Joining the previously announced Robert Lindsay, who is playing Henry II, and Joanna Lumley, who is playing Eleanor of Aquitane, are Tom Bateman (Richard), Sonya Cassidy (Alais), Joseph Drake (John), Rory Fleck-Byrne (Philip) and James Norton (Geoffrey).

In the play, a family Christmas becomes a family at war. Henry II, not so young as he was, invites his estranged wife Eleanor of Aquitane, and his three sons, Richard, Geoffrey and John, to spend the festive season with him, his mistress Princess Alais, and her brother, the young King Philip of France. Will Henry name who is to be his successor as King of England? According to press materials, their "yuletide celebration turns into a combat zone of deceit, betrayal, bitter power games and scabrous wit."

Bateman, who graduated from LAMDA in summer 2011, made his professional debut as Claudio in Josie Rourke's recent West End production of Much Ado About Nothing.

Cassidy has previously worked with Trevor Nunn in his Old Vic production of Inherit the Wind. Other stage credits include The Prince of Homburg at the Donmar Warehouse.

Drake was recently seen in The Deep Blue Sea and Rattigan's Nijinsky at Chichester Festival Theatre. Other credits include Vernon God Little at the Young Vic. Fleck-Byrne appeared at Liverpool Playhouse in Janet Suzman's production of Antony and Cleopatra, and has also appeared in Cause Célèbre at the Old Vic and Disco Pigs at the Young Vic.

Norton made his professional West End debut as Stanhope in Journey’s End at the Duke of York’s Theatre. Other theatre credits include That Face at Sheffield Crucible and Posh at the Royal Court.

Produced by the Theatre Royal Haymarket Company, the production has set and costume designs by Stephen Brimson Lewis, music by Steven Edis, sound by Paul Groothuis and video design by Ian William Galloway.
