‘Lord of the Flies’ VS ‘Heathers’…

A few years back some male film makers were going to try and do a female remake of ‘Lord of the Flies’ but couldn’t sell it because all the backers thought that if a group of girls got stranded on a deserted island with no boys they wouldn’t try to compete to the death. They would just end up cooperating because without men or the patriarchy to influence women, everything would be fine… I thought about ‘Heathers’ and realized that maybe women just compete in different ways but perhaps even that wouldn’t be a factor anymore if girls were in a life or death survival scenario… Thoughts?
