Regenerations: From Black and White to Colour

Spearhead from Space marked not only the arrival of a new Doctor but also the transition from black and white to colour as the show moved into a new decade. This documentary looks at the challenges faced by programme makers during this period, with actors Frazer Hines and Wendy Padbury, producer Derrick Sherwin, script editor Terrance Dicks, directors Timothy Combe, Christopher Barry and Michael Ferguson, designer Roger Cheveley and graphic designer Bernard Lodge.
