As Disney celebrates its 100th birthday in 2023, one of its most popular seasonal animations is celebrating an anniversary of its own. Tim Burton’s The Nightmare Before Christmas has turned 30, and fans won’t be surprised to learn that the movie’s happy to jump onto both celebrations with a Santa sack of merchandise. The tale of Jack Skellington, the Pumpkin King of Halloween Town who discovers and takes over Christmas, seems to get more popular every year.
