Sorry to take so long to reply - things have suddenly become very busy here! Yes, I do read French, and should be able to manage a French film with French subtitles. I will certainly investigate.

I hope 'Merlin' doesn't disappoint. Since you wrote, Morgause has appeared - she is Morgana's half sister, but Morgana doesn't know about her, and she clearly has some grudge against Uther and interest in Arthur - I suspect that she may turn out to be Arthur's half sister as well, the daughter of his mother and Morgana's father. And I do think that this version, though 'uncanonical' does have inner coherence and might potentially be going somewhere interesting.

I'm afraid I haven't got round to Gawain yet, but I hope to be able to do so soon!
