When Constance kills the cheating man, Troy, she clearly splatters his blood all over the windows of the car. But later, when Sam and Dean meet the cops on the bridge as they look for clues in the same car, there are no bloodstains anywhere to be seen. The police even say it's "spotless."
In the first shot of the bridge when Sam and Dean go back to look for Constance, they are almost at one end of the bridge while the Impala is parked at the other end with the headlights on. A few seconds later, a shot shows the Impala in the background, but the headlights are off. Sam and Dean are also now a lot closer to the Impala, not to mention walking away from her, like they had just arrived.
Trivia: Sam's LSAT (Law School Admission Test) score was 174.
At 19:06 the background visible from both Sam and Dean's windows is that of flat land, as far as the eye could see. Yet a second later when they pull over, there is a large slope next to the road, that is thickly covered in trees.
At 31:17 the sheriff has both his hands on different sides of the box, as he talks to Dean. Yet when the shot changes, he is holding his hands together at the center of the box.
There is no "Jericho" city or town in California.
At the beginning, when Dean is walking out of the motel room, he puts the collar of his jacket up, then as the screen flicks between Dean and the officer he is talking to, his collar keeps going up and down many times.
After the scene where Sam and Dean are chased by the Impala and jump over the edge of the bridge, there is a brief shot that shows Dean wearing dry, mostly clean jeans even though his shirt and jacket are still wet and dirty.
During the 911 call, there should be a police officer watching Dean, not all the police officers need to attend the same emergency.
When Mary is on the ceiling, she is bleeding into Sam's crib, but when John is on the floor screaming, he is looking in a direction that indicates she is nowhere near the crib. Looking in that direction, there is no way Mary could have been over Sam's crib. Also, looking in that direction, there is no way John could have been looking at her if she was over the crib.
When Sam is telling Dean that he has to update his cassette-tape collection he shows one clearly labeled "Metallica," Dean takes it and starts listening to it. Rather than Metallica, we hear "Back in Black" by AC/DC. Originaly it was supposed to be "Enter Sandman" by Metallica, it was in the review copies sent out before the actual airing of the episode, then it was changed for some reason, probably copyright issues.
When Sam and Dean are talking to Amy and her friend, you can see that when the camera is facing Amy the cups of soda have ice in them but when the camera cuts to Sam and Dean the cups no longer have ice. It switches back and forth depending on who's facing the camera.
At the end of the episode when Jessica is on the ceiling on fire, Dean breaks down the door and drags Sam out. How did Dean know to come back? He had already driven away. (This is explained in the deleted scenes for the episode on the DVD release, you will see that Dean did in fact drive away, but looked at his watch and saw that it had stopped working at the time that he dropped Sam off, and turned around because he knew that Sam was in trouble.)
Trivia: The brothers drive a black 1967 Chevy Impala.
Where Sam lets go of the wheel when Constance starts driving him to the place she killed her kids, there is a shot of the steering wheel and you can see that the car is still in park even though it looks like it's moving.
Trivia: Dean's car's registration number is KAZ 2Y5.
In the show, Dean and Sam's mother dies on November 2, 1983, but on the pilot preview it says she dies on September 13 1985.
When the Woman in White gets into the first car you can't see her through the rear window of the car (but you can see the other guy), although her head is higher than the seat. If ghosts can't be seen through windows, then how come Dean saw her and managed to shoot her when she was trying to kill Sam?
Although Constance Welch leapt off the bridge on 4/25/1981, when Dean and Sam bring up a website with the information, the URL says "Archive/04-25-1971/", which is off by a decade.
For a trained marine, the co-ordinates that their father leaves Sam and Dean are pretty imprecise. 35 -111 are both in degrees and with no minutes and seconds to further qualify them. We're talking about an area of roughly 4000 square miles.
Jess: Sam! Get a move on, would ya? We were supposed to be there like 15 minutes ago. Sam! Ya comin' or what?
Sam: Do I have to?
Jess: Yes. It'll be fun. And where is your costume?
Sam: You know how I feel about Halloween.
Sam: I like your necklace.
Amy: Troy gave it to me. Mostly, to scare my parents with all that devil stuff.
Sam: Actually, it means just the opposite. A pentagram is protection against evil, really powerful. I mean, if you believe in that kind of thing.
Dean: Okay, thank you Unsolved Mysteries.
Dean: You can pretend all you want, Sammy. But sooner or later you're going to have to face up to who you really are.
Sam: And who is that?
Dean: One of us.
Dean: You're really serious about this, aren't you? You think you're just gonna become some lawyer, marry your girl..
Sam: Maybe. Why not?
Dean: Does Jessica know the truth about you? I mean, does she know about the things you've done?
Sam: No, and she's not ever going to know.
Dean: Well, that's healthy.
Dean: Whoa, easy, tiger.
Sam: Dean? (Dean chuckles) You scared the crap out of me.
Dean: That's because you're out of practice. (Sam pins Dean down) Or not. Get off of me.
Sam: What the hell are you doing here?
Dean: Well, I was looking for a beer.
Sam: Car all right?
Dean: Yeah, whatever she did to it, it seems all right now. That Constance chick--what a bitch!
Sheriff Pierce: So you want to give us your real name?
Dean: I told you, it's Nugent. Ted Nugent.
Sheriff Pierce: I'm not sure you realize just how much trouble you're in here.
Dean: You talkin' about misdemeanor kind of trouble or squeal like a pig trouble?
Sheriff Pierce: You got the faces of ten missing persons taped to your wall. Along with a whole lot of satanic mumbo-jumbo. Boy, you are officially a suspect.
Dean: That makes sense, because when the first one went missing in '82 I was three.
Deputy Jaffe: Who are you?
Dean: Federal Marshals.
