Plus a powerful photographic series by Sergey Ponomarev looking at Syrian residents and refugees. Syria: A conflict explored at Imperial War Museum, until 3 September, free ★★★★☆ Tabish Khan
Theatre review: Canada dry
Jordan Tannahill's taut, 70 minute darkly comic real-life social drama Late Company draws two Toronto couples into 'God of Carnage' country as they attempt closure over the suicide of Joel, bullied at high school for homosexuality, and confront the teenager who may have been his antagonist. It's not nearly so simple as that, and you may switch sides many times during the night, but in real time on an authentic set. The cast is superb, with special mention going to Lucy Robinson's glaciated middle class sculptress turning feral in defence of her lost son, and David Leopold's brooding, near-mute Curtis intimating all his thoughts with body language. Read more here. Late Company, Finborough Theatre, 118 Finborough Road, Earl's Court, SW10 9ED, £14-18, until 20 May ★★★★☆ [Tuesday-Saturday] Johnny Fox
