Pop-Ed: Mae West once said, "There are no good girls gone wrong. Just bad girls found out." I'm left contemplating those words as I watch Angelina Jolie, whose role unfolds as the ultimate femme fatale ("deadly woman" in French) over the course of her new action thriller, 'Salt.'

With roots in the hothouse eroticism of film noir, today's sinister seductress is a hardcore action heroine. No longer packing an automatic pistol in her garter while balancing a martini seductively in one hand, the modern femme fatale serves up her balm of praise with a heavy dose of artillery and explosives. Duplicitous to the core, she is never what she appears to be. Read on for Gina's take on how Jolie raises the bar for future femme fatales.
