Lady Bird (2017) BBC3, 9.15pm

Saoirse Ronan (above) is on great form in director Greta Gerwig’s funny, insightful coming-of-age comedy. Teenager Christine – or Lady Bird, as she prefers to be called – can’t wait to fly her California nest, but her mum (the excellent Laurie Metcalf) doesn’t think the family can afford her grand plans to go to college in New York.