Deputy Jaffe: You two a little young for Marshals, aren't you?
Dean: Thanks, that's awfully kind of you.
Sam: No. Whatever you wanna say you can say it in front of her.
Dean: Okay. Ummm, Dad hasn't been home in a few days.
Sam: So he's working overtime on a Miller Time shift. He'll stumble back in sooner or later.
Dean: Dad's on a hunting trip, and he hasn't been home in a few days.
Sam: Jess, excuse us. We have to go outside.
Sam: So what's the theory?
Deputy Jaffe: Honestly? We don't know. Serial murder, kidnapping ring...
Dean: Well, that is exactly the kinda crack police work I'd expect outta you guys...
Sam: So how'd you pay for that stuff? You and Dad still running credit card scams?
Dean: Yeah, well, hunting ain't exactly a pro-ball career. Besides, all we do is apply. It's not our fault they send us the cards.
Sam: I swear, man, you gotta update your cassette tape collection.
Sam: Well for one, they're cassette tapes. And two... Black Sabbath, Motorhead, Metallica. It's the greatest hits of mullet rock.
Dean: Well, house rules, Sammy, driver picks the music, shotgun shuts his cake hole.
Sam: You know, "Sammy" is a chubby 12-year-old. It's "Sam," okay?
Dean: Sorry, can't hear you. The music's too loud.
Dean: (nodding at two agents) No sir, we were just leaving. Agent Mulder, Agent Scully.
Dean: Nice work, Sammy.
Sam: (painful laughing) Yeah, wish I could say the same for you. What were you thinking shooting Casper in the face, you freak?
Dean: Hey, saved your ass! I'll tell you another thing. If you screwed up my car, I'll kill you.
Sam: Dad let you go on a hunting trip by yourself?
Dean: I'm 26, dude.
Dean: So, what are you gonna do? You just gonna live some normal, apple pie life? Is that it?
Sam: No, not normal. Safe.
(Jess walks in, wearing a Smurfs night shirt)
Sam: Dean, this is my girlfriend, Jessica.
Jess: Wait. Your brother, Dean?
Dean: I love the Smurfs. You know, I gotta tell you, you are completely out of my brother's league.
Jess: Just let me put something on.
Dean: No, no, no... I wouldn't dream of it. Seriously.
Sam: What the hell are you doing here?
Dean: Okay, all right. We gotta talk.
Sam: Um... the phone?
Dean: If I would have called, you would you have picked up?
Sam: Hey Dean. What I said earlier, about Mom and Dad, I'm sorry.
Dean: No chick flick moments.
Sam: All right... jerk.
Deputy Jaffe: So, fake U.S. Marshal. Fake credit cards. You got anything that's real?
Dean: My boobs.
Jess: Wait, you're taking off? Is this about your dad? Is he all right?
Sam: Yeah, you know, just a little family drama.
Jess: Your brother said he's on some kind of hunting trip?
Sam: Oh, yeah. He's just deer hunting up at the cabin. He's probably got Jim, Jack, and Jose along with him. I'm just going to go bring him back.
Sam: Yeah? When I told Dad I was scared of the thing in my closet he gave me a .45.
Dean: Well, what was he supposed to do?
Sam: I was nine years old. He was supposed to say "Don't be afraid of the dark."
Dean: "Don't be afraid of the dark?" What, are you kidding me? Of course you should be afraid of the dark. You know what's out there!
In the DVD commentary, creator Eric Kripke said that the show was pitched as Star Wars with Dean being Han Solo and Sam being Luke Skywalker.
Jensen Ackles cited this episode as his favorite in the premier issue of the Official Supernatural Magazine saying: "I mean, obviously the pilot stands out among all the rest."
Injoke: When Sam and Dean enter their father's motel room they see the same article about Constance Welch as they did before. When Dean asks if it says where she was buried the camera zooms in. In the article a neighbor says that Constance was a quiet but very lovely woman. This neighbor is named Deanna Kripke. Kripke is the maker of the show.
This episode was nominated for a Golden Reel Award for Best Sound Editing in Television Short Form - Sound Effects & Foley.
This episode was nominated for two Emmy Awards for Outstanding Music Composition for a Series (Original Dramatic Score) and Outstanding Sound Editing for a Series.
In the original script the reason Welch didn't want to go home was because she had killed her parents, not her kids. They decided to change it to her killing her kids so the character could be older and they could use an older actress. Eric talks about the change in the DVD commentary.

In-Joke: The name of the Woman in White, Constance Welch, refers to the actress Raquel Welch, who starred in the movie Myra Breckinridge. Breckenridge being the name of the road where Constance lived.
The original plan in shooting the bridge scene where the boys jump off, both Jensen and Jared were planned to go in the river. However, there was a costuming error and they only had enough for one of them to fall in... accidentally adding more humor to the episode.
Originally Jensen Ackles was called into casting to read for the part of Sam Winchester, then Jared came in and they liked him as Sam as well. That's when they offered Jensen the more devil-may-care and charming character of Dean.
The streets used are the names of streets from Eric Kripke's hometown of Toledo, Ohio.
They named one of the missing men after Scott Nifong, the show's property master.
When the pilot aired as a rerun, several scenes were cut, including at the end when Sam goes into his apartment to find that Jessica had made him cookies and left him a note saying "Missed you! Love you!" in front of the cookies.

Fans of Gilmore Girls might take a while to adjust to the characters' names. On Gilmore Girls, Jared Padalecki's character was named Dean, while on Supernatural his character is named Sam and his brother is named Dean. Fans of Gilmore Girls will also find it ironic that Jared Padalecki's girlfriend in this show goes by the name Jess. In Gilmore Girls, Jess was the guy who stole Dean's girlfriend Rory.
