The most recent incarnation of Blithe Spirit that opened this past week at the Shubert Theatre is sheer joy. The Noël Coward bon-bon stars Angela Lansbury in a “leave ‘em dead in the aisles” (if you’ll pardon the expression) role as Madame Arcati, a psychic retained to conduct a séance. Ms. Lansbury’s performance is nothing short of mesmerizing. Rounding out the cast is Rupert Everett in a spot-on Broadway debut, Christine Ebersole and Jayne Atkinson. The pace of this production is exactly what one hopes for in a production of a Noël Coward work. At the helm of this production is Michael Blakemore (Copenhagen, Democracy).
