A look behind the scenes of the making of An Adventure in Space and Time, a special one-off drama that travels back to 1963 to see how Doctor Who was first brought to the screen. Actor William Hartnell felt trapped by a succession of hard-man roles. Wannabe producer Verity Lambert was frustrated by the TV industry’s glass ceiling. Both of them were to find unlikely hope and unexpected challenges in the form of a Saturday tea-time drama. Allied with a team of unusual but brilliant people, they went on to create the longest running science fiction series ever made.
