GUYSS!! One of the first arthurian tv shows is on youtube (with Spanish subs, but the dub is in English). This is a cheesy adorable tv show about Galahad, with a lot of Mordred in it as well! Every episode is only about 20-15 minutes.
Please, go watch THE ADVENTURES OF SIR GALAHAD. This is adorable!!
Once upon a time (2013?) there was a Mordred webseries (in French and with English subtitles). The webseries was truly amazing and, as far as I know, it had been turned into a movie.
The project was supposed to be three seasons (3 movies), but it has ended with season 2 because of budgetary issues. Still, you might find a summary of what could have been season 3 on the Facebook Page with the scripts of 6 episodes uploaded on googledrive. There is also a book which describes what happened to the main characters between season 1 and season 2.
The whole A Young Connecticut Yankee in King Arthur’s court which features:
Fighting ladies
teenage guy who plays guitar and ends up in arthurian times
Merlin and the Sword is on youtube!! Prepare for kind and cute Nimue&Merlin love story, Ragnelle and Gawain in a weird revisitation, Arthur losing Guinevere’s love to Lancelot, redhaireverywhere!Morgana.
