Take the wit and glamour of Old Hollywood, add in some contemporary pop and theater stars (Ugly Betty’s Vanessa Williams, Nicola Roberts from the English girl group Girls Aloud, London theater darling Rosalie Craig), and you’ve got this hit musical revival, transferring to the West End six years after it first played at London’s Donmar Warehouse. It’s again directed by Josie Rourke. —K.F.
