and Moray; the alien beings are so powerful they almost destroy Earth by mistake. This script was considered inadequate; the aliens resembled too closely the villains on a typical TOS (Star Trek: The Original Series) episode. Deadlines loomed for special effects production to begin (which required detailed storyboards based on a finished script), which did not exist. Karen Moore, a Paramount executive, suggested that Nicholas Meyer, writer of The Seven-Per-Cent Solution and director of Time After Time, could help resolve the screenplay issues. Meyer had also never seen an episode of Star Trek. He had the idea of making a list consisting of everything that the creative team had liked from the preceding drafts—"it could be a character, it could be a scene, it could be a plot, it could be a subplot, [...] it could be a line of dialogue"—so that he could use that list as the basis of a new screenplay made from all the best aspects of the previous ones. To offset fan expectation that Spock would die, Meyer had the character "killed" in the Kobayashi Maru simulator in the opening scene. The effects company required a completed script in just 12 days. Meyer wrote the screenplay uncredited and for no pay before the deadline, surprising the actors and producers, and rapidly produced subsequent rewrites as necessary. One draft, for example, had a baby in Khan's group, who is killed with the others in the Genesis detonation. Meyer later said: Meyer described his script as "'Hornblower' in outer space", utilizing nautical references and a swashbuckling atmosphere. (Hornblower was an inspiration to Roddenberry and Shatner when making the show, although Meyer was unaware of this.) Sallin was impressed with Meyer's vision for the film: "His ideas brought dimension that broadened the scope of the material as we were working on it." Gene Roddenberry disagreed with the script's naval texture and Khan's Captain Ahab undertones, but was mostly ignored by the creative team. As a gesture of good faith, Paramount changed the film's title from its original working title, The Vengeance of Khan, as it was too close to the working title for Lucasfilm's upcoming Star Wars film. After the name change was made, Lucasfilm changed their title from Revenge of the Jedi to Return of the Jedi. An even earlier working title for the Trek film was The Undiscovered Country, a title which would eventually be used
