CANNES - In a year dominated by the #MeToo movement, the Cannes film festival - which started Tuesday - is feeling the heat to address glaring gender imbalances in the competition for its top prize, the Palme d'Or.

But the numbers show the festival still has some way to go in the battle of the sexes.

Of the 268 filmmakers who have claimed one of Cannes' top three prizes, only 11 - or four percent - have been women.

New Zealand's Jane Campion remains the only female director to have received the highest accolade, the Palme d'Or, awarded for her masterpiece "The Piano" in 1993.

Iranian prodigy Samira Makhmalbaf snagged the prestigious Jury Prize twice, first for her 2000 breakthrough feature "Blackboards" and again three years later for "At Five in the Afternoon".

The last major prize winner was Italian director Alice Rohrwacher, who took home the Grand Prix for "The Wonders" in 2014. She's back in the running this year with "Happy as Lazzaro".

Women have made up barely 3.5 percent of the best director and best screenplay winners over the past seven decades.

Only four of the 111 winners have been female - and two of them were last year when Sofia Coppola became only the second woman to secure the best director trophy with her American Civil War drama "The Beguiled".

Meanwhile, Briton Lynne Ramsay's "A Beautiful Day" scored best screenplay.

If only one woman has won the Palme d'Or it is also because very few of them ever get nominated.

Since 1946, only 84 of the 1,790 directors whose films has been shown in competition at Cannes have been women - in other words, less than one in 20.

The latest edition doesn't buck the trend, with just three female directors among the 21 main competition contenders.

This is still better than the 2010 and 2012 festival editions, which featured all-male lineups.

While Cannes organizers acknowledge the gender inequality, they insist this merely reflects the under representation of women directors in the cinema industry as a whole. - AFP
