In 1968, writers Bill Raynor and Myles Wilder were hired to write the script, and completed their outline in October. They submitted their outline to the studio for review, but the project continued to languish in development. In 1975, producer Jerome Courtland re-discovered the project and hired writer Malcolm Marmorstein to write the script. For his script, Marmorstein revised the story from being in contemporary time into a period setting, and had the dragon changed from being wholly imaginary into a real one. In earlier drafts, Elliott was mostly invisible aside from one animated sequence, in which Dr. Terminus would chop up the dragon for his get-rich scheme. However, veteran Disney artist Ken Anderson felt the audience would "lose patience" with the idea and lobbied for Elliott to be seen more in his visible form during the film. In retrospect, Marmorstein conceded that "We tried a completely invisible dragon, but it was no fun. It was lacking. It's a visual medium, and you're making a film for kids." He also named the dragon "Elliott" after actor Elliott Gould (who was a friend from his theater days), and named the town "Passamaquoddy" after the real Native American tribe in Maine.
