Johnny Depp's acclaimed cinematic stab (ahem) at Mr. Sweeney Todd, the Demon Barber of Fleet Street, has refreshed our memories on this tale of greed, revenge, and culinary cannibalism. But in this cunning stage revival, John Doyle's adroit direction blurs the line between cast and orchestra: here, ten cast members accompany each other instrumentally while simultaneously playing their character roles. The effect is sublimely terrifying, as Doyle's stylized, deconstructed staging streamlines the bloody musical into a taut and frightening theatrical machine.
