The Enterprise discovers a historically unrecorded 20th century Earth spaceship traveling through deep space with 72 genetically advanced 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.

Ricardo Montalban had previously appeared in a television movie created by Gene Roddenberry, Chevron Hall of Stars: The Secret Weapon of 117 (1956) (also referred to as The Secret Defense of 117), which was the writer's first attempt to create science fiction on television and aired more than ten years before Star Trek (1966).

The main characters discuss who put the SS Botany Bay on its trajectory. The first suggestion, that it's a prison ship, is dismissed by Spock for the logical reasons that Gene Roddenberry pointed out when editing the script (see trivia). Ultimately the question is simply forgotten. 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.
