Lizzie Clachan has turned the Young Vic into a planetarium for Joe Wright's production of Brecht's Life of Galileo, one of the most visually stunning and inventive shows on the London stage right now. The set is in the round, with a central pit where some of the audience sit on cushions, with the actors mingling around them. It gives the impression of a group of students in a relaxed setting, sitting around a charismatic teacher who's on a roll. The teacher is Galileo Galilei (Brendan Cowell,) the subject he's excited about the Copernican Heresy, which proposed that the Earth revolved around the Sun, and which astronomer Giordano Bruno had recently been burned at the stake for promoting. But Galileo teaches in Padua, which has a special exemption from the Inquisition's clutches and besides, having stolen credit for the invention of the telescope, he now has a tool that he can actually use to look at the stars and prove Copernicus right.
