Continuity mistake: When Joey and Pacey are sitting on the bed talking during the party, there is a shot where Joey is looking to her right, directly at Pacey. The next shot of her, she is suddenly looking down and completely away from Pacey. The transition is too fast to be realistic. (00:16:55)
Continuity mistake: Right before the graduation service, Dawson is joking with Joey to get her mind off her speech. The wind has blown Joey's tassle so it's caught partly on her left ear facing the camera. But in the next shot of her, the tassle is suddenly hanging normally in front of her ear. She hadn't appeared to move her hands.
Continuity mistake: When Joey and Pacey are talking at the table on the Promboat after the 'brutal breakup'; her arms keep changing position too quickly between shots. As Joey says, "You break my heart into a thousand pieces," her right arm is folded across her, and the right hand is resting on her left sleeve just below the bare shoulder. The next shot, from behind Joey you can see her right hand still gripping her left shoulder, but the sleeve is further up and ruffled on that side. Then just before she says "Just leave me alone", the next shot again shows Joey from the front; and suddenly her left arm is raised up, hand by her face, and the right arm is down on the table with the hand curved up in the air. As she says "Just leave me alone"; her left arm is still up and hand resting by her face, and the right arm is laid sideways across her, hand on elbow. Then the next shot of Joey shows that suddenly her pose has changed; and her left arm is raised up diagonally, hand across her right shoulder, and her right arm is still laid horizontally across her, hand by her elbow. All of these transitions are far too abrupt and fast to be realistic.
All Good Things... (1) - S6-E23
Continuity mistake: When Joey is kissing Chris at the start, at first her hand is down, resting on the cushion. When the shot changes (right before she asks 'I don't really sound like her, do I?') her hand is up on the back of his neck. (00:03:05)
Love Bites - S6-E18
Continuity mistake: When Jen is talking to Grams and pours herself a glass of juice the fridge behind her is open. The camera cuts to Grams for a few seconds and when it cuts back the fridge is closed and the jug of juice has disappeared. While the camera does go off Jen for a few seconds, it was nowhere near long enough to put the juice back in the fridge and close it, then run back to where she was standing. Plus, there's no sound of the fridge door closing.
Continuity mistake: In the intro to this episode, the camera is panning the family photos of Dawson and his family. There is a close-up of a photo of Dawson and his parents, and Gail has the really long 'big' hair she only wore in Season 1. At this time, Dawson looked much younger and had longish hair himself. But in the photo-Dawson has much shorter hair and looks older as in current time. Apparently the photos were put together just for this episode.
Continuity mistake: When Joey comes out of the changing rooms, her left dress strap is slipping off her shoulder in the shots from behind, but sits correctly on her shoulder when viewed from in front.
Joey Potter and the Capeside Redemption - S6-E22
Continuity mistake: At the end of the day, Joey and Dawson are laying on his bed talking. When Joey asks Dawson how he would describe his film, there is a close-up of Joey looking directly at Dawson, who is to her left. The next shot, as Dawson answers, Joey is suddenly staring straight up and not looking at Dawson. Then in the next shot, Joey is again looking back at Dawson to her left. The transitions are too fast for her to have actually moved her head. (00:34:10)
The Kids Are Alright (1) - S6-E1
Continuity mistake: During the beginning intro monologue, Jen is shown seated between her parents on a couch. The two actors portraying her parents are only shown from the back, but they appear to be different people than the original actors who portrayed them. The father, especially has different hair and wears glasses. (00:01:40)
Continuity mistake: During this scene towards the end, Bessie insists on putting lipstick on Joey for Graduation. She dabs it on quickly, and there appears to be a noticeable smudge or mark on Joey's upper right lip from the lipstick. But the next shot of Joey, the lipstick suddenly appears normal and perfectly applied, and the smudge is gone. (00:33:40)
Continuity mistake: When Aunt Gwen is talking to Dawson and Joey in the store, just after she says, "General all around cuddliness between the two of you"; Joey is facing her and Dawson is turned the other way, with his back to her. But the next shot of Dawson is a close-up, and he is suddenly facing Aunt Gwen as he says, "OK, I'll tell you the long soap opera short". The transition was too fast to be realistic, or to have given Dawson enough time to turn completely around to face Aunt Gwen.
Continuity mistake: At the beginning, Pacey and Joey are dining at a large table while Pacey is flirting with the woman on his right. Joey goes underneath the table to retrieve her shoe, and sees what is apparently the woman's left hand on Pacey's knee. But the very next shot of the woman above the table shows her right hand up against her face, and her left arm folded, hand on the table. Her left arm doesn't appear to have moved, and there was no time for a transition from Pacey's knee to above the table. (00:00:55)
Continuity mistake: When Dawson is helping Gretchen to hang mistletoe, his arms change position instantly between shots, from laid on the ladder, to above his head touching the mistletoe.
All Good Things... (1) - S6-E23
Continuity mistake: When Jack is pulled over near the start the creek behind him is empty, and remains like that throughout the scene. Then for the last few shots before he drives off again a sailboat has appeared in the background, literally out of nowhere. (00:06:45)
Continuity mistake: In the scene where Jack is fired Jen is limping. She doesn't have the limp in any other scene and never hurts herself, it comes from nowhere and then disappears.
A Family Way - S4-E5
Continuity mistake: When Dawson is coming down the stairs to talk to his parents in the living room, there is a shot of Gail and Mitch on the couch together. Gail is sitting in such a way that her legs are draped over Mitch's legs, and her right leg is specifically hanging over his right leg touching it. But in the next shot, they show Gail and Mitch from the other side of the couch; and suddenly she is sitting with her legs up, bent at the knees and Mitch has his right leg up. There wasn't enough time between shots for anyone to move.
Kiss (aka A Prelude to a Kiss) - S1-E3
Continuity mistake: After Joey finds the visitor Anderson playing a violin on his yacht, they have a back and forth conversation where she hides her work apron behind her back. When the camera angle switches back and forth, her arms are in different positions. (00:14:10)
Pilot (aka Emotions in Motion) - S1-E1
Continuity mistake: In season one. Dawson's door is across from bed, his closet is on the right side in the corner. But then later on in the show his bedroom door relocates to be beside his closet.
Continuity mistake: When Andie and Jack are discussing Ethan's visit while sitting outside eating breakfast, Andie pours milk over her cereal, puts down the milk, takes her spoon in her right hand, then into her left hand. The immediate next camera angle shows Andie holding the milk again, closing it and putting it down, again. (00:06:22)
Pilot (aka Emotions in Motion) - S1-E1
Continuity mistake: In the pilot, Pacey says he has 3 sisters. In the rest of the series he only has 1 sister and a brother. (00:25:36)
Answer: It's only explained once in the series. Jack says to Andie "I tried to start kindergarten without you", meaning Andie was smart enough to start school early.
