Production Errors

  1. During episode one you can see Norman Comer's eyes (Ichtar) blinking behind his costume's head

  2. Why does The Doctor want to go to Sea Base 4's control centre when there is nothing wrong at the moment. The Doctor could have just gotten in The Tardis and left.

  3. The left airlock doors clearly states: "TO OPEN: Open other door first", whilst the right door states the EXACT same thing. So which door do you open first?​

  4. In episode three, the 'Silurians' are clearly wearing T-shirts under their neck sections

  5. When the Silurians die from Hexachromite gas, a zip can be seen on one of the costumes

  6. Somehow Vorshak knows the name of the 'Sea Devils' without having heard their name prio

  7. Tegan somehow acquires a bra between episode one and two

  8. Tegan's leg injury healed rather quickly throughout the serial, and she stops limping in episode four​​

Working Titles

  • [no known working titles]


Warriors of the Deep is frustrating because it combines many original elements but fails to live up to its full potential. A Sea Base under siege, the crew member who is a secret villain, monsters from the deep who want global control what could go wrong? The plot seems so desperate to get going that it literally throws the Silurians and Sea Devils into the mix straight away. The return of the classic pre-historic villains is overdue, and their new designs broadens their universe rather than repeats it. The lighting of the Sea Base sets are far too brightly lit and would have benefitted with a darker atmosphere. The sets are clearly pushing the boundaries whilst the direction is a bit sloppy at times but does disguise the reused corridors sets over and over again. The Myrka is bad! Really bad. It lumbers about killing people with no effort and looks like it is just going for a stroll. The continuation of human ignorance against the Silurians is well performed with ideas such as mistrust, prejudice and worry thrown about. The ending is strong where The Doctor realising that a peaceful treaty is not possible who must resort to harsh options to save the day but even te brave act can save this desperate adventure from survival. Disappointing tale which can be summed with up The Doctor saying ‘There should have been another way’. ***
