Doctor Who (1963–1996)
The Web of Fear (1)
S5 E23:
The earliest available appearance of Patrick Troughton as the Doctor. The Doctor once again crosses paths with the robotic Yeti from the earlier Doctor Who adventure "The Abominable Snowmen”, and with the alien – the Great Intelligence - who controls the monsters. The adventure begins when the Doctor investigates some unusual activity in the contemporary London subway system - little realizing that there's more to this case than a few renegade commuters who refuse to pay their fare!
