The movie star.

Ginger was the popular, beautiful girl who pretty much got her way prior to being shipwreaked. She loved the power she got from being the center of attention. Being on a deserted island with six other less attractive people didn't stop her from getting what she desires. Ginger represented the sin of Lust. Like Mr. Howell, she desired power; power was her weakness. She would use her looks and sex appeal on the other Castaways, as well as the various visitors, to get what she wanted. Was this power enough to get them off the Island? I don't think do. She only used power for her own selfish needs, and not for the benefits of their little Island society
