More comments on the set report (spoilers)

Carol earlier:
> <snip> She's supposed to be beautiful. That's part of the reason
that her damsel-in-distress appeal works: she's appealing to every
chivalric instinct that Snape--Slytherin though he is--possesses. The
other reasons, of course, are that snape genuinely cares about Draco
and he's already promised Dumbledore that he'll "do the deed" if he
has to. <snip>

Carol again:
My turn to reply to my own post. Funny how things make sense as you
type them but are confusing when you see them onlist!

I didn't mean to imply that Narcissa knows anything about Snape's
promise to DD. Of course, she doesn't. I meant that Snape's other
reasons combine with Narcissa's distress to make her appeal effective.

Carol earlier:
> As for Bellatrix's costumes, she's supposed to be wearing DE robes
in the MoM battle in OoP, but she wanted to look vampy (as well as
completely demented). I doubt that she'll vamp it up for Snape, whom
she doesn't like, and, oh, I hope that Rickman!Snape gets to speak the
sardonic lines aimed at her and Wormtail that he has in the book, 
accompanied by suitable curls of the upper lip. ("But we're not
counting vermin, are we?") <sigh>

Carol again:
My apologies for the ambiguous pronouns in this paragraph. Obviously,
the "she" who wanted to look vampy is not Bellatrix Lestrange but the
actress who plays her, Helena Bonham-Carter. All of the other "she's"
apply to Bellatrix herself. Book!Bellatrix wears DE robes in the
battle and presumably ordinary witch robes the rest of the time. I
don't know how film!Bellatrix will dress in HBP, but since she's not
out to seduce Snape, maybe she'll be slightly more covered up than she
was in the MoM battle scene.

Carol, who hates the uncanonical costuming in the later films (PoA
onward), which is much too Mugglish all around, thanks to Alfonso Cuaron
