We bought Coraline on DVD for our children (4 and 1) to watch this holiday period.
It's an awesome film, but not what I'd consider a traditional children's movie; what with the dead children, mutilation and horror.
The plot, briefly, is Coraline feels ignored and unloved by her parents, and discovers a passage way to another world, like our own, but better.
There she meets her Other Mother, who is prettier, nicer and a better cook than her real mother, and her Other Father, who is more fun and attentive than her real father.
The only jarring point is that everyone she meets in this other world has buttons instead of eyes.
Soon Coraline's Other Mother is inviting her to stay in the Other World forever. All she needs to do is replace her eyes with buttons (black is traditional, but they could be any colour she wants).
From there we meet the ghosts of the previous children who sewed buttons into their eyes, a talking black cat and see The Other Mother's true form.
Coraline must then save her real parents and retrieve the lost souls of the dead children (who were eaten by The Other Mother).
After watching the movie, I started thinking "This would make a kick ass Changeling: the Lost game".
The Other Mother serves as a member of the Gentry, luring children into Arcadia with promises and illusion before forcing them to accept a contract (the buttons) and imprisoning them.
She even manufactures Fetches out of sack cloth and sawdust.
The tunnel that Coraline crawls through to get to the Other World can only be opened by a special key, and is a fixed gateway to Arcadia.
I doubt that a whole Changeling campaign could be made of the film, definitely a story arc with incumbent Fae villain.
The players Motley learn that children keep disappearing from an old house, and suspect that a True Fae is involved. One child has escaped, and has now become an Elemental Mannequin, with visible seams and buttons for eyes.
One of the missing children could be linked to a member of the Motley, or maybe the house. The escaped child could even be a member of the Motley.
