Respectable playing by actress Stefania Rocca is almost the only reason to watch “Rosa and Cornelia,” an overheated, borderline silly costumer about a countess and a country girl who spat and bond while going through pregnancy together. Commercial chances outside Italy look stillborn.
Cornelia (Chiara Muti), a mid-18th-century Venetian countess about to be married, is locked up by her parents in their country home to hide the fact that she’s preggers from a secret fling. Rosa (Rocca), a feisty peasant girl, is hired as a companion; she happens to be pregnant as well. Socially worlds apart, the two femmes eventually find common ground — and then the family’s dastardly plan, overseen by Cornelia’s wet-nurse (veteran Athina Cenci), clicks in. The elaborate plot makes no sense at all, and relationships and dialogue are thoroughly theatrical (it’s based on a play by Remo Binosi). Direction is uninflected and lensing flat.
