For the film industry, the Disney hit Frozen marked a milestone. Not only was it co-directed by a woman, Jennifer Lee, it has also become the highest-grossing animated film of all time.
Yet Hollywood itself is frozen, stuck in a time warp where men still direct more than nine out of 10 films.
The situation is no better in Britain, prompting one culture magazine to launch an initiative to encourage more women to make films.
Dazed Vision, the new video arm of Jefferson Hack's Dazed & Confused media operation, is asking some of the industry's biggest names, including Jane Campion and Dame Helen Mirren, to choose their favourite young female directors to make a film - from an arts short to a music video or a piece of fiction - to show on its website.
New Zealander Campion, best known for The Piano (1993), has picked the first film-maker, Anahita Ghazvinizadeh, though she has selected something the Iranian-born director has already made.
