The target launch date was originally January 1985. Smith and Holland had eleven months in which to write, cast and shoot the whole thing. However, in February 1984, they did not even have a title or a place to film. Both Smith and Holland were unhappy about the January 1985 launch date, favouring November or even September 1984 when seasonal audiences would be higher, but the BBC stayed firm, and Smith and Holland had to concede that, with the massive task of getting the Elstree Studios operational, January was the most realistic date. However, this was later to be changed to February.
