In addition to her own writings, Fisher was sought after as a "script doctor"—a writer brought in to fix weak places in dialogue, scenes, and timing on screenplays. Fisher was quietly lauded for the work, with Entertainment Weekly calling her "one of the most sought after doctors in town." You won't see her name in the credits for her work, however. Fisher did her job under the radar, fixing scripts for a multitude of projects, including Hook (1991), Sister Act (1992), Lethal Weapon 3 (1992), The Wedding Singer (1998), and even the Star Wars prequels. Despite her prowess with a pen, the photo circulating since her passing that supposedly show Fisher's handwritten notes on the Empire Strikes Back script is reportedly a farce. While she did rewrite some of her dialogue on all three of the original Star Wars movies, the notes on the script actually belong to director Irvin Kershner, according to ComicBook.com.
For a while, script doctoring was a lucrative job for Fisher, but she stopped as the method of submitting rewrites changed over time. "Now in order to get a rewrite job, you have to submit your notes for your ideas on how to fix the script," she told Newsweek. "So they can get all the notes from all the different writers, keep the notes and not hire you. That's free work and that's what I always call life-wasting events."
