Actually, I'm not even convinced the '2nd NO' is actually voiced by James Earl Jones. It almost sounds like that 'Qui-Gon Jin NO', they used in AotC. Anonye else got that impression after hearing it a few times? (And no, I don't like it).

Listened to the FORCECAST this week. They talked to Matt Wood who swore up and down it was James Earl Jones, but was oddly evasive about when and for what it was recorded, except that it's not new, it's from the archives.

It's easy to imagine JEJ doing 8 or 9 takes of screaming "nooooooooooo" that eventually just for variety he'd do one that was wierd and not cool. And of course that's the one LFL went with.
