Animal Kingdom star Ben Mendelsohn has joined the cast of Coco Before Chanel helmer Anne Fontaine’s English-language directorial debut. Naomi Watts and Robin Wright topline the drama which has been going by the name The Grandmothers, but which is now expected to get a title change. Gaumont’s Cécile Gaget also confirms to me that Sophie Lowe of Aussie TV hit The Slap and veteran actor Gary Sweet have boarded the picture with Animal Kingdom co-star James Frecheville and Twilight: Eclipse‘s Xavier Samuel.
