I believe it has been over 40 years since I saw this series, yet memory of it hasn't faded a bit. This would be a natural for DVD re-issue, it seems to me. Many of the performers have gone on to greater fame (Robert Hardy, Sean Connery, to name a couple); though it was a smallish role, I still remember Judy Dench, then in her 20's, as Katherine of France (Henry V). She was very lovely then as now.
There is a hint on this site that the series was filmed in color - is this so? Who of us would know - virtually no color TV in those days. Mores the pity, no VCR's; if so, some might have recorded it. As a way of teaching English history, this series made it come alive in ways few class room teachers can manage.
What a fine re-issue this would be!
