American novelist and screenwriter (1924–2022) who was a producer on the unmade Star Trek: Phase II and received sole screenplay credit for Star Trek: The Motion Picture.
Harold Livingston was an American novelist and television writer, born in 1924, whose credits included Mission: Impossible.
In 1977 he was hired as a producer on Star Trek: Phase II, the planned second television series, and wrote its two-hour opening script, In Thy Image, from a story by Alan Dean Foster. When Paramount turned the project into a feature film, that script became the basis of Star Trek: The Motion Picture (1979).
The screenplay went through many rewrites, with Livingston and Gene Roddenberry repeatedly revising each other's pages, and Livingston left and rejoined the production more than once. The final credit gives him the screenplay and Foster the story. He died in 2022.
