The final feature film featuring the entire original cast of Star Trek was released on this day in movie history.
Star Trek VI: The Undiscovered County was written by Nicholas Meyer and Denny Martin Flynn and directed by Meyer. The feature film was released in theaters on December 6th, 1991.
In the film, an explosion on a Klingon moon important to the survival of the Empire has led to a potential peace between the Federation and their off-again, on-again adversaries. They send an ambassador to meet with Captain Kirk and the crew of the Enterprise-A. A tense dinner does go by, but then it appears that the Enterprise has attacked the Klingon ship and killed the ambassador! So, Kirk and McCoy are arrested by the Klingons as the rest of the crew works to investigate who the real culprit could be.
The Undiscovered Country, at one time originally proposed to potentially be a prequel film with new actors, featured the entire original cast together for the final time. Aside from William Shatner, Leonard Nimoy, and DeForrest Kelley and the rest, the film also featured Kim Cattrall, David Warner, Christopher Plummer, and Kurtwood Smith. Michael Dorn also appeared as an ancestor to his Next Generation character, Worf. The film also established Sulu as the captain of the Excelsior, the more advanced starship that plays a pivotal role in the film.
The Undiscovered Country was a box office success, making nearly $100 million on a budget estimated to be about $27 million.
