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.
Mordred is a French webseries of two seasons, you can find more here on facebook or watch it on youtube (only some eps of the first seasons have subtitles):
The authors of the series had to finish it at season 2, for lack of resources, but they posted the script of the beginning (or the whole? but I don’t think so) of what could have been season 3!
BTW… if some kind soul wants to write the subs of the episodes…
