* If E.T. is now Star Wars canon, why didn't he have some sort of blaster that he could use to pulverize his pursuers at the start of the movie, thus ending this thing before it could begin?
** Er, what? E.T. is Star Wars canon?
*** Technically, yes it is. George Lucas put an envoy of [[http://starwars.wikia.com/wiki/Asogian Asogians]] in the galactic senate in The Phantom Menace as a joke and a ShoutOut to his old mate Stephen Spielberg. As to why ET didn't have a blaster, his race is clearly quite peaceful and even if they did have blasters, a scientist collecting samples probably wouldn't know how to use one.
*** In [[http://www.goodreads.com/book/show/225698.E_T_The_Book_of_the_Green_Planet_A_Novel# E.T.: Book of the Green Planet]] you see that they really are a race of botanists, and ET is pretty young for his race and still lives with his parent.
** Better question: Since ''E.T.'' is ''Star Wars'' canon, what's Elliott doing with Star Wars action figures?
*** That is explainable with the LiteraryAgentHypothesis. The events of the Star Wars movies are supposed to be part of a record of events called Journal of the Whills. If we assume that, in the E.T. universe, the Journal of the Whills is real and George Lucas made Star Wars because he read it, the presence of Star Wars action figures makes perfect sense, as does E.T. seemingly recognizing Yoda.
** ET is Star Wars canon the same way humans are Star Wars canon.
** FridgeBrilliance: E.T. didn't know it was a kid in a costume and thought it was a legitimate alien. After the events of E.T. happened, the existence of alien life made news. Maybe George Lucas or someone from Lucas Film saw a picture of E.T. and used it as a background character. In their universe the appearance of the aliens is AluminumChristmasTrees.
* Since E.T. can make the bicycle fly at the end, why doesn't he use it to fly in the beginning of the film to avoid pursuit?
** Because he didn't ''have'' a bicycle at the beginning of the film.
** Maybe it takes concentration that is harder while running (not to mention the mindless fear). Sitting in a basket, on the other hand, doesn't tire one out nearly as much, and by then he was more used to the idea of being chased, leaving him with a clear enough mind to pull it off.
*** The novelization claims his growing telekinetic powers are a side-effect of the same process that is ''killing him.''
* Why in the cosmos did E.T.'s companions ''abandon'' him in the beginning? They appeared to be on a scientific expedition. Some local natives find them and start chasing. The rest of the expedition runs back to the ship, leaving one of their own behind. Wouldn't they have done a head count? Haven't they heard of the buddy system? And if they had no reason to wait five seconds for him to get back aboard, why did they come when he "phoned home"? Bunch of jerks.
** Robot Chicken covered this nicely. He's a retard and they ditched him on Earth b/c they hate him/they really are a bunch of jerks.
** Robot Chicken aside, your question assumes E.T.'s companions even ''care'' they left him behind. Aliens, after all, are aliens. That means an entirely different culture on top of an entirely different anatomy. Just because ''humans'' would be reluctant to leave one of their own behind doesn't mean aliens would feel the same ethical/moral obligation.
*** ET may have signed a release saying "if left behind you have X [ET planet] days to call us or you will be assumed dead or captured."
** We don't know if earth's scientists have a galactic reputation among aliens - maybe ''we're'' the ones doing the "probing".
*** Or maybe we have a reputation for violence. There's no guarantee that the approaching humans won't try to commandeer the spaceship, or start shooting at it and damage something. Maybe they've learned that it's better you leave one of your men behind then leave the highly advanced spaceship in the grubby hands of hairless apes.
** Eh. The whole "group panics and takes off, not realizing they left someone behind 'til later" is a fairly standard bit, really. Usually done with cars instead of space ships, though.
*** So E.T. is Home Alone 2 with aliens, and Elliot is the homeless pigeon lady?
*** Sadly, they cut the scene where they glued a ton of Reeses Pieces to the scientists and set the aliens on them.
*** This Troper had years of psychological trauma from this damn movie and would like to thank you for crafting a simple sentence that very nearly made him pass out in terror.
*** It would make sense for them to leave behind one to save the rest; maybe a little cold, but [[BlueAndOrangeMorality who are we to judge?]] Alternatively, they didn't want their technology to fall into human hands--a biological specimen is bad enough--and since humans were converging on their landing site, having their craft captured was a distinct possibility. After taking off, maybe they just took up a temporary position orbiting Mars or something in the hopes that E.T. would find a way to communicate; in fact, given that this is pretty much what I would do, I'm all but convinced that that's what Spielberg ''et al'' meant to imply. (Of course, this again runs into the BlueAndOrangeMorality issue again...)
*** That would make sense from their point of view. The humans were coming and they couldn't risk letting their ship get captured, so they had to leave without E.T. They then parked behind the moon or somewhere else in the solar system to try to figure out what to do now: even if they knew where he was, once E.T. joined up with Elliot, they couldn't risk exposing themselves by landing in the suburbs to pick him up, so it was up to E.T. to contact them and set up a new rendezvous point.
*** If E.T. is an average specimen of the species, it appears that they have VERY fragile psyches and are prone to panic at the slightest loud noise or any evidence of violence whatsoever. It's entirely possible that they all just panicked. It seems also like they waited for him as long as they could and then the humans got too close and then took off.
