Most comic book characters with enough public cachet to make it to the big screen have been through a few phases. Wonder Woman is no exception. As conceived in the early 1940's she was an icon to be held up as a role model for a different kind of woman who was emerging. Creator William Marston wrote (via Wikipedia) "Not even girls want to be girls so long as our feminine archetype lacks force, strength, and power. Not wanting to be girls, they don't want to be tender, submissive, peace-loving as good women are. Women's strong qualities have become despised because of their weakness. The obvious remedy is to create a feminine character with all the strength of Superman plus all the allure of a good and beautiful woman."
