Did You Know?


William Hartnell decided to play a joke on the cast, who often teased him when he messed up his lines. During one take, when he was supposed to say "The Fault Locator!" he replaced the line with "The Fornicator!" See more »


Susan Foreman: Grandfather?
Dr. Who: Yes, my child?
Susan Foreman: What happened?
Dr. Who: What happened? It was the switch, it was still in place. You see, there's a little spring inside it and it was stuck. It hadn't released itself.
Susan Foreman: But why didn't the fault locator tell us?
Dr. Who: Well, the switch hadn't broken down, therefore, the fault locator couldn't give us any recognition. You see, let me give you a demonstration. Now, look, when I put my thumb on there

Inside the Spaceship Episode 2: Interesting and different interlude in the Doctor's early adventures.
29 June 2014 | by (South Wales, UK) – See all my reviews

Review for both episodes:

This two parter is otherwise known as Inside the Spaceship.

It is an interesting story with a departure from the normal adventures. The whole story is entirely based within the 'spaceship' (TARDIS) and involves strange goings on which lead to all 4 lead characters acting very peculiarly and becoming suspicious and antagonistic towards each other.

There are problems in that while Hartnell as the Doctor acts well and the part of Barbara as ever is portrayed well, both the other members of the crew with their very strange behaviour seem a little jarring at times. Their performances are a bit strained by the unusual material. When being called upon to act in such odd ways and so out of character it makes things very difficult, especially so early after the series creation.

Another problem is the story is not entirely well executed with the mystery and claustrophobic suspicion and suspense working really well at times but being rather illogically and too easily resolved at other times. The first episode is intriguing and holds your attention but can be a bit over the top. The second is more even and well acted but has some strange resolutions to the mysteries.

Overall this is a very good and interesting foray into claustrophobic mystery, not perfectly executed but good stuff in many ways.
