Most young female actresses today are very petite, and it's hard to find the husky, busty lasses of Meyer's era. However, on one of my soaps, "One Life To Live" is Melissa Archer who plays Natalie Buchanan. She absolutely fits the model of a Meyer "star."
Britney would be better suited to play the annoying kidnap victim.
In the original film, none of the characters were anyone the viewer could easily side with.
The girl is a victim of circumstance but not a cheerable character. The others (the girl gang and the family they meet up with) are evil and self-serving.
