Wicked Little Letters: Thea Sharrock’s lighthearted film is inspired by a true story, preposterous as fictional writers can seldomly be; an Irish woman is accused by her church-going spinster neighbour of writing, well, wicked little letters, but the process was not what it was supposed to be because of who she was and how she acted. The film touches on many thorny issues, not the least of them the way women in the UK were treated before the suffragette movement. This film’s greatest pleasure is to watch the two great actresses play their role: Olivia Colman as the conservative and repressed spinster, and Jessie Buckley as her antithesis, the potty-mouthed and lively young woman. As the policewoman who decides to dig deeper despite orders to the contrary, Anjana Vasan is pretty good as well, as is Timothy Spall, playing the uptight and dismissive father of Colman’s character. The film is cleanly made, with costume designer Charlotte Walter creating appropriate and detailed garments; the musical score, by composer Isobel Waller-Bridge, helps to keep the tone light.
