From various dates, ages, and bits of information given, we know that, at least in the first episode, everyone (everyone being Clark, Chloe, Lana, Pete, etc) is 15 years old. Do the producers really expect us to believe that they're 15 years old? Clark's played by a 24 year old for one... [Yes. This practice is used all the time, and people are often surprised to find out that their favorite actors are older than they thought.]

In the Smallville T.V. Show, Clark knows he has a spaceship, however, in the old Superman Television show, "Lois And Clark: The Adventures Of Superman" Clark does not know that he had a spaceship and was shocked when he heard the news from his parents. [Any continuity errors between different shows shouldn't be regarded.]

In the episode entitled "Run, Season Four: Episode Five," Bart uses Kryptonite on Clark to make sure that he doesn't get followed. This would be impossible because earlier in the show Bart says that this is his very first trip to Smallville, therefore he shouldn't have known what Clark's weakness is. [Earlier in the episode, Bart stumbles upon a box containing the kryptonite in Clark's room. Bart opens it and notices Clark is weakening. When Bart asks him what's wrong, Clark tells him to close it because he's allergic to the rock.]

Jor-El's voice is provided by Terence Stamp, who played General Zod in "Superman II." [This is not interesting trivia by any stretch of the imagination, as Stamp's name appears in the credits and can easily be read. His appearance in Superman II is also well-known and does not need to be pointed out.] Corrected by Tailkinker

Kristen Kruek's last name is mis-spelled during the opening credits for every episode of the series. [Kristen Kreuk's last name is spelled Kreuk not Kruek.]

Chloe has been put in a coffin and buried underground. However the ground above her is covered in grass. Chloe was not buried for no more than even a day. There should not be grass over her grave, and there is no signs of it being freshly dug. [It is possible to pull up the grass and its roots with the topsoil and replace it after a hole has been dug. Usually its done to keep your yard from looking bad until new grass can grow. In this case it was done to hide the grave.] Corrected by Phixius

Clark takes Lana to the top of a windmill, and they can see Metropolis in the distance. Kansas is a completely landlocked state, and Metropolis is established as a coastal city. [No, in the Smallville universe, Metropolis is a city in Kansas that is roughly three hours drive from Smallville.]

When Clark realises Eric might have aweakness to Kryptonite he goes to get a meteor rock. His mum says "it's not like we have them lying around" so he goes to get the one off Lana's necklace. This would be fine except at the beginning of the episode and throughout most if not all the others it is well established that there are always meteor rocks lying around on the ground, in the water, in fact pretty much anywhere you look. [Kryptonite may be plentiful, but it is not exactly everywhere, especially not on the farm, and it usually only turns up when Clark and Co. don't want it to. Besides, at the time Clark couldn't find it easily because his powers were gone and the kryptonite wouldn't affect him, so it was just faster to get Lana's necklace.]

In this episode, as Clark and his parents are first discussing his new weaknesses, the school bus stops directly in front of his farm. In every other episode, Clark, Pete, and Chloe have to walk together quite a distance to reach the bus stop where they all get on. [Not true- in the pilot you can see the bus stop outside Clark's house, then drive off.]

Clark's x-ray vision reveals that the cemetery is rather oddly set up. There are a dozen headstones visible but only four buried coffins, and three of them don't line up with any headstone. Two of the coffins contain complete skeletons, but the other two are either empty or lead. While the occupants could have decomposed entirely, they are directly next to the younger corpses; usually cemeteries fill in one area and then proceed to another, segregating graves by age. [Cemetaries SELL plots a section at the time, but they don't fill them till the people that buy them actually get around to dying so you will frequently have series of graves belonging to the same family that only have one or two graves "occupied" but may have headstones (with no death date) for some or all of the empty ones.]

The Coach is setting all these fires off completely gutting various departments of the school. Does nobody investigate into these like police or fire accident investigators. When Clark gets his firing-heat-from-the-eye talent later on in season 2 the cops are all over him and those fires were relatively minor in comparison... [It's possible that the police did investigate the inexplicable fires the coach caused & couldn't find a reason, so they decided to keep a eye on the school for any other mysterious fires incase of acts of arson.]

