Mithrandir, I love your idea of using the Yoda line from the new TCW episode.
And what's even better - is that the line is almost music-free in the actual episode. Might make it really easy to use.

I'm just afraid there won't be enough material to make Obi-Wan seem like he actually wants to bring Anakin back. As it is, I've slapped together a hodgepodge of lines from the EPIII video game (where Obi-Wan actually talks like he wants to help Anakin). Maybe I can kidnap Ewan McGregor and get him to record new lines for me, haha.

Little update:
Work on the prequels will come to a VERY slow crawl in the coming months.
Two reasons:

-I am going to be in Japan next year, and will only be able to do basic editing.

-I am working on a short film. It'd be awesome if everybody could back me on kickstarter:

Some of the budget is for some super-awesome software that I'll have afterward to make my Star Wars edits even better! So... there's some extra incentive, haha.
