this. Did I miss something obvious? Why do people think this?
Answer: The two most notable hints are as follows. The first (which is only in the Director's Cut) is that after Deckard dreams of a unicorn, Graf makes an origami unicorn and leaves it at Deckard's apartment. Some people interpret this as suggesting that they're aware of the memories that have been given to Deckard to prevent him realising his true nature. The second hint is that replicant eyes glow in certain lights - at one point in the film, Deckard's eyes can be seen glowing in the same fashion. Ridley Scott has stated on several occasions that, as far as he's concerned, Deckard is a replicant, but he does concede that they deliberately left it as somewhat ambiguous - the viewer should decide for themselves.
Answer: In addition, if it counts, in the original version of the movie, Bryant says there were 'five skinjobs walking the streets'. Since Baty, Leon, Zhora and Pris only add up to four (and a subsequent scene confirms Bryant wasn't counting Rachel in his first statement), the fan theory that followed was Deckard was the fifth one. Obviously, this has since been rendered null and void as the more recent cuts of the film redub the line to 'four skinjobs'.
Answer: Rachel asks Decker at one point if he had ever taken the replicant test himself, and he doesn't answer. Even though the movie itself doesn't seem to stress the point, in the book on which the movie is based "Do androids Dream of Electric Sheep?", the question of whether the protagonist detective is an android is the main theme.

Question: How did Snake lose his eye?
Chosen answer: During a mission known as the "Leningrad Ruse." He and his flight squadron were sent unknowingly on a suicide mission. During it, his goggles cracked and let in a poisonous gas, paralyzing his iris. He has to wear the patch because his eye can't focus against bright light, causing pain. This is mentioned in the novelization.

Question: Why do they still have gravity when Romilly asks Cooper to turn of the spinning, when they neared the wormhole? The centrifugal force stops, but on the inside there is still gravity.
Chosen answer: They do not still have gravity. Romilly is actually floating, but nothing is ever shown from behind his back, so the floating is gone unnoticed. In fact, during some shots of Romilly, you can see his feet floating behind him.

Question: Why were the enforcers called sandmen?
Answer: In popular American lore, the Sandman is responsible for putting sand over your eyes to make you go to sleep. In this context the "sleep" is a euphemism for death, and the enforcers are responsible for making sure that everyone dies on time.
Answer: And what about just digging for bones for the Mosasaurus? I think this was said somewhere-although I can't remember where so apologies if I'm wrong-but I think Dr. Wu mentioned something about it, so I'm sure they could've gotten DNA WITHOUT getting the blood from a mosquito. It sounds possible in my opinion.
