In Sally Potter’s new coal-black comedy The Party, Janet (Kristin Scott Thomas) is hosting an intimate gathering of friends in her London home to celebrate her political ascension, while her husband, Bill (Timothy Spall), seems preoccupied. Janet’s acerbic best friend, April (Patricia Clarkson) arrives and others follow, some with their own dramatic news to share, but an announcement by Bill provokes a series of revelations that gradually unravel the sophisticated soirée, and a night that began with champagne may end in violence. Also starring Emily Mortimer, Cillian Murphy and Bruno Ganz.
