and non-naturalistic". Kennedy Martin, therefore, crafted a serial that on the one hand placed its events squarely within the real, present day world but on the other also placed itself within the realm of the mystical and the mythic. Realism and authenticity was provided by the appearances of real life television presenter Sue Cook and Labour MP Michael Meacher. There was also use of contemporary stock footage, such as Robin Day's interview with Margaret Thatcher and references to real persons like Michael Heseltine and places such as Sellafield, alongside the references to fictitious characters and places contained in the plot. The mystical dimension is provided by Emma's ghost while the mythic is provided by Craven himself and by Jedburgh and Grogan. Kennedy Martin, influenced by John Darragh's The Real Camelot (Thames and Hudson, 1981) which examined the pagan origins of the Arthurian legend, saw Craven as a modern-day Green Man who would confront the threats to the Earth on behalf of Gaia. Jedburgh was conceived by Kennedy Martin as a Knight of the Marches, one of the Teutonic Knights who defended the borders of Eastern Europe, opposed to Grogan, who Kennedy Martin saw as a descendant of the Knights Templar who, according to legend, had guarded a special wisdom in the Temple of the Dome of the Rock in Jerusalem.

The budget was set at £2 million, of which £400,000 came from an American co-producer, Lionheart Television International. Director Martin Campbell came on board shortly afterwards and soon clashed with Troy Kennedy Martin, demanding rewrites, in particular to the notion that Craven had known about Emma's involvement with Gaia right from the start; this was removed at Campbell's behest. Further clashes over the script occurred between Kennedy Martin and star Bob Peck over the conclusion in which his character would turn into a tree; Peck recalled that
