Plenty is a play by David Hare, first performed in 1978, about British post-war disillusion.
Hare's inspiration for Plenty came from the fact that 75 per cent of the women engaged in wartime SOE operations divorced in the immediate post-war years; the title is derived from the idea that the post-war era would be a time of "plenty", which proved untrue for most of England.
Directed by the playwright, Plenty premiered in the West End at the Lyttelton Theatre on 7 April 1978, featuring Kate Nelligan as "Susan", the protagonist. It was nominated for the Olivier Award as Play of the Year and Nelligan as Best Actress in a New Play, losing to Whose Life is it Anyway? and Joan Plowright in Filumena.
The play premiered Off-Broadway on 21 October 1982, at the Public Theater, where it ran for 45 performances. Directed by Hare, Nelligan reprised the role of Susan, supported by Kelsey Grammer and Dominic Chianese. The play opened on Broadway (directed by Hare) on 6 January 1983 at the Plymouth Theatre, running for 92 performances and eleven previews. Nelligan was joined by Edward Herrmann, Daniel Gerroll, Madeleine Potter and George N. Martin.
In 1985, Hare's film adaptation was directed by Fred Schepisi, with Meryl Streep as Susan, and Charles Dance, Tracey Ullman, John Gielgud, Sting, Ian McKellen, and Sam Neill in supporting roles. Ullman and Gielgud were nominated for BAFTA Awards, and Gielgud was named Best Supporting Actor by the Los Angeles Film Critics Association and the National Society of Film Critics.
