The Trailers section of Apple's Quicktime web site for some reason has never added the new Corpse Bride trailer that premiered with Charlie and the Chocolate Factory, however the official site (which is very basic at this point) has.
Click the Video link at the top left of the page here and it's the second trailer.
Of all the films coming up (well, all being Corpse Bride, Serenity, and Doom), Corpse Bride is my most anticipated. Helena Bonham Carter is ever hot, even as a claymated corpse. What?
