Love Fried Green Tomatoes. Great movie. The obvious one that comes to mind is Thelma and Louise, which get sme every time. A less obvious one is The DEscent which is a horror movie, but centred around these really strong women, so I was pleasantly surprised.

Like Heather said this could turn o ut to be a looooong list so maybe I will have a think about the rest of them and come up with some ultimate favourites
