Doctor Who: The Doctor Who File (1986)

In this companion volume to Doctor Who: A Celebration and Doctor Who: The Key to Time, Peter Haining unlocks the secrets of the TRADDIS memory banks and explores the history of this influential show through a series of fascinating interviews and specially commissioned articles. From pieces on the creation of the Cybermen, the difficulties in driving a Dalek, and the Doctor Who film that never was, to features on the show's writers — including Douglas Adams who went on to script The Hitch-Hiker's Guide to the Galaxy — and all six Doctors, plus the actors who were very nearly selected to play the role, The Doctor Who File is a fascinating study.
