Grand MILFs

Naomi Watts, James Frecheville, Xavier Samuel and Robin Wright have joined the cast of "The Grandmothers" says Screen Daily.

An adaptation of the 2003 novella by award-winning author Doris Lessing, the story follows two childhood friends and neighbors who each fall in love with the other’s son, to the disgust of the boys’ wives.

French director Anne Fontaine ("Coco Before Chanel") helms the English-language film using a script by Christopher Hampton ("Atonement").

Production kicks off in Australia in February
