Joining the star, who played Sir Humphrey Appleby in the 2010 CFT production of Yes, Prime Minister and its West End transfer, are Keith Baxter, Michael Feast, William Gaunt and Joe McGann. Lizzie McInnerny will be making her Chichester debut in the role of Betty Dullfoot.
Originally written for television and screened in 1979, the play is set on a summer's day during the Second World War. It concerns a group of seven-year-olds (played by adult actors) whose innocent play becomes tinged with darkness as the children begin to turn against one other.
The cast includes Gary Beadle, who is best known for playing the character of Paul Trueman in EastEnders between 2001 and 2004. Also featured are Ryan Early, Leila Farzad, Richard Frame, Gregory Gudgeon, Daniel Rabin and Laura Rogers.
