You know, after a discussion I had once ona forum about whether an actor was or was not blonde I came to the conclusion that thanks to the repeated use of blnde hair dye in the media no one knows what a natural blonde looks like anymore.

I agree!

fpb, nothing in the book rules out that Narcissa dyes her hair. She could easily have had blonde hair as a child that darkened in adolescence. Adults with very pale hair are really really rare, and why would Narcissa be one of them when the rest of her family has darker hair?

Personally, I don't care. All of the Malfoy actors have bleached hair. It's hard enough to find proper actors without trying to match everyone's physical characters perfectly.

Jessica Alba as Storm was a little ... stranger. She's actually a different ethnicity than her character.
