Tonight TV: The horrific story of Britain’s largest mass poisoning | television

Toxic water

9pm on BBC Two
“Before I die, I want this truth to come out.” Carol White was the victim of what this film claims was the largest mass poisoning in British history – the 1988 water contamination in North Cornwall. She remembers that her water is the color of bathroom cleaner. Numerous complaints were made (“Our daughter’s hair turned green and stuck like glue,” says one phone recording) but the authorities – some speaking here, including the former chief operating officer of South West Water – insisted the water was safe. Despite claims that aluminum is the cause of Alzheimer’s disease, there has been no completely independent public investigation. Maybe this could change that. Holly Richardson

Come on, come on (Mike Mills, 2021), 2am on Channel 4
A film that slowly digs its emotional claws into you, Mike Mills’ tender black-and-white drama is blessed with a terrific performance from Joaquin Phoenix as radio producer Johnny and Woody Norman as his young nephew Jesse. They are brought together when Jesse’s mother, Viv (the always sympathetic Gaby Hoffman), suddenly has to leave to care for his bipolar father. There’s plenty of humor to be extracted from the nine-year-old’s imaginative direct line of questioning, while Johnny uses his microphone as a private diary to reflect on his inadequate parenting skills and his strained relationship with his sister.
