Although low-budget, this was a great series, perhaps even a bit of a minor cult, at the time. It was well cast (even to the point of bringing in a German actress to play Rowena the Jute) and beautifully acted. Alas, 'Arthur of the Britons' has not been repeated on U.K. television since the 1970s. I kept the guide short, as memory can be a bit unreliable.
One video compilation was issued and is still about - you can occasionally find it on eBay - but other than that there has never been a complete issue on video or DVD.
With all the old drama now surfacing on some of the new television channels, 'Arthur of the Britons' should definitely be taken down off a dusty shelf somewhere and given another outing.
