The director of the new X-Men movie is inventing his own character to, what else?, add a large dose of sex. Link. Excerpt:
Brett Ratner is spicing up the new X-Men 3 movie with the addition of his very own fantasy - a sex siren mutant who seduces her opponents rather than battles them. . . A source tells Pagesix.com the mutant will be, "An unbelievably hot and sexy hooker. Her super power is that she secretes a pheromone that helps her to seduce men. She can seduce anyone."
Sounds lame, but no matter: just make sure the actress is attractive, and folks will flock. The director might be a moral moron, but he presumably knows his business. He probably also knows that sex can cover up for mediocrity. If he botches the movie, fewer people will notice if they're caught up in the sex siren's good looks. Sex is a distraction that allows flaws to go unnoticed.
