James Cameron-Wilson looks UK cinema box office, which has declined even further than the previous week's dreadful level. But new films are being released and he was hugely moved by the documentary I Am Greta, which was fortunate to film the Swedish schoolgirl at the start of her protest that was felt around the world. Available at cinemas and on Netflix is the recommended Aaron Sorkin's The Trial of the Chicago Seven, with the main roles all taken by Brits. And James also reviews favourably the British film Lynn + Lucy.
