Did You Know?


David Whitaker came up with the idea of a house full of traps. Terry Nation largely transferred this to an exterior setting because the first two episodes had already mostly taken place indoors. See more »

Barbara Wright: It must be far below zero.
Ian Chesterton: Barbara, this wind's blowing right through me. We must move!
Barbara Wright: I can't. I can't move, Ian. I'm too cold.
Ian Chesterton: Oh Barbara, you must move. If we don't find shelter, we don't stand a chance.

The Keys of Marinus: Part 3 - Various locations and adventures varying in quality

Review for all 6 episodes:

This story from Dalek creator Terry Nation begins with the episode the Sea of Death. It is in my view an excellent opening episode. It features an intriguing, well written plot with the TARDIS crew searching a strange planet. The design of the planet and its Voord creatures is very good indeed, ideas such as seas of acid and beaches of glass are cleverly used to create a truly interesting and exciting alien planet. The Voord look good, there is menace and suspense, an excellent alien landscape and building design, a proficient script and quality acting all round which gives a 10/10 opening episode to the story.

However, episodes 2-4 are a little disappointing in comparison. The idea of the story means each episode of the first 5 takes place in a different location with a self contained adventure searching for the hidden Keys of Marinus. This really would be a great idea for a story but is a pity when the original world in the opening episode is so well designed. Episode 2 has a hugely different location and features the crew suffering mind control. This second episode is very good in most aspects but a few less impressive aspects such as a minor plot hole cause its quality to suffer. This plot hole is that Barbara is meant to travel, via a kind of teleportation device, just a minute before the rest of the travellers and yet in that minute before they join her numerous things are meant to have happened.

Episodes 3 and 4 are not as interesting or well executed as the first part either with episode 4 the weakest. Episodes 5 and 6 return to a higher standard and are like a murder mystery. Very good but they still are not a match for the top quality first part.

My Ratings: Episode 1 - 10/10, Episode 2 - 8/10, Episode 3 - 7.5/10, Episode 4 - 7/10, Episode 5 - 9/10, Episode 6 - 9/10
