Frank Cox

Frank Cox (born 28 May 1940 ) directed the Doctor Who episodes "The Brink of Disaster," "Kidnap," and "A Desperate Venture". He was also interviewed on the documentary Over the Edge.

Doctor Who was Cox's directing debut, after which he worked on the popular "sci-fact" drama Doomwatch and detective series Paul Temple. He also produced episodes of Sutherland's Law and C.A.T.S. Eyes.

He remains the only Doctor Who director to have never directed an entire story.
