Dalekmania was the name given to the craze or 'mania' among children in the United Kingdom in the 1960s for all things associated with writer Terry Nation's creations, the Daleks, who were then regularly appearing in the BBC's television drama series Doctor Who.
The documentary Dalekmania starts from the beginning, at least as far as the Dalek movies are concerned, and runs through their history, at the same time interviewing actors like Roberta Tovey, who played Dr. Who's granddaughter in the two films, and Jill Curzon, who played his niece in the second film. There are appearances from actors Barrie Ingham and Yvonne Antrobus, who played the leaders of the Thals in the first film.
The actors give interesting personal accounts of the filming of these movies, including anecdotes about the tough porters who were brought in from Covent Garden Market to play the male Thals and their shock when they learned that they would have to shave their chests and arms and wear wigs and make-up to get into character.
The documentary also reveals that the men operating the Daleks were supposedly not treated particularly well, as none of the other actors can recall seeing anyone get in or out of a Dalek, or ever actually meeting a Dalek operator. They recall fond memories of working with cast members who have since died, including Peter Cushing and Roy Castle.
Script writer and Dalek creator Terry Nation also makes an appearance through archival interview footage, and shares his thoughts on the differences between Doctor Who on television and the Dalek movies. He also explains the pride he took in his mechanical creations, and the lengths he went to over the years to protect their image.
There are also contributions from fans of the films, in the form of Gary Gillat and Marcus Hearn, editors of fan magazines concerned with Doctor Who. They attempt to explain the huge impact that the Daleks have had on the public imagination over the years.
