Who?
Does that apply to the actress or her character?
While perhaps unknown to some of us, she has actually worked fairly steadily in films since 1995, when she had an uncredited role as one of Eli's followers in "Children of the Corn : Urban Harvest."
That may change, as she is not only appearing in the sequel to "Mad Max : Fury Road" "Mad Max : the Wasteland," but also "The Last Face," which is just wrapping up production, the sequel to "Snow White and the Huntsman" "The Huntsman," which should be out next year in 2016, and in which she plays the same character, Ravenna, which she played in the original film, and she voices a character in the animated "Kubo and Two Songs," which should also be out in 2016.
A South African, she is related to South African military figure Danie Theron, and get her out of her makeup for "Mad Max : Fury Road," and I think she is actually not that bad looking.
As for myself, the most attractive actresses are not those that are most physically attractive, but whose attractiveness comes from inside the actress. Such as . . .
Sylvia Kristel in "Private Lessons."
Carla Gravina in "The Tempter"
Amanda Donohoe in "Lair of the White Worm"
etc.
And we shall see what we shall see.
