Just a note to clear up some points technically speaking for all of you, since there is so much anguish about the series by the viewers.
This is from an old 1960s BBC TV series, shot the same way and with the same budget as Dr. Who and everything else done by them, these are NOT 'movies'. This means, they were by necessity shot in the studio, on stage, with TV cameras like an American Soap Opera is done to this day. They were recorded therefore, on one inch video tape and switched live, which is done to save tons of money on editing, and uses really good, professional, stage actors who can learn the entire script in one go, and just do it. When exteriors and locations are required they use a film camera, probably 16 mm, to film those scenes, again, like on Dr. Who and everything else the BBC TV networks need to do. If it were not for this technique you would not have had any of this sort of television in England at all. They could NOT afford to film all there TV series like we have always done here in commercial America. The British taxpayers and the TV set licensing system they use actually pays for the main costs of production. See what I mean? So don't compare these types of shows with full budget feature motion pictures, or even American commercial TV series, which are shot on 35mm film and edited for air. This is theatre in the true sense.
I encourage you to get this series because they have added a bonus feature which is VERY expensive to buy on its own direct from A&E Biography, the 1995 documentary on Holmes produced on the death of Jeremy Brett that year. It is really good, and we show it at our annual Holmes Society meeting each January 6th, Holmes' birthday. A&E charges upwards of $30 for this doc (if you can find it); it's about 16 years old now.
