TItans has been a pet project of mine for some years and I've done a fair amount of research trying to pin down its history from various contradictory accounts and interviews. I've contacted several people who worked on it, but it's been so long they recall nothing about it. But here's what I can tell you with some confidence: The treatment Paramount approved was titled Planet of the Titans in October 1976. By the start of 1977 the film to-be was titled Star Trek—The Motion Picture. To date I know of no one who has ever seen a script, and there are conflicting account as to if there ever was a complete script. Some sources state a 1st draft was delivered before screenwriters Bryant and Scott’s exit on March 18, 1977 and was apparently rejected by the studio. The writers stated they were trapped between Roddenberry and Kaufman's conflicting ideas about what the film should be, Kaufman wrote at least one (undated) treatment, presumably after the Scott-Bryant exit. Kaufman was working on the story on May 8, 1977 when Jeffrey Katzenberg called to tell him the film was cancelled. Star Wars came out 17 days later. Ralph McQuarrie worked on the film under Ken Adam in London for ~6 weeks, but never saw a script.
