I've just learned a bunch of new things regarding the movies by reading your post. Like the fact that we had two actresses play Susan Bones, but when I read that part about Lavender I was like "No way!". I was wrong, you were right obviously.

Lavender ain't brown no more.

Anyway, Daphne Greengrass usually has the following looks: black hair and blue eyes, black hair and green eyes, blonde hair and blue eyes, blonde hair and green eyes.

I can't remember what she looked like in that cliche-parody "Ice Princess" though and that "Death Before Dishonor" is one of the few that has her as a redhead. Or maybe not, I've just not read too many fics with her.
