Sandrine Bonnaire is of course a household name for anybody interested in French films, but what I didn't know until now is that she has a sister with autism. She has made a documentary about her sister, Elle s'appelle Sabine (Her name is Sabine), which is now on release in the UK and reviewed here.
Appearing with the well-known statistical pattern of London buses, here are two other French films that promise to be interesting:
Couscous (La graine et le mulet)
Les femmes de l'ombre -- about the women fighting in the Résistance. Never mind the politics, it has Sophie Marceau and Marie Gillain, that's reason enough to see it :)
