When the Firey's are singing there's a close up of one of them and he opens his mouth really far and you can see through his mouth to the background.

From one camera angle in the movie, where Sarah kisses Hoggle and they almost fall in the Bog of Eternal Stench, they can be seen popping back out again!

After Sarah pulls Hoggle away from the edge of the cliff leading to the Bog of Eternal Stench & Hoggle asks why she kissed him, the rocks below their feet cave out & the camera view switches to show them falling. Well, for a few seconds in that view, a boom mic can be seen on the top of the screen!

Just before the worm directs Sara to 'try walking through it' about the wall across from her, she has just finished throwing a little fit about the path going 'on and on' and she hits the walls on BOTH sides and at that time there was no passage.

During the scene with Jareth dancing with Toby to "Dance Magic Dance" (or whatever that song is) you can see at two points that the baby he is holding is not real. The doll has lots of blonde curly hair.

When Sarah throws her lipstick at her mirror in her room, it magically appears in her pocket again when she is walking around the labyrinth and writing on the tiles.
During the scene in Jareth's castle with the goblins, as he is singing and jumping around, the strings from the goblins can be seen across the light from the window.

When Hoggle makes his daring attempt to stop the goblin driving the big metal goblin, he jumps off after making the robot break. When he lands, he barely hits the large spikes at the edge of the wall, but they wobble; they're obviously not real! :)

In the scene where Jareth gives the peach to Hoggle, the first shot of Jareth in front of the tree shows fake birds on the branches. You can tell by the way they move - a la "Wizard of Oz". But in the next few shots of the birds in that scene, they're real.

When Sarah breaks out of the crystal ballroom and is falling through space there is a point when you see the wire she is hanging from.
At the end of the movie when Sarah recites the lines that make the goblin king turn into an owl she leaves out the sentence 'To take back the child that you have stolen'. She practices this at the start of the movie in the park when we first hear her say the words.
During the scene where everyone is fighting the giant metal goblin robot the great dog Ambrosius bumps the "metal" spikes and shakes them around making them look quite fake.
In the magic dance scene when Jareth is seen throwing Toby into the air, he stumbles into the goblin to the left..
