Actually, Charly Sheen is a " low to mid level" sex, alcohol and dope fiend by Hollywood standards. There are those here who would absolutely die if their escapades became public like Charly's has. Quite a few major stars that I know of would shoot themselves and their are more women stars that fit the category than men. FYI.
But at what point do those issues stop being the individual’s problem and becomes the employer’s problem? Hollywood depends so heavily on image that I’m surprised it’s tolerated much at all.
