The Female Heroine : the Portrayal of Female Empowerment and Feminist Representations of Film

Over time, the way that female heroines are portrayed in movies has changed dramatically. Gone are the days when these characters are weak, helpless damsels in distress; instead, they are strong, independent women who identify with feminist principles.

We can examine the varied ways that female heroes are portrayed and how they influence viewers and society as a […]
