Continuity mistake: When Pacey drives Joey and Dawson to the market to get party supplies, they leave in broad daylight. It can't be more than a few minutes down the road, being such a small town. Yet as they drive there, the sun is suddenly going down, and when they arrive at the store it's dark and night time. It couldn't have gone from broad daylight to dark night time in that short period of time. It appears to be a very long drive, but it's just the local market.
Factual error: During the Pilot of Dawson's Creek, Joey mentions to Dawson that they are about to "Start High School" soon, implying they are just entering High School for the first time. When Jen shows up in the taxi for the first time, they also tell her they are Sophomores as well as she. I assumed this must be a High School that begins with Sophomore grade, meaning Middle School in their area must have been 6th or 7th through 9th grade. The entire first two Seasons of the show are their Sophomore Year. But in Season 3, during their Junior Year Jen meets Henry, a "Freshman". He is repeatedly referred to in the show as a Freshman, although technically Capeside High is supposed to be 10th through 12th grade. This makes no sense timewise, as there are no Freshmen at that school. The main characters all started High School as Sophomores. Also-there is a trivia section on one of the DVDs that lists certain classes/teachers the main characters had as Freshman English, etc. But since they had those classes/teachers in the show, they were really Sophomores which further verifies there are no Freshmen at the school.
Plot hole: When Pacey drives them all to the market, he explains that he had to 'steal' the car from his family, and thus doesn't have the keys. He makes Joey stay in the car while they are shopping, because he can't turn off the car. But later, at the end of the episode, Pacey suddenly goes running out of Dawson's house late at night, jumps into the same car and turns keys in the ignition to start it and drive off in a hurry. How would he suddenly have the keys to the car? He drove them all straight to Dawson's house from the market, with the crazy girl - and the car had been there ever since. He had no time to go back home to get the keys; and it isn't likely his father, the town sheriff, would allow his underage son without a legal driver's license, to have the keys.
Continuity mistake: When Joey and Dawson are in the rowboat after their dinner date, they are kissing and talking. Just before Joey says, "OK, that's enough, Jumbo," there is a shot of them from the rear and Joey has her left hand up around the back of Dawson's neck, scrunching his hair. The very next shot shows them from the front again, and suddenly both of Joey's hands are down nowhere near Dawson's neck. The transition was too fast for her to have moved her hand.
Continuity mistake: When Pacey is at Andie's house waiting for their date, he picks up a family photo of the entire McPhee family. There is a close-up of this photo, and you can see all family members including Andie's dead brother, Tim, and her father. Look closely at the man representing her father in the photo. It is not David Dukes, the actor who later plays her father. Apparently this scene was shot/photo made before David Dukes was available. (00:26:05)
Revealing mistake: When Abby and Jen are drinking on the dock, Abby suddenly falls into the ocean and drowns. Just as they show a close-up of Abby falling about to hit the water, you can tell it's a stunt person. Monica Keena is a fairly short actress, and the stunt person is noticably taller with longer legs. Also, Abby had been wearing a very decorated black and silver skirt while on the dock. But the person about to hit the water appears to be wearing dark clothing without any silver or glitter.
Plot hole: Jack and Jen go to Capefest, primarily because Jack wants to run into Ethan who invited him there for the festivities. Jack and Ethan spend time together at Capefest, and become friends. Ethan makes a comment that he wants to go straight to sleep because he is tired, and the next day was a big day, meaning 20 bands starting at dawn. But the next morning, before breakfast Ethan and Jack talk briefly, Ethan says 'Goodbye' and they go their separate ways without enjoying any of the music fun together. It doesn't seem plausible that Ethan would invite Jack to Capefest to enjoy the music scene, and then take off just when all the fun is starting on the main day. Why wouldn't they have spent the day together as friends enjoying all the bands and festivities which is what they went there for?
Continuity mistake: After Dawson and Eve check his locker to see if the PSAT test was returned, they then start talking in the hallway next to his locker. Just as Eve says "Tell me who you think it is", there is a shot of her from the rear as she turns around to face Dawson with her arms crossed in front of her, and down by her sides. The next shot of Eve is from the front, as she says "Whoever you were just thinking of"; and suddenly her arms are at an angle away from her sides with her hands on her hips. Then the next shot of Eve is from the rear, and again her arms are straight and back down close to her sides as she says "It is". Then the next shot of Eve, again from the front shows her arms back out at an angle again with her hands on her hips as she says "Simple and obvious". There was no time for her to have moved her arms and hands during this scene, the transition was too fast. Apparently the shots of Eve from the front, and from the rear during this scene were filmed at two different times.
Visible crew/equipment: When Joey is walking out to the pier to talk to Dawson, right after the wedding; the wind is blowing her dress back and you can see a prominent, solid line going up the front of her dress from about the waist up to the neck. I assume this is probably a microphone wire of some kind and not just a wrinkle, as the line is solid and protruding through the material.
Deliberate mistake: Throughout the first episode, Jen's bangs are long in scenes relating to her "Grams" and short in all other scenes. This is because the scenes involving her storyline with Grams was shot much later, after the show was picked up. (00:05:45 - 00:16:15)
Audio problem: At the end of the episode when Pacey and Joey are paying for their items, Pacey launches into a philosophical speech. The cashier has asked him whether 'they found everything they were looking for' and he answers no, but they found what they needed, which was even more important. He then elaborates, explaining that 'if you found everything you needed that day, what would be the point of doing it all over again the next day'. But Joshua Jackson apparently messed up his dialogue, because the point he was making was that they didn't find everything they were looking for, not what they needed. He was making the point that they did find everything they needed, so it would be contradictory to then explain that there was no point in finding everything you need. He meant to say 'if you found everything you wanted (versus needed), what would be the point of doing it all over again the next day'. Oops.
Continuity mistake: When Joey is talking to Eddie in her dorm room, she is facing him with her hands resting firmly on his shoulders. In one close-up of Joey, her hair is hanging in front of her right ear. In the next shot of her, the hair on her right side is suddenly tucked behind her ear. Her hands haven't moved, and no-one touched her hair. (00:23:35)
Plot hole: When Dawson runs into Grams at the Airport, she asks him to not mention her trip to Jen. But shortly after that in the same conversation, Dawson invites Grams to go say hello to Jen and Jack who are waiting for their flight. If Grams didn't want Jen to know about her trip, she couldn't very well just go meet Jen without explaining what she was up to. (00:20:40)
