• Missing Episode: Although all the episodes still survive, all but one of them only exists as a black-and-white telerecording, the colour film having been damaged in storage. (The third and fourth episodes of "The Day of the Clone" were produced in monochrome due to the 1970 "Colour Strike", and the fifth episode of that serial was produced in colour but broadcast in monochrome due to one of its scenes having to be recorded as a pick-up during production of the strike-affected episodes. All the other episodes were produced in colour, although the strike and the fact that colour TV was still not widespread in 1970 meant that many of them were not seen that way.) The only episode to survive in colour is the final episode of the second serial, "The Time of the Ice Box".
