Our Review

What Star Trek VI: The Undiscovered Country Is About

Star Trek VI: The Undiscovered Country (1991) is a sci-fi and thriller film produced for Movies that premiered on December 6, 1991.

It stars William Shatner, Leonard Nimoy, DeForest Kelley and Kim Cattrall.

What to Expect When You Watch

It runs about 110 minutes and it leans into its sci-fi/thriller roots while leaving room for the quieter character beats.

Performance-wise the film leans on William Shatner, Leonard Nimoy and DeForest Kelley to carry the emotional weight, with the rest of the ensemble filling out the world around them.

Cast and Creative Team

William Shatner, Leonard Nimoy, DeForest Kelley and Kim Cattrall lead the cast.

Key roles include William Shatner as Captain Kirk; Leonard Nimoy as Spock; DeForest Kelley as Dr. McCoy; Kim Cattrall as Valeris.

Why It Stands Out

Fans of sci-fi and thriller have a clear reason to give this one a shot. It sits comfortably alongside Movies’s other originals, a 7.3/10 audience score puts it in steady company and it commits to its premise instead of hedging between tones.

Released in 1991 and carried by Movies, it lands hardest with sci-fi and thriller viewers.

How Star Trek VI: The Undiscovered Country Compares

If Star Trek VI: The Undiscovered Country lands for you, the next stops are The Empire Strikes Back, Star Wars: A New Hope and Spider-Man: Across the Spider-Verse (2023), which share its sci-fi/thriller lean.

Each of those sits at a different point on the same spectrum, so they make a natural follow-up once you finish the run here.

Where to Stream

On the whole Star Trek VI: The Undiscovered Country is the kind of film that rewards a patient watch, with William Shatner and Leonard Nimoy doing the heaviest lifting, a tone that stays true to its sci-fi/thriller roots, It has held up since 1991 and so if the premise sounds like your lane, the execution holds up.

The Bottom Line

Star Trek VI: The Undiscovered Country is a safe bet for anyone already inside the sci-fi and thriller lane, the audience score holds around 7.3/10 and so there is little risk in starting it tonight.

Verdict: 7.3/10. Watch it if you want sci-fi/thriller you can settle into.
