Dr. Zachary Smith: Safely aboard. You will take off immediately.
The Robot: I will need time to study the controls.
Dr. Zachary Smith: You may have exactly five seconds. Well? What are you waiting for?
The Robot: I must scan and compute control systems. I do not wish to make an error.
Dr. Zachary Smith: You always have to make a problem out of everything, don't you? It's all perfectly simple. This one probably starts the power system.
The Robot: Warning. Do not tamper with alien controls.
Dr. Zachary Smith: Nonsense. Any one of these could whisk us away from here.

Part Two Continues To Shine
13 February 2015 | by See all my reviews

An alien known as The Keeper (Michael Rennie) wants to add Will and Penny to his collection of space creatures.

Over the decades I have spoken to many Lost In Space fans and I am yet to find someone who dis-likes this two-part adventure.

Some fans have compared it to classic Star Trek's The Cage which was also about humans held captive by aliens. Some fans have compared it to the movie The Day The Earth Stood Still (1951) which also had Rennie playing an alien.

This 100 minute Keeper adventure is close to perfect, with the whole regular cast getting things to do, the only small negative is a two minute bit (in Part Two) where a very fake giant spider attacks the group.
