The Kull warriors or similar being all in black would actually be quite symbolic against the troopers all in white.

Agreed about the animated PT. I'd happily watch an animated fan-made prequel trilogy alongside my Adywan OT. People may argue about continuity being compromised but when you think about it, you could end up with characters that actually look like young versions of Alec Guinness and Sebastian Shaw. Being animated would just be an alternate style for a different trilogy. Much of the prequels looks like a pixar movie anyway afterall.

There's an animated PT thread somewhere on here.
