James Cameron-Wilson looks at a UK box office that continues to thrive, with takings up massively on 2017. He reviews the week's new films, including BlacKkKlansman, The Spy Who Dumped Me and The Children Act. Liking the latter enormously, he wonders why it is showing in so few screens despite having the second-best per screen average. He also recommends, on home release, In The Fade, starring Diane Kruger.
