God of Carnage officially opens March 25 following previews that begin March 7. The run will precede Fiennes' appearance at the National Theatre in a production of Oedipus, directed by Jonathan Kent later in this year.
Like Reza's Art, The God of Carnage will be directed by Matthew Warchus with a translation by Christopher Hampton. Producers include David Pugh and Daffyd Rogers.
Carnage, according to press notes, "tells of what happens when two sets of parents meet up to deal with the unruly behaviour of their children. A calm and rational debate between grown-ups about the need to teach kids how to behave properly? Or a hysterical night of name-calling, tantrums and tears before bedtime? Boys will be boys... but the adults are usually worse... much worse..."
Stott was in the original cast of Reza's hugely successful play Art, with Albert Finney and Tom Courtenay. Stott's previous West End performance was with Richard Griffiths and John Hurt in Heroes, by another French writer Gerald Sibleyras.
Greig is best known for her appearance in the television comedy "Green Wing." The actress won an Olivier Award for her Beatrice in the RSC's production of Much Ado About Nothing.
Reza's other credits include Life X 3 and Conversations After a Burial.
