"Twilight" of their careers?

The fourth "Twilight" film, "Breaking Dawn," will be split into two movies, the better to maximize profits — and, some of its stars figure, maximize salary. And by "stars," we don't mean Kristen Stewart and Robert Pattinson. Supporting players Ashley Greene and Kellan Lutz have banded together to demand $4 million apiece for each of the two movies, as opposed to the reported $1 million or so they've been offered. Do they recall what happened to Rachelle LaFevre, whose hardball tactics got her dropped from "Eclipse" in favor of Bryce Dallas Howard?
