Footnotes
William Hartnell, who played the Doctor in the television series, was reportedly very disappointed to be replaced by Peter Cushing for the film. Peter Cushing was offered the role of The Doctor in the original Doctor Who (1963) BBC television series on three occasions, but he declined. He later regretted that decision.
Freddie Francis was attached to direct at one time (He is thought to have assisted with some casting), whilst Ann Bell was to have played Barbara.
