So I was rereading the newly-merged Jedi clothing thread when something hit me. I've noticed before that the overall look of Obi-Wan Kenobi, and particularly his hairstyle, in the concept art dating to the rough draft of TPM... ...appears to have been based closely on Madmartigan (played by Val Kilmer) in Lucas's earlier film Willow. Both of them have long dark hair with two thin pigtails in front and a ponytail/topknot in back. Of course it's well known nowadays that the legendary Moebius, aka Jean Giraud, did some concept art for Willow back in the day. Here is his take on Madmartigan: You can see Moebius is really running here with the Japanese-influenced aesthetic that Lucas likes. The hair of this Madmartigan is quite similar to the final film's version--although Moebius seems to have included a shaven area just above the forehead, rather after the fashion of a Japanese chonmage or Manchu-dynasty Chinese men's hairstyles. But that's not the only bit of TPM character design Moebius had a hand in retroactively. Take a look at his designs for another character in Willow--the warrior woman Sorsha, who starts out as a villain and becomes Madmartigan's love interest: Moebius has Sorsha wear a white Noh mask, adorned with ornamental red patches. Now whom do we know in TPM who dresses like that? Oh, right. There's also the matter of Sorsha's hairstyle in the second piece of concept art above. In the rightmost drawing there, she has a long blonde ponytail on the back of her head; the rest of her head is shaven. Compare bounty hunter Aurra Sing from TPM: Aurra also has Luke's long rifle from Ralph McQuarrie's ANH concept art, so it's safe to say she's been put together from various pre-existing unused designs. As for Sorsha in the final cut of Willow, she didn't end up with the Aurra Sing hair, or even blonde hair: the shooting script specifically calls for her to be a redhead, and that's what got filmed.
