This is a technical issue. During the movie, Natalie Portman has a fairly low (deep tone) voice, either as Queen Amidala (?) or as Padme. It seems that she changes her cadence and intonation when she's playing Padme acting as the Queen, but this isn't what I'm talking about. In the Theatrical Trailer, her voice sounds distinctly higher, not in volume level, but in tone (ie: sounds more like a young girl) than in the Movie. Yet the shots, cadence and intonation in the Trailer are identical to the Movie itself. Can anybody explain this different voice tone, from a technical perspective? I have a few hypothesis: 1) The trailer is time compressed. As such, they have sped up the vocal track, and voices sound higher. Think "The Chipmunks", but to a much, much lesser degree. It would be subtle, and any time gain would, I think, be minimal. They would be better served keeping the words at regular speed and cutting down on the pauses, or starting the voice track early (before lips move) and have it run a little long. 2) The voice track, like the film stock itself, had yet to be finalized. I'm a little shaky on this one, but it seems that trailers aren't necessarily the final color-corrected film that the final cut of the Movie gets. If (big if) this is true there may be a corollary with the sound, and the same track in it's final form could sound significantly different, and deeper. This seems unlikely, though, as Darth Maul's voice in the same Theatrical Trailer sounds identical (and just as deep and bass heavy) as the movie itself. 3) There difference lies in how my system produces DD 5.1, as the movie is, and DD 2.1, which is what I believe the Trailer is (Note: my receiver has lights that represent each audio channel received; this is what the DD 2.1 is based on.) This could be true, but the Darth Maul example (in 2 above) would seem to disprove it. 4) Lucas (or somebody else) was displeased with Portman's vocals during production, and had her loop her lines afterwards, in a controlled environment, where she (or the mixer) could emphasize the depth of her voice. Possible, but as the cadence and intonation of the line from the Trailer versus the Movie seem identical, I have some doubt. 5) This one seems the most likely to me. Lucas decided after the fact, and after the trailer had been cut, to digitally "enhance" Portman's lines to give them more gravity. The timing would be critical, as they "correction" would have to have taken place after the trailer was cut. This certainly seems possible, and kind of dovetails with (2) above, but whereas (2) would be in the normal evolution of the Movie, (5) has the hallmarks of digital tampering. Anyway, those are my long-winded theories. If you made it this far I'd really like to hear what you think, and even better, what you know. Thanks.
