Production Errors

  1. Jon Pertwee says the line 'I couldn't open it even if I wanted to' twice 

  2. During episode two , a boom microphone appears above Stubb's head after The Doctor shoots the swords out of Varan's hand 

  3. Why doesn't Varan explode when he is sucked into the vacuum of space? And how did Jo, Cotton, Stubs and Ky manage to cling onto the inside of Skybase and survive?  ​​

Working Titles

  • Independence

  • The Emergents


The Mutants feels like a tattier rehash of Colony in Space and does nothing in the way to create a compelling tale of ruthless colonists who need to be taught a lesson or two. The story is nothing to get to excited where messages of pollution and colonisation are thrown about but never seem to mould the story together. There are poor production values throughout and some stick-your-fingers-in-your ears acting from the supporting cast. There are intelligent ideas here, but they are very hard pressed to find in amongst so much filler and constant nonsense. **
