I just noticed something while watching the original ESB, and I didn't think of it until now, but the original Boba Fett voice sounds like a well to do guy trying to sound intimidating. It's kinda weird, but it's like Jason Wingreen is trying to hard, while Temura Morrison just talks naturally. If someone would just show me the two clips with different voices, I hate to say it but I'd prefer the voice of Temura from the SE. (?)
Oh well, maybe that's just me.
