In film, women are typically the objects, rather than the possessions, of gaze because the control of the camera (and thus the gaze) comes from factors such as the assumption of hetrosexual men as the default target audience for most film genres. Women are the bearer of meaning, not the maker meaning.
Superheroine's are often young, pretty, curvaceous, have limited powers and wear skimpy outfits. They are stereotypically drawn by men and designed to capture the male gaze. When women are featured in films they are normally sexualised, this being the fact that sex sells!
Superheroes are sterotypically 'ripped', stronger than women and genrally have a troubled past where there has been a tragic event for example Spiderman. Spidermans parents were murdered when he was young and because of the research that his late father did he became spiderman and helped to save the world.
