Frank Cox

Frank Cox (born 28 May 1940 ) directed the Doctor Who episodes "The Brink of Disaster," "Kidnap," and "A Desperate Venture."

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 was married to Bridget Turner, who played Alice Cassini in the Doctor Who television story Gridlock.

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