Sally Originally Went Full Corpse Bride In The Nightmare Before Christmas

The tale behind "The Nightmare Before Christmas" is almost as legendary as the movie itself. The film is based on a poem and sketches by Tim Burton, and Henry Selick was hired to direct a film. "Beetlejuice" writer Michael McDowell was then hired to write the script, and frequent Burton collaborator Danny Elfman was brought on to write the film's songs.

Elfman completed his task, but McDowell was unable to complete work on the script. Because of this, "Edward Scissorhands" writer Caroline Thompson was brought in to adapt the screenplay based around Elfman's songs (via Script Apart).

According to an interview with The Hollywood Reporter, Selick started filming before the script was finished; the songs, on the other hand, were complete. However, due to this, Sally's original story fell by the wayside. "Danny pretty much told the story in the songs, so it's like, 'Okay, what's left?' And what's left is Sally's story," Thompson said in an interview with Jog Road Productions.
