The red carpet at any film festival is known for star power and fashion, but when 82 women walked arm in arm down the red carpet at Cannes last month, it became a place for politics, too.

The march highlighted the lack of women represented at cinema's most esteemed festival, and it comes at a time when the industry as a whole is being asked to provide equal treatment and inclusion for women and other groups that have been marginalized.

Such explicit statements may not have been made at the smaller festivals and conferences as of yet, but there's no doubt such events will face increasing scrutiny.
