It wouldn’t be remotely surprising if someone cast Maggie Smith and Judi Dench and Joan Plowright and Eileen Atkins in a genteel drama about four octagenarian widows who gossip in a garden, but this one’s actually a documentary. The four actresses – all Dame Commanders of the British Empire – literally just sit there and drink tea and talk to one another about the movie business. Apparently it’s very charming. (Fun fact: Maggie Smith has never watched a single episode of Downton Abbey.) A big hit in the UK earlier this year, this one’s inexplicably screening for one evening only.
