^^ I can't wait to see those tweaked vader videos either. Sounds interesting.

In many ways the Vader of ANH was so different from ESB & ROTJ. In ANH aside from speaking faster and with a higher pitch Vader's costume is also a lot less polished and his cape is worn differently over his upper chest plate...plus you can see his eyes in many shots.

The Vader we see in the next two movies is much more HIGH polished, calm and cool and speaks in a more consistent tone.

I know part of this is the fact that Vader in ANH vs the other 2 movies was almost a different character. In ANH, GL had no clue about the father angle or many other things. Vader was mostly just a strong arm of equal power or maybe even less than Tarkin who was the real bad-ass.

ESB & ROTJ was where Vader truly stepped up and became more of fully realized 3 dimensional character.
