The larger truth, however, was that it was a serial that had, unlike most others, been shaped by two different production teams. Along the way it had generated unusual criticism from rights-holders of other properties — including Wiles' own boss — who were concerned that their characters were being unhelpfully, if not illegally, used within the production. In fact, "The Final Test" was the only Doctor Who episode forced to have a continuity announcement to protect the BBC from legal action on behalf of a copyright holder.
