Visible crew/equipment: Jareth says, "Sarah, don't defy me," and tosses the snake at her neck. In the next shot facing Sarah as she holds the snake, a crew member's hand is seen holding the end of the 'snake' below her right shoulder. (00:13:25)
Visible crew/equipment: When Sarah and Hoggle are in the Bog of Eternal Stench and they almost fall in, look in the top left hand corner of the overhead shot and you will see a boom microphone. (Only on Blu-ray edition). (00:53:40)
Visible crew/equipment: As Sarah, Ludo, Hoggle and Sir Didymus finally walk into Goblin City and reach the fountain, they face the stairs with the surrounding spike walls. In the next two shots, the Goblins appear behind the spiked walls, and in the second shot, on the right, a puppeteer's arm - wearing a short sleeved blue shirt, is amusingly visible under his Goblin soldier puppet; the top of the head of another puppeteer is visible to his right. (01:19:55)
Continuity mistake: When Sarah holds Toby and says, "Knock it off, come on. Stop it. Stop it," her ring is on her middle finger. However in the wide shot, still holding Toby, she says, "I can bear it no longer..." her ring is now on her ring finger. (00:08:30)
Continuity mistake: Just after Hoggle pulled Sarah up, away from the Fireys he is standing by the rope he used to pull her up. In one shot as Hoggle says "Down, go away" the rope is hanging down off the ledge, but in the next shot, all the rope is pulled up, away from the ledge, and is in one big heap. (00:52:30)
Continuity mistake: Sarah sits in her fake room, picks up the book, 'The Labyrinth' and is seen in her reflection. She then says, "Through dangers...take back the child you have stolen." When the Junk Lady asks, "Don't you like your toys?" and also when she gives Sarah the music box, Sarah is seen. In each shot the things behind Sarah's shoulders and in front of her are different, yet, the Junk Lady did not add anything between these shots. (01:13:10)
Visible crew/equipment: At the start of the film, when Bowie sings the word, "Underground," the last word of the song, it's just at that moment the screen goes from black background to a backdrop of trees in the real park, which is the same moment the animated owl turns into a real owl, the wire attached to the real owl's left foot is visible. There is a jess (strap) around its left foot, that is also clearly visible when he lands on the obelisk in the park. (00:02:40)
Continuity mistake: When Sarah angrily goes into Toby's nursery to retrieve Lancelot, as she screams, "I hate you!" to Toby, who is in the crib, the crib's legs are visible and there are NO casters (wheels) attached to the legs. However, in the rest of the shots, whenever visible, there are ball bearing casters on the legs of the crib. (00:06:50)
Continuity mistake: When Sarah sees Toby in the Escher-style room, she jumps of the edge of the platform. As she jumps off, she raises one leg behind her other, yet in the next shot her legs are beside one another. (01:26:45)
Continuity mistake: At the start of the film, as Sarah runs across the bridge, there is a curve in the right side of the river bank which is just grass. However when Sarah runs back across the bridge, that area is now filled with bunches of tall white flowers. (00:02:45 - 00:03:55)
Continuity mistake: As Sarah starts to run down the labyrinth, just after she's entered it, the ribbons on the back of her jacket go from tied to loose then to tied again. (00:18:45)
Continuity mistake: When Sarah is putting lipstick on, the newspaper clippings and photos on her mirror change position and arrangement between different angles and shots. (00:06:05)
Continuity mistake: When Sarah shows Hoggle her plastic bracelet in the oubliette, when trying to get him to take her as far as he can to the centre of the labyrinth, in one shot she holds the bracelet between her finger and thumb, then in the next shot it is dangling off her finger. (00:31:05)
Continuity mistake: When Sarah is telling the story to Toby, she stands in front of the mirror, and puts Toby's stripy hat on. In one shot, she pulls it to the back of her head, but in the next shot, it's pulled down on her head, as normal. (00:07:40)
Trivia: This is only on the DVD. As Hoggle walks off saying "There's one thing for sure, she'll never get through the labyrinth" look at the top left corner of the screen and you'll see the face of Jareth (David Bowie.) You see his face again, when Sarah and friends are walking through the forest, and Sir Didymus says "We should reach the castle well before day." Look at a tree to the right of the screen and you'll see the face.
Continuity mistake: When Sarah walks into the darkened bedroom, in the shots facing the double back doors the hanging light fixture over the crib, the mobile, and picture beside it are all visible. When Jareth appears, in the first shot facing him, the mobile hangs lower (note the archway), the picture is closer to the floral trim around the archway; and solely for Jareth's dramatic entrance, the light fixture is gone - though it should easily be visible in this shot, and the crib is now at an angle. (00:10:25 - 00:11:55)
Continuity mistake: When Sarah is hanging on the branch over the bog, Ludo calls a rock and the rock rolls into the bog, and is pretty round, with no large flat areas on it. However when it's floating in the bog, Sarah jumps onto it and the rock now has a very large flat area. (00:58:45)
Continuity mistake: Sarah goes to pick up the fairy that dropped right by the wall. But in the next shot, you see Sarah stand up with the fairy in her hands, and she is now standing quite a way from the wall. (00:14:55)
Revealing mistake: During the 'Dance Magic Dance'-sequence in Jareth's throne room, David Bowie throws up a baby dummy (it's near the end of the song). (00:26:00)
Continuity mistake: When Sarah first enters the labyrinth, and is running down the passage, the branches, bits of log and wood etc., change, disappear and reappear between different angled shots as she runs. (00:17:45)
Answer: To add to that, the other door was supposed to lead her to certain death, and technically the oubliette wasn't exactly certain death.
