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.

The Saurian Brandy container makes an appearance in this episode. The distinctive-shape bottle was actually a modified George Dickel 1964 commemorative edition "powder horn" whisky bottle. See more »


When the Botany Bay is first detected, McCoy indicates that the 'people' on the Botany Bay couldn't be humans because their heartbeats average about 4 beats per minute. Heartbeats would indicate their life processes have been slowed, not completely suspended. At that rate, after 200 years, assuming an average heartbeat rate of 40 beats per minute normally (due to their genetics), they would have aged approximately one tenth of the elapsed time, or 20 years. However, none of the people on the Botany Bay have grown facial hair, or show any other signs of aging. In actuality, they would not have been able to survive without any kind of nutritional intake for that length of time. See more »


Captain James T. Kirk: You suspect some danger?
Mr. Spock: Insufficient facts always invites danger, Captain.
Captain James T. Kirk: Well, I'd better get some facts.

Produces an Interesting Concept; Looks Ahead
28 April 2014 | by HitchcocSee all my reviews

During the first season of the original series there is no way that the producers had a thought about a movie sequel to this series. We all know how tenuous even a second season was for this expensive show. Thanks to the fans they took a chance and the rest is history. In this episode, the charismatic Ricardo Montalban plays Khan, a genetically engineered being whose purpose for existence, along with his crew, is domination. Shades of Hitler and other historical conquerers. The Enterprise and James T. Kirk always seem to err on the side of compassion, and this gets them into hot water in this episode. Upon entering Khan's ship, their suspended animation modules are opened and he fills his lungs with air and starts his conquest. His response to kindness is to manipulate it to his own purposes. His first act when he awakens in sick bay is to threaten McCoy with a knife. McCoy tells him how to sever the carotid artery and this makes Khan laugh and, hence, spare the good doctor. A beautiful young crewman, who has already started to drool over Khan (women weren't always portrayed as that evolved on this show), is enlisted by the manipulator to assist him. He is cruel and she is submissive. She will play a part later. Of course, once he has a foothold, he takes over the ship, bringing his once sleeping crew to the Enterprise, starting to dismantle the ship. The strength of performances and some very good writing help this episode becomes one of the better ones. It is a battle of wits between Kirk and Kahn that makes this work. I need to watch "The Wrath of Khan" again.
