Dr Who, in his time and space machine, arrives in London in A.D. 2150 to find it ravaged after a Dalek invasion. The earth’s cities have been razed by meteorites and cosmic rays and human beings have been turned into living dead men called Robomen. Prisoners have been taken and forced to work in a secret mine as slaves.It is all fairly naive stuff [from the BBC TV serial created by Terry Nation] decked out with impressive scientific jargon. Peter Cushing, as the professor; Jill Curzon, as his niece, and Roberta Tovey, as the granddaughter, have learned to play it with the necessary seriousness. Bernard Cribbins as the policeman provides some amusing light relief.
