Play of the week: Chimerica, Harold Pinter Theatre, London SW1

Smart, entertaining production: Chimerica (Johan Persson)

The mystery at the centre of Lucy Kirkwood's play, transferred to the Harold Pinter Theatre after a lauded opening at the Almeida, resides in one of the most evocative photographs of the last century: that of the unidentified Tank Man in Tiananmen Square in 1989.

Kirkwood here assigns this photograph to the fictional snapper Joe Schofield, played in a whirring narrative of sleuthing and newspaper politics by Stephen Campbell Moore. In Lyndsey Turner's smart, entertaining production, the action jumps fruitfully from past Chinese history to an immersion in present-day American politics.