At the beginning of the episode, Whitney says that Coach Walt's next game will be his two hundredth win. Later, while talking to the principal, Walt says that he has "been leading this team to victory for twenty-five years." Two hundred wins in twenty-five years is only eight wins per year, not really an impressive record. [Eight wins per year would be a winning season every year for 25 years since most high schools only play 10 to 12 games per year. I think that's impressive.]

In this episode, Clark's ship is completely different to the one shown in later episodes. [The ship is designed so that the outer part we see in the pilot protects Clark in space from assorted dangers, then falls away due to friction in Earth's atmosphere (this can be seen on the DVD opening titles before the menus) & leaves the sturdier inner part intact for crash landing.]

When the meteor shower occurs, Lionel is signing the contract to buy the factory. However, it comes up in a later episode that Luthorcorp is only able to buy the factory once Johnathan talks the owner into it, after Lionel got him and Martha adoption papers for Clark, which of course they didn't need until after the meteor shower. [Pete's family owned the creamed corn factory that Luthorcorp turned into the fertilizer plant. The farmer that he was signing a deal with that day may have owned other land in Smallville that Lionel was there to purchase.]

When Clark (again in his imagined football game) begins to run down field, he knocks 4 defensive players out of his way. These are numbers 82, 72,66, and 55. When he has run many yards, not only does 82 jump and miss him again (from the front) but he jumps over the same 4 players, in the same order they were lined up before, to land in the endzone. [It was a fantasy. He can imagine jumping the same players again if he wants to.]

Throughout Season 1 the ages/years in school of Clark, Lana, Pete, and Chloe are inconsistent. Supposedly they're all the same age and freshmen, as Pete states in the pilot episode the football team always chooses a freshman guy to be the Scarecrow, which would make them either 14 or 15. However, they're all seen driving (or refer to driving) at least once, which would make them 16, and Sophomores. [It is possible for some of them to be driving at age fifteen. Kansas allows fifteen year olds to have a Farm License, which allows them to use farm equipment and drive to and from school. There are some other possibilities as well, such as a Restricted License, read about them at Kansas' Department of Revenue website: http://www.ksrevenue.org/dmvteen.htm]

In the Pilot, Clark's spaceship has an almost shell-like appearance - it looks layered. Thereafter, it is smooth, almost shaped like a rounded arrow head. [The ship is designed so that the outer part we see in the pilot protects Clark in space from assorted dangers, then falls away due to friction in Earth's atmosphere (this can be seen on the DVD opening titles before the menus), which leaves the sturdier inner part intact for crash landing.]

No matter how strong Byron is, there is no way he could keep the helicopter down, unless he is very, very heavy. He would just pull himself towards the helicopter because there is nothing holding him to the ground. [It is an established superhero convention that characters with super strength possess a level of inertia proportional to their strength. It allows them to stay firmly planted while pushing or pulling.]

Chloe records Lionel's incriminating statement and then says to him, "I have your entire confession recorded on my voice mail, and the only person that has the password is me. So if I were you, I would reconsider my father's employment situation." But Chloe's statement doesn't quite make sense. If she's the only one who can access that voice mail, then the fastest way for Lionel to prevent it from getting out would not be to indulge her, but rather to kill her as soon as possible. Chloe would only gain control over Lionel with this information if she somehow had it rigged to automatically be released unless she input the password on a regular basis, or something like that. Even Lionel doesn't acknowledge the stupdity of her statement - he says that he doesn't respond to blackmail, and offers her a completely different deal. [Chloe's been doing the investigative reporting/snooping thing for a while now. It's very likely she's made preparations for if she were to disappear or die, like a sealed letter with her voice mail/computer passwords or people other than the authorities to come looking for her if she disappears. (As we see next season, when Lois does just that.)] Corrected by Captain Defenestrator

When Clark is about to put the needle in Chloe, he lifts his arm and brings it down hard. Clark has superhuman strength. He would have crushed Chloe's chest and smashed the concrete. [Clark is well aware of his strength, it is his oldest power and therefore the one he has most control over. Think of it this way...you can crush a paper cup easily, but every time you pick one up, you don't, because you don't try to. Clark can hold back with his powers when he needs to, so he could stab a needle into Chloe hard enough to puncture her sternum and enter her heart and not crush her chest doing it.]
