A movie about two women who want to sleep with each other’s sons sounds like it’s either going to be something sleazy or some sort of grossout comedy, but Two Mothers is actually based on a novella by Nobel laureate Doris Lessing.

The movie sees Naomi Watts and Robin Wright as two women who’ve been friends for decades and live next to one another on an Aussie beach. However their idyllic but lonely lives get a little more complicated when the women start eyeing each others sons – Xavier Samuel and James Frecheville – with more than maternal affection.

Anne Fontaine’s film certainly looks intriguing, although whether it can handle its tricky subject matter is yet to be seen.
