Tamsin Greig is Malvolia in a new twist on Shakespeare’s classic comedy of mistaken identity. A ship is wrecked on the rocks. Viola is washed ashore but her twin brother Sebastian is lost. Determined to survive on her own, she steps out to explore a new land. So begins a whirlwind of mistaken identities. Where music is the food of love, and nobody is quite what they seem, anything proves possible. Simon Godwin (NT Live: Man and Superman, RSC’s Hamlet) directs this joyous new production.
