If they did a King Arthur story in the future, I'd prefer it to be a TV show that covered the story as accurately as possible (while updating and adding new material where needed) as I think it could be entertaining and I would love to see some of the stories about Arthur's Knights be shown - like the story of Feirefiz; a mixed race knight with very awesome armour, and Galehaut; the 'uncrowned king' who tries to conquer Arthur but is so mesmerized when he sees Lancelot fight that he surrenders in exchange for becoming Lancelot's friend - with it never been made clear if he just really likes Lancelot or if his feelings are more romantic.
Like I said, it could make for some good stories, good drama, good comedy, good action and a fair amount of heart.
(See my two videos above for more information)
Alternatively for King Arthur, we often hear the legend that he is "The Once and
Future King" and that when Britain is in its greatest time of need, he will rise again in the role of a Messiah to save his people. Even the TV series
Merlin - which did its own take on the Mythos - pointed this out in the final episode:
We've had one or two attempts at this such as the comic Camelot 3000, which showed King Arthur and Merlin returning in the year 3000 (
where we don't live underwater) to battle an alien invasion masterminded by Morgan Le Fay - with Guinevere, Mordred and King Arthur's knights all reincarnated into different people. However, we've never had a TV/Movie version of a story that depicts Arthur returning to the modern day - which again I think could work.
Some people have said King Arthur - or indeed any of the other "
Kings in the Mountain" who are supposed to return - coming back would be pointless because he would still have his medieval mindset in a world which has moved on and he would likely be arrested if he retrieves Excalibur for walking the streets while carrying a weapon (trust me - there are a fair few arguments like this and Monty Python probably said it best).
With that out of the way, however, it's said that Arthur is only sleeping until the day he's needed (and presumably this is an ageless sleep). Well, while his body is healing and taking a long nap, who knows what his spirit is getting up to?
Phenomena like "out of body experiences" and "astral projection" (where you can make your spirit leave your body and explore around) have been talked about for a long time and some people even claim that on the 'astral plane/astral realm' there are things you can learn, people you can meet, etc.
I won't go too far into this as we're not in the religion thread, but what if Arthur has been astral projecting for the centuries since his 'death' - learning more from higher evolved beings on the astral plane, putting his past to rest regarding Lancelot's affair with his wife and everything surrounding Mordred, maybe meeting Merlin on the plane and continuing to learn from him for when both will eventually return, gaining psychic/supernatural powers from the constant projections and from what he is taught, watching the world develop and change throughout the centuries and learning what worked/what didn't, etc.
As such, when he returns in the hour of greatest need (say we take the
Camelot 3000 route and claim Earth is been invaded by aliens who have wiped out the government and the monarchy), he would be smarter, wiser and more powerful than before - maybe initially joining humanity's resistance as a soldier before eventually revealing who he is and leading humanity to victory before taking his place as the new ruler to rebuild Britain and bring peace.
It's an outlandish idea, but the original stories were pretty 'Wiley Coyote' at times as well.
