Patricia Clarkson is getting used to playing villains. If you’ve been watching Sharp Objects, the HBO thriller in 8-parts that will have its final episode this coming Sunday, you’ve seen this actress from New Orleans at her sinister best, a matriarch called Adora who is anything but adorable; her name alone exudes irony. Clarkson wears her bad side with high hauteur, an elegance and beauty that goes icy as human emotions draw near: it is impossible to turn away from her. In a new movie, The Bookshop, a lovely take by Isabel Coixet on Penelope Fitzgerald’s novel, starring Emily Mortimer, Clarkson continues in craven glamor. Bill Nighy’s character calls her behavior regarding the takeover of a bookstore repulsive. Clarkson says her acting strategy for playing hideous is to channel Glinda, the Good Witch.
