There are two ratios – one overused and unhelpful, one under-appreciated and telling. The first is the ratio of men to women in film-making (huge). The second is the ratio of women film-makers to good women film-makers (in relative terms, tiny). Today in 2014, women arguably lead the world in quality film-making (Lucrecia Martel, Claire Denis, Joanna Hogg) but if we look back in time we see that there have always been great women directors – Riefenstahl, Dulac, Deren, Varda, Huillet, Duras, Campion, the list goes on. They distinguish themselves not just because they bring women’s lives and desires to the screen, but regrettably because too often male filmmakers don’t. I’ve pared it right down to thirty to highlight the phenomenal breadth and richness of the contribution women directors have quietly made to Film history.
