Following Jim Henson's death in May 1990, talent agent Bill Haber approached his son Brian with the idea of filming an adaptation. Haber told Henson that ""Christmas Carol" is the greatest story of all time, you should do that" and later informed Henson that he sold the idea to ABC as a television film. Longtime Muppets writer Jerry Juhl was hired to write the script and decided to insert Charles Dickens as the stand-in narrator in order to remain faithful to the original prose of the written material. Henson stated that Gonzo was chosen because he was the least likely choice to play Charles Dickens, while Rizzo the Rat was added to inject some humor and serve as a Greek chorus. Established Muppet characters were initially written to portray the ghosts, with various accounts stating Robin the Frog or Scooter was to be the Ghost of Christmas Past, Miss Piggy to be the Ghost of Christmas Present, and Gonzo (before he was written to portray Dickens) or Animal as the Ghost of Christmas Yet to Come. However, the idea was scrapped in favor of new Muppet characters that would better underline the ominous nature. After the script was submitted for approval to ABC, the executives of Walt Disney Pictures offered to purchase the script for a feature film instead of a television release.
