Having been hospitalized for several weeks, Star Trek creator Gene Roddenberry dies in a Los Angeles hospital; his health had been declining in recent years and he had become confined to a wheelchair, leaving much of the day-to-day production duties of Star Trek: The Next Generation executive producers Rick Berman and Michael Piller. Roddenberry is survived by his son and by Majel Barrett Roddenberry, who still occasionally guest stars on Star Trek: TNG as Lwaxana Troi, and fans the world over mourn his passing. Rick Berman is expected to continue assuming full responsibility for the Star Trek franchise’s production and creative decisions, a role he had already been fulfilling during Roddenberry’s recent years of ill health. TNG is currently in its fifth season.

The first Star Trek film since 1982’s Star Trek II to be directed by Nicholas Meyer, Star Trek VI: The Undiscovered Country premieres in theaters, with Paramount billing it as the final appearance of the original crew. Depicting the earliest hints of a political alliance between the Federation and the Klingons, Star Trek VI is intended to hint at the future already playing out on TV on Star Trek: The Next Generation, and is preceded by a special two-part episode of that show featuring Leonard Nimoy. While some of the cast reprise their roles in later movies, TV episodes and even fan-made productions, this does mark the final appearance of DeForest Kelley in character as Dr. McCoy.

Paramount formally announces plans to launch another Star Trek spinoff, Star Trek: Deep Space Nine, in 1993, with filming to begin later in 1992. With casting yet to be finalized and the series concept still in flux, the public’s first glimpse is a year away; many trade publications still list Michelle Forbes’ TNG character, Ensign Ro, as one of DS9’s main characters. The series will be the first Star Trek entity not created by the late Gene Roddenberry; instead, TNG showrunners Rick Berman and Michael Piller have created the show’s concept, which is said to be “darker and grittier.”
