It's hard to believe that it's been a whopping 15 years since Tim Burton's The Nightmare Before Christmas was released. The Buttercup-stealing Humperdink, or Chris Sarandon as Jack Skellington, Catherine O'Hara as Sally, plus a little bit of PeeWee and the wacky Greg Proops -- the days before Johnny and Helena were in everything Burtonesque.

In commemoration of the anniversary, the Collector's Edition DVD hits shelves next week, but to whet our hungry appetites, ShockTillYouDrop has got three clips from the new disc. Check out how they made the Haunted Mansion as a holiday tour led by Jack, the process of shooting the film, and finally, Tim Burton's original poem of The Nightmare Before Christmas, all funky and animated.

It's looking to be one heck of a great re-release. From seeing how Jack's version of the Haunted Mansion played out, to how the film was made, to Burton's old short film Vincent, it's all there. Will it be in your basket come Tuesday?
