 The few Klingon phrases that James Doohan (qv) introduced in  _Star Trek: The Motion Picture (1979)_ (qv) was used by  Marc Okrand (qv) as the basis for the Klingon language in this  film. Okrands Klingon language became a fully realized fictional  language, and would be the basis for all future Klingon dialogue in  future movies and television shows (as well as an obsession to  become fluent in for hardcore Star Trek fans.)
