If Under the Shadow and Oscar-winner The Salesman have you intrigued by Iranian cinema, Inversion [PG] is a drama exploring the insidious pressure of family expectations, weighted against protagonist Niloofar for her femaleness. The title refers to the smog over Tehran: this threatens the health of our heroine's mother, and she sees and pulls away from the demands of her brother, a doctor and an old boyfriend. Sahar Dowlatshahi is the magnificent lead.