*** Imagine a group of scientists in the middle of the Amazonian forest with a helicopter taking botanic samples and then a very primitive and aggressive tribe attacks. They certainly will get away as fast as possible even if that means left one behind (though they may stay close to see if the lost scientist is able to send them smoke signs or something like that to show his position), now put that analogy but with aliens and humans.
* Obviously this would have made for a much shorter and less interesting movie, but a lot of problems could have been avoided if E.T. and the rest of his field trip companions had taken some sort of communication device with them when they left their ship ''to walk around alone on an alien planet''!
** Why would they need that ? They're telepaths.
*** So why does ET need to phone home, instead of just communicating telepathically?
*** Range. Can you yell loud enough for someone to hear you 30 miles away? It would be pushing it to assume telepathy works that far.
** I guess he didn't use a telepathic message to say, "Help, I'm being left behind..." while the ship was taking off, though.
*** Maybe he tried, and they heard and didn't want to risk coming back for him (see above).
** It's odd, but they're doing a survey on a primitive planet and trying to avoid contact with the locals. They might have deliberately left the ship with zero technology so that, if something went wrong, they wouldn't leave behind anything that humans could find and reverse engineer.
*** Then why couldn't they have done their survey somewhere that wasn't a short bike ride from suburbia? There are plenty of potential plant-collecting sites on the planet where there aren't any people for hundreds of miles.
*** Maybe the particular plant they're studying only grows in that area. There's nothing to say they haven't already been to all the remote locales and, for whatever reason, the one plant that can cure diseases, provide unlimited fuel or otherwise revolutionize their science just happens to be in a populated region.
* How do you threaten anyone with a Walkie-Talkie?
** Have you ever had a Walkie thrown at you? Those things hurt!
** A [[Franchise/TheHitchhikersGuideToTheGalaxy Vogon poet]] could be on the other end!
* Seriously, who has ever had to dissect a frog when they're in the fifth grade?
** Moreover, who has ever had to dissect a ''still-living frog'' in the fifth grade? The teacher even mentions that the kids will see the frogs' hearts beating when they cut them open!
*** My teacher tells me that schools really did do that in the past. Probably not in the fifth grade, though.
*** They didn't dissect them alive (quite), they dissected them brain-dead. The teacher would "pith" the specimens (= strike their heads to destroy the brain) before passing them out to the students.
*** No would the kids be responsible for euthanizing the frogs!
* What happened to the kids after E.T. left? They stole a government van, ran from the law, and disobeyed the feds. Did they get in any trouble at all?
** Maybe. They are children, after all, and the government knows that at least one was in some sort of psychic link with an extraterrestrial being, so they might assume that its influence was on all the kids. Whether that's a good thing or a bad thing depends on how much ''[[TheyWouldCutYouUp "research"]]'' they'd be willing to do to make sure. A hopeful sign: when they [[spoiler: [[ItWasHisSled believe ET is dead]]]], "Keys" is discussing what will happen to the family with Mary-mainly a rather short period of quarantine before they go on with their lives. A disturbing sign: the use of guns/walkietalkies during the chase. Take your pick.
* Why did ET and his ship land ''so close to human development''? California has national parks and things, too!
** Maybe they did it before. Many times, indeed. But this time, they wanted to inspect the flora in that specific area. One that just grew close to the Californians. Perhaps some kind of polluted plant that you cannot find in wild nature, or something like that.
*** Maybe THE ENTIRE experiment was bonding with a human. The "Phone Home" thing was just saying "Ok. Job's done, folks. Now pick me up"
** It's called "urban sprawl". The plants in question had been there for ages, but the suburbs have been spreading in recent decades. When the alien botanists noticed the area was being encroached upon by human settlements, they shifted that site from "Maybe we'll get around to it three or four years from now" to "Holy ***, we gotta sample that spot ''right now'' before somebody builds a shopping mall on it!". Hence, the haste with which they were searching the area, and the sloppy contingency-planning that led to E.T. being left behind when some humans showed up.
* Why are government agents driving around neighborhoods listening in on conversations? This is like some V for Vendetta level creepy.
** To hear if anyone was discussing the missing alien that they were searching for and was last known to be in the area-- and that's precisely what they found.
* So why exactly did the first government agents to arrive at the house wear space suits? It makes a sort of sense if they're going for protection from potentially hazardous alien substances, (since they don't know anything about E.T. or his biology and motives at the time) but that being the case, why not hazmat suits like Keys is shown wearing in the next scene when he first enters the house?
** This is just a guess, but space suits are designed to allow survivability in the harshest environment we've been to, other than the deep ocean. The first guys into the house had no idea what sort of crazy alien tech E.T. could have been packing. Best to wear the safest thing you can find until you verify there's no weird-ass radiation or toxins in the house.
* So why exactly did E.T. get sick anyway? And why did he suddenly get better?
** E.T.'s people are a race of empaths. The farther away from each other they are, the sicker they get, because their bonds are weakening. He'd been away from them for some time, and their apparently not receiving his "phone home" only made him reach the DespairEventHorizon that much faster. When they finally got his signal and responded, he was barely clinging to the last fibers of the last thread.
