Black Angel (1980)
A bit of a stretch to call this a "movie," given its length, but still.
Fantastic visuals--the Black Angel and the fay-woman accompanying him are superb, with a strong Excalibur vibe. Also the protagonist's costume and his burned-out castle seem to have been a big influence on Robin Hood Prince of Thieves.
4 out of 5 plague-ridden peasants, with one deducted for the cliché ending taken straight from Ambrose Bierce.
