Dear God...why doesn't this surprise me?
Iain McCraig:
"It's not in the [ROTS] script anymore, but we were told that Han Solo was on Kashyyyk and that he was being raised by Chewbacca. He's such a persnickety guy later on - he always has to have the best of everything - so I thought it'd be great if when he was a kid, he was an absolute slob."
And gee, whaddyaknow, looks like originally lil' Han was supposed to help Yoda track down General Grievous. What a shocker.
Words fail me. And I don't think there are enough facepalms on the intraweb to capture adequately the sheer stupidity of this idea.
