The Atlantic Online ran an article a while back about superhero movies; specifically, about applying movie glamour to superhero concepts and characters. It's gone now, except for subscribers, but The Comics Reporter quoted this bit of it before it disappeared:
"Glamour is an imaginative process that creates a specific, emotional response: a sharp mixture of projection, longing, admiration, and aspiration. It evokes an audience's hopes and dreams and makes them seem attainable, all the while maintaining enough distance to sustain the fantasy. The elements that create glamour are not specific styles -- bias-cut gowns or lacquered furniture -- but more general qualities: grace, mystery, transcendence."
I'm still mulling over exactly how to apply this to my writing, but I think that part of it's allure is that it's a nebulous concept and difficult to apply. If I can figure out how to do it though... oh, baby.
