Continuity mistake: The first three episodes have zero continuity when it comes to Piper's love life. In Ep1 "Witch Trial" Piper is hooking up with the guy who is looking at the loan for P3. Then in Ep2 "Morality Bites" she is with Leo (presumably they have secretly been together for months as they discuss their many issues being able to talk when they're both so busy with magic crises and how Leo hasn't figured out how they can be together without clipping his wings). But by Ep3 "The Painted World" Piper and Dan are already together. They has been no discussion of Piper and Leo breaking up and zero mention of Piper and Dan getting together (in fact, the last time we saw Dan in Ep1, he and Phoebe were flirting pretty heavily). I am so confused and I do not at all remember these inconsistencies from when I first watched these episodes years ago. Were these shot and aired out of sequence or something?
Suggested correction: Your last statement is correct, which also invalidates your error. Ep3, "The Painted World" was produced before Ep2, "Morality Bites" but "Morality Bites" was aired first, out of sequence.
Suggested correction: Piper and Dan weren't together in The Painted World, they weren't together until she's a man, baby, a man. When Piper sees his dating tape.
Witch Trial - S2-E1
Visible crew/equipment: While the Book of Shadows flips its pages the sisters enter the attic, and after Piper asks how the book does that, in the next shot the feet of a crewmember can be seen moving quickly out of shot, at the bottom left side of the screen. (00:03:15)
Witch Trial - S2-E1
Continuity mistake: When the book was taken, Phoebe has her necklace above her shirt, but when she runs downstairs, her necklace is underneath her shirt and then is back on top of her shirt again. (00:06:15 - 00:18:25)
Witch Trial - S2-E1
Continuity mistake: At the spiritual place Phoebe had tan marks, but later on she didn't have any tan marks. (00:10:35)
Continuity mistake: Phoebe was the first to get out of the kitchen, then Piper followed, and last was Prue, but when we see them running to the window, Phoebe is first, then Prue then Piper. (00:00:40)
Continuity mistake: In 'Morality Bites', Phoebe has her premonition about being executed while watching a news report on a baseball player, right after she and the others punish Pratt. When she returns in time at the end of the episode, they all watch the news report first and only afterwards look out the window and see Pratt. (00:02:10 - 00:39:50)
Visible crew/equipment: While Phoebe begins her "fifteen minutes of channel surfing" she has the burning premonition and cries out, then in the next shot as Prue and Piper rush in, we can see the reflection of the boom mic/pole in the wall mirror. (00:02:10)
Continuity mistake: When Prue, Piper, and Phoebe return from the future, Prue and Piper hug Phoebe in relief. In the following shot, Piper wraps her arm around Phoebe again. (00:39:20)
Factual error: Phoebe is going to be burned at the stake for witchcraft like they're starting the Salem witch trials again, but witches weren't burned, they were hanged.
Visible crew/equipment: Just after Piper freezes the security guard after she and Prue enter the prison, they are walking along a corridor and the shadow of a boom mic can be seen in the top left quadrant of the screen.
Continuity mistake: When Piper writes the name "Nell" backwards on the castle window she uses two fingers so each letter is doubled lined, but when the name is viewed from the outside all the letters are single lined. Additionally, after she writes the backwards "N" on the bottom right window, in the next closeup of the swords' pointy ends that window is blank. (00:30:20)
Continuity mistake: Phoebe had to touch both Jane and Malcolm for them to be trapped in the painting, so how come she didn't have to touch Piper and Prue for them to all be freed? (00:39:25)
Revealing mistake: When the sisters are talking in the kitchen about Phoebe crashing Prue's car, whenever Phoebe turns around you can see a distinctly grey patch of skin on her shoulder where one of the actress's tattoos is covered up.
Visible crew/equipment: After Prue gets off the phone with Barker and tells Phoebe about it, when Piper runs into the kitchen with the news about Dishwalla, the reflection of the moving boom pole can be seen on the glass cabinet. (00:10:00)
Continuity mistake: When Leo comes to the manor to tell Piper about Masselin, during the conversation Prue is not wearing her choker in the shots facing her (with her arms crossed) and Phoebe, but in the next shot when Leo tells Piper that he knows she's upset we see Prue's choker suddenly around her neck. (00:11:50)
Continuity mistake: After Phoebe tells Piper about the balloon plan, when Piper starts talking about Leo she fills the blender on the counter, and in the two shots facing Piper the white lid is on top of the blender, but in the shot facing Phoebe the lid is gone before she turns it on. (00:19:10)
Continuity mistake: After the potion is spilt, the green stain it leaves on Phoebe's skirt keeps changing both size and colour. (00:31:30 - 00:34:35)
Continuity mistake: When Prue leaves Buckland's, she's wearing a red tank top, but when she arrives at Camp Skylark, her shirt is different, both in style and color. She can't have stopped to change, because it's mentioned she left the auction house and headed directly to the camp. (00:07:00 - 00:09:20)
