The Enterprise comes across the SS Botany Bay, an ancient Earth spaceship from the 20th century traveling through deep space with a group of genetically engineered humans in suspended animation (a remnant from Earth's Eugenics Wars of the 1990s). Visiting this vessel automatically revives Khan, a charismatic Sikh warrior-type with five times the strength and ambition of regular humans, who immediately attracts the attentions of ship's historian Lt. Marla McGivers. While Kirk and Spock slowly learn he is Khan Noonien Singh, the last and greatest of Earth's tyrants, Khan uses both Marla and the ship's library to revive his superhuman compatriots and take over the Enterprise.

Did You Know?


The Augment hypoed by McGivers in sickbay was previously seen as a member of the Alfa 177 science team in Star Trek: The Enemy Within (1966). He is later seen as a Klingon in the final planet scene in Kor's office in Star Trek: Errand of Mercy (1967) and as another Klingon in Star Trek: Day of the Dove (1968). The identity of this extra is not known. See more »


As Khan wakes up, he asks Kirk how long he's been asleep. Kirk answers "two centuries." An answer of "three centuries" would have been much closer to the truth. Kirk would have known that Khan left Earth in the late 20th Century. Star Trek was taking place nearly 300 years later. But this was not decided until Star Trek II: The Wrath of Khan. Gene Roddenberry always left the date ambiguous, and the reference here is directly contradicted by Star Trek: The Squire of Gothos, for example. See more »

A landmark for Trekkers and Trekkies
18 April 2007 | by (Vulcan) – See all my reviews

Space Seed is the first season episode of TOS which gave us Khan Noonien Singh, the eugenics wars back-story, and the situation that culminated in one of the better Star Trek films - The Wrath of Khan. For fans of the franchise, this is a landmark episode which established some important aspects of the history of the star trek universe. For non-fans, it is definitely one of the better TOS episodes, but perhaps not a legend or a classic.

The Enterprise encounters a 200 year old, pre-warp drive earth vessel derelict in space and boards it. Aboard, they find dozens of people in suspended animation. As the ship begins to power up, on of the stasis compartments begins to fail and Dr. McCoy saves the man within from the brink of death. The man is Khan Noonien Singh, a product of genetic engineering. This former world leader has been engineered to be smarter, stronger, and more aggressive than normal humans. What happens is somewhat predictable (except for the excellent finish), but very satisfying because of the Coon and Wilber script, the excellent performances, and solid Marc Daniels direction.

Khan is played with the pure intensity called-for in the role by Ricardo Montalban. Montalban carries every scene away, and Shatner and Nimoy - as powerful as their personalities usually are - do a great job of portraying respectful intimidation.

Highly recommended for franchise fans, recommended for others.
