Hi, I'm trying to find the title of either a film or television series. It was about King Arthur. I saw it in the early to mid 70's on TV. The only bit that I can clearly remember was either Lancelot or Arthur at the very end went to visit Guinevere at the nunnery she was in years later. She then said that she had kept Excalibur and produced it from under her bed mattress and gave it to Lancelot / Arthur. Have checked out quite a few Arthurian films, but can't seem to find this one. Hoping you can be of help. Many thanks.
