There is also a German silent film made in 1924 "Die Nibelungen" that managed to condense the story down to a mere four and a half hours. While being a long movie it is still impressive to watch.
There is of course Anna Russell too: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eN5dAQLYYrs.html I'd say the Boulez/Chéreau Ring is a great start. It has great characterizations, the singers also look the parts rather well (no 100+ kg Valkyries) and the direction is not too wild.
Anna Russell was my inspiration for this entire channel!!! I am in love with her!!!! And yes completely agree I've watched the Boulez/Chereau production maybe 5/6 time by now...
