File this one in the rumor pile for now, but Tim Burton might be developing a sequel to his 1993 classic The Nightmare Before Christmas.  In a recent interview [via Dread Central], Paul "Pee-wee Herman" Reubens said he would like to reteam with Burton in the future (the two teamed up for Pee-Wee's Big Adventure), but that the director has a slew of potential projects already lined up.  Reubens then proceeded to rattle off a list of various films Burton was developing and one of them was reportedly a sequel to The Nightmare Before Christmas.Burton's garnered a lot of clout ever since Alice in Wonderland broke a billion dollars at the worldwide box office.  However, his next project is an adaptation of the 1960s gothic soap opera series Dark Shadows starring (who else) Johnny Depp.  Filming on Dark Shadows is set to begin in April.  It's possible that Burton could still be developing a Nightmare sequel on the side, and just like the original, will hire someone else to direct. [Update: Derek Frey, a producer and executive at Tim Burton Productions, tells The Playlist that there is no truth to the rumor.]
