I could have swore I was in the Episode III forum...
Try here: Episodes IV-VI
no i think its just because of recording equipment. Cause in ANH it sounds like its higher pitched and like he's yelling. ESB he was lower, louder and carried out his vowels more "wookieeee to my ship." and then finally ROTJ which was the best voice and suit, it was just loud clear, deep, and menacing.maybe he was just experimenting with his voice or maybe it was due in part to upgraded sound equipment, but either way ep6 was the best and i hope he does it in ROTS.
Yeah, in addition to his appearance, I noticed that Vader's voice differed in EACH of the movies.
In Ep. IV, Vader's voice wasn't as refined or regal sounding as it was in V and VI. Vader's voice showed much more emotion and anger ("Tear this ship apart!"😉 than in the following episodes.
In Ep. V, Vader's voice was the best IMO. I noticed that his voice wavered alot (ex. "Well, Calrissiaaaan, did he survive?" and "Take the Princess and the wookieee to my ship" as stated above), but was also quiet and succinct yet powerful at the same time: "Don't fail me again.", "Apology accepted, Captain Needa." Vader's voice was much more cold, calm and collected than in Ep. IV and didn't show as much emotion.
In Ep. VI, Vader's voice was much deeper than the previous 2 episodes and didn't have the waver in his voice like in Ep. V.
Perhaps he was *Just* a villain in Episode IV and GL wanted to make him as threatening and as vile as possible.
But when it was successful enough to allow him to create sequels he decided to make him more than *just* a bad guy. He needed character. The audience needed to know he was the bad guy but not to hate him. He was toned down a little to lessen the shock when you find out that he's Luke's Dad.
He's no cuddly teddy bear but is a little less threatening then the epIV version by epVI.
