I always wondered why out of a lot of Disney movies that didn’t really need sequels, that they never did one to The Sword in the Stone. They could add in more from the King Arthur/Camelot legend. Characters like Morgana/Morgan Le Fay, Morgause, Lancelot, Guinevere, etc.
But knowing Disney, they would have to change some things from the legend. They likely wouldn’t have Gwen cheat on Arthur with Lancelot, Arthur wouldn’t die, Arthur wouldn’t rape his half-sister Morgana/Morgan Le Fay resulting in the birth of their incest child that would kill Arthur, Mordred. It is Disney, after all, and there’s no way any of those protective parents would allow their children to see it. Anyway, I’ll just copy and paste what I said about the pictures from my deviantart descriptions.
For Adult Arthur, I used a lot of Phoebus, but for the face, I actually used Edward from Enchanted and I gave him a different crown from the one he had in the original movie that was too big for his head lol. I also felt like a beard would complete the look because I usually associate an adult King Arthur with a beard. I had his armor made out of gold with a Camelot symbol to contrast with Lancelot being in silver to indicate who the leader was (Though, the crown does give that away lol). I also gave him a red cape to kind of be a call back to his red squire outfit.
Gwen's design is definitely my favorite out of all of them because it's such a gorgeous design in my opinion. I couldn't decide if I'd use the face of Madellaine from The Hunchback of Notre Dame 2 or Daria from The Princess and the Pea (Which is a movie most people don't know about), so I found a way to compromise. I used the head shape of Daria (As well as her bangs) and the face of Madellaine. I also used the hair of Giselle from Enchanted. I love the way she looks in green, particularly since redheads looks wonderful in green. I always kind of imagined Gwen as a redhead for some reason and green just really seemed to suit her.
With Lancelot, I just had to make him black because (I don't know how) he seems to be portrayed by African American men quite a lot. For him I used bits and pieces of Sweet from Atlantis and James from The Princess and the Frog. I did try to make him look younger than those characters because he would be the same age as Arthur. Merlin and Archimedes have very little change in their appearances, other than that I used a different color palette to make them look like they are in a movie with better animation. No offense to anyone who likes the animation in the original Sword in the Stone but it's pretty average with a mediocre color palette, sketchy lines, unimpressive backgrounds, and some things that look either repeated in the movie or unfinished. Although, the magic that Merlin and Madam Mim do is impressive, whether it's by themselves or against each other in the wizards duel.
I drew inspiration for their designs off of the way they looked in the BBC Merlin show. I almost when with green with Morgana but I decided not to because I planned on making Guinevere a redhead and I think green looks really good on redheads. Plus purple does show her belief that the throne is rightfully hers and not her half-brother's. She also has green eyes to show her as the envious green-eyed monster. I also felt like doing another picture of them but this time doing some magic. I loved having them summoning magic with their hands, their eyes glowing the same color as their normal eye color (Green for Morgana and violet for Morgause), and Morgana's purple gem glowing as well.
