Star Trek: Planet of the Titans

Star Trek Planet of the Titans, also known as Star Trek Planet of Titans, is an unproduced film based on Star Trek which reached the script and design phases of production. Following the success of Star Trek The Original Series in broadcast syndication during the early 1970s and the popularity of the series at science fiction conventions, Paramount Studios made several attempts to produce a feature film based upon the series. In 1975, Star Trek The God Thing was proposed by franchise creator Gene Roddenberry but was not picked up by the studio.

Following the cancellation of Star Trek The Original Series on NBC in 1969, there were several attempts, influenced by the success of the series in broadcast syndication and from the attendance of fans at conventions, to transfer the series into a film. By March 1972, Roddenberry said that there was interest in a Star Trek feature film and that there was even potential for returning the series to NBC.In May 1975, Roddenberry entered into a development deal with Paramount Pictures to develop a film based on Star Trek. Principal photography was intended to start on July 15, 1976, but was later pushed back to 1977. It was given the initial title of Star Trek The God Thing and had a budget ofmillion. Roddenberrys plot would have reunited the crew of the Enterprise and sent to face God, who was threatening earth. Paramount Studios Chief executive officer Barry Diller ended the development deal in August 1975, although Roddenberry was allowed to keep his office at the studio. Roddenberry pursued the project and invited several others to submit story and script ideas, including his personal assistant Jon Povill, as well as writers Robert Silverberg, John D. F. Black and Harlan Ellison. Ellisons treatment featured the crew forced to travel back in time to prevent a reptilian race from wiping out humanity at the dawn of time. He met with Paramount executives, including Barry Trabulus, who recently read Chariots of the Gods? by Erich von Dniken 1968 and wanted the Maya civilization to be featured in the film. Ellison and Trabulus disagreed, and Ellison left the meeting refusing to have anything more to do with the film. George Lucas later enquired about whether or not Star Trek was available for purchase in order to be turned into a film, and went on to create Star Wars instead. ........
