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 clearly see a boom microphone.
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!!
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.
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.
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.
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.
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.
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).
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.
