Harlan Ellison wrote City on the Edge of Forever for Star Trek, which was never used in its original form. It took more than ten months for Gene Roddenberry to rewrite Ellison's work. Steven W. Carabatsos and D. C. Fontana, both story editors on the show, undertook re-writes of the teleplay, and changes have also been attributed to producer Gene L. Coon. The experience led to animosity between Ellison and Roddenberry for the rest of the latter's life, in particular over a claim by Roddenberry that Ellison had the character Scotty dealing drugs in one version of the script. We read Harlan Ellison's original script.
