My Grandparents’ War: Keira Knightley
Channel 4, 9pm
The documentary series that explores the wartime stories of famous people’s grandparents plays host to Hollywood superstar Keira Knightley. She is an endearing presenter, and her maternal grandparents, Mac and Jan Macdonald, prove a charming romance amid the horrors of the Second World War. It’s just a shame the whole thing is undercut with big clunking references to Myheritage.com, which sponsors the series.
