The second feature from director Rebecca Daly and screenwriting partner Glenn Montgomery follows The Other Side Of Sleep (2011) with a further intense exploration of grief, loss and isolation. More approachable than their dreamy, elliptical debut, it is still a dour, slow-burning drama that is more likely to attract widespread festival attention
than significant theatrical suitors. The subject matter and treatment suggest some commercial parallels with Toni Colette/Jack Reynor tale Glassland. In Mammal, sensitively judged, totally committed performances from Rachel Griffiths and Barry Keoghan carry a tale that edges towards Greek tragedy in its treatment of the fragile, twisted bond between mothers and sons.
