Exploring the upcoming Coraline's literary origin, Focus Features has whipped up some rather gorgeous posters. Each features a letter of the alphabet, highlighting something about Coraline and the worlds she inhabits. Twenty-six websites got their own unique poster, with Rotten Tomatoes getting the "R" treatment. Check it out!

Coraline, directed by stop-motion maestro Henry Selick from a novel by Neil Gaiman, tells the whimsically dark tale of a girl who finds a doorway into a parallel world, whose fantastic delights slowly give way to some rather sinister underpinnings. You can browse our image gallery here, or some behind-the-scenes and trailer videos here.

And in the spirit of traveling to the twisted, horrible places beyond, here are links to the other sites participating in the promotion.
