Trivia: A popular film poster shows Emily and Victor reaching their hands toward one another. Emily's bony hand is on her right and Victor's suit and vest are backwards (note its buttons). Some say it was for legal reasons - Johnny Depp's name was supposed to appear on the poster first because of a contract, and they wanted the characters underneath the corresponding star names, hence the issue. Others say it was simply because the picture looked better with the bride on the right side.

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.
Trivia: A subtle reference to this film's 3D format: In Max's box, Trevor finds a pocket stereoscope, which are funky looking glasses that create the illusion of a three-dimensional image from two-dimensional photographs. It was invented by Sir Charles Wheatstone in 1840.
