Like the popular arcade game, Dragon's Lair, it was in many respects a "proper" motion-picture production. It required a full television crew to produce. Judged as a piece of television, it has unusual aspects — it is the only BBC Wales Doctor Who production filmed in a 4:3 aspect ratio. It was the first DWU production for which director Ashley Way and writer Gareth Roberts were credited. It was also the first time that Rory Taylor received onscreen credit as a director of photography.
