Ok, so Two Mothers is actually based on a short story called The Grandmothers by Doris Lessing, not an SNL digital short. Naomi Watts and Robin Wright play best friends in Australia who fall in love with each others' sons.

The screenplay was written by Christopher Hampton, who wrote Dangerous Liaisons and more recently, the Freud/Jung drama A Dangerous Method. Apparently in the book, though, the two sons are married and have families, which obviously raises the stakes beyond the usual May/December romance. And they're grandmothers, not just in their forties.

Anne Fontaine (Coco Before Chanel) directed the sure-to-be controversial film, which will come out this summer.
