The Stranger (video series)
The Stranger is a series of directtovideo and audio CD sciencefiction dramas produced by BBV and starring Colin Baker. They are now available on DVD.
In Memory Alone, the third film, found the Stranger and Miss Brown stranded without their mysterious transport never seen or referred to as the TARDIS in a desolate train station with amnesia, and battling a robot and a mysterious man played by Nicholas Briggs who also wrote the film along with others in the Stranger series. Most releases of this film including VHS include a behindthescenes featurette and a blooper reel.While the first three may be and usually were taken as Doctor Who by another name, the departure here of the Miss Brown character for which Nicola Bryant had not used her Peri Brown American accent and the Stranger himself being likewise returned to his proper time and place at the storys conclusion allowed for a move to divorce the series from any such notions. The adventures of the Stranger ran in all to six videos and four audio dramas, although the second audio drama was much the same as the sixth video, in the later half of which the series established its own style and distinct back story, abandoning any pretence of being the further adventures of the Sixth Doctor under another name or lack thereof. The Stranger was thus eventually given an identity as the series continuity was tied up. ........
