I also have found, if vague, memories of watching this on PBS in New York in the early 1980s. These versions of Robin Hood and King Arthur, among other legends, were free of the cheesiness and camp of sword-and-sorcery movies of that time and foreshadowed the low-magic, human-scale dramatic (but not melodramatic) approach of TV and movies such as the more recent "Cadfael" and "King Arthur."
I, for one, would love to see these available on DVD in the U.S., and I'd be happy to sign any petitions, but I don't know how many people are aware of this version of "Robin Hood." The reasonably well-done version of a few years later with Michael Praed and Jason Connery (plus more New Age trappings) is better known.
Here are some titles inspired by "The Falcon and the Winter Solider" that bring back Peggy Carter, explore mysteries with a few MCU mainstays, and feature a buddy-cop duo who clash as hard as Sam and Bucky.
