Did You Know?


This episode was Roger Delgado's final appearance as The Master. Due to time constraints in the studio his final scripted scene was not taped. Delgado was due to reappear as The Master in Series 11, but was killed in a car accident while in Turkey for a film called "Bell of Tibet.". See more »


Due to an unfortunate decision to place a glass table in front of the yellow Chromakey panel which serves for the President's video / TV screen, part of Congressman Brock's broadcast can be seen superimposed onto the table. It is not being seen through the table, as there is also a black chair in between the screen and the table. See more »


Dalek Voice: [over the radio] We are about to enter hyperdrive and return to our base. Do not fail the Daleks.
[the transmission ends]
The Master: Right, we'll see who rules the galaxy when this is over. Do not fail the Daleks, indeed. You stupid tin boxes.

Space opera epic of excellent quality and with a surprise swansong for a great villain.
16 October 2014 | by A_Kind_Of_CineMagicSee all my reviews

Review of all 6 episodes:

Frontier in Space succeeds where The Space Pirates failed, it is a very good adventure in 'space opera' epic style. There is very good model work in both stories but unlike its predecessor the model work is matched by almost all other aspects in this story being of a very high standard.

Proceedings begin with The Doctor finding himself in the middle of a very tense situation between two powerful empires in the galaxy on the brink of war. Earth's empire and the Draconian empire both believe the other is attacking them but The Doctor and Jo find there is another power orchestrating events to bring about a huge war. The Ogrons, under orders from an unknown superior, are in fact carrying out the attacks with hypnotic signals causing them to be wrongly identified.

Spoiler alert - There are a couple of wonderful surprises as the story develops as first The Master is revealed to be behind the scheme to provoke war and finally it is also revealed that he is working with The Daleks. These revelations and the excitement of seeing two of The Doctor's greatest enemies working together provide huge enjoyment.

The Draconians are famous for being Jon Pertwee's favourite aliens and are well thought of by most reviewers ever since. This is well deserved as they are truly excellent alien creations. The make up and costuming is brilliant and convincing and their acting lives up to the excellent presentation on screen. The writing of them as a sympathetic alien race with some depth just adds even further and makes them one of the best created races in the series history.

The plot meanders a bit too much with too many captures and imprisonments but that is the only real flaw until a slightly dodgy space walk in episode 4 and then a tragically chaotic final scene for The Master in episode 6. Chaotic because it is badly edited and shambolic leaving you wondering why the Ogrons and The Master disappear in such a rapid and unconvincingly feeble way. Tragic because this is the last scene ever with Roger Delgado as The Master. Delgado was very sadly killed in a car accident meaning that when The Master eventually returns to face the 4th Doctor he is played by another actor.

Although his final few seconds on screen are somewhat ruined this is a fitting story for Delgado to finish on. It is an excellent, well written and exciting adventure with good twists and great aliens.
