Out of the Unknown
Out of the Unknown was a British science fiction series.
When he encountered a Dalek, Kennedy thought it looked like the kind of robot that the BBC dreamed up for Out of the Unknown. (PROSE: The Evil of the Daleks)
Behind the scenes
Numerous Doctor Who actors appeared on Out of the Unknown, including Patrick Troughton, Deborah Watling, Bernard Kay and Bernard Horsfall.
Incidentally, the Daleks did appear in Out of the Unknown, in Get Off My Cloud, the final episode of season 3, which aired in March of 1969. The episode's designer was Raymond Cusick, who originally designed the Daleks for Doctor Who.
In fact, Out of the Unknown shared props with Doctor Who in both directions. The White Robots in TV: The Mind Robber were actually repainted dark robots from an episode of Out of the Unknown entitled The Prophet.
Paddy Russell was a director for the series, as was Christopher Barry. Brian Hayles wrote two episodes for the series. Christine Rawlins was a costumer.
