Festen is a British stage adaptation of the Danish film of the same name (The Celebration being the film's release title in North America). The adaptation is by English playwright David Eldridge. It was first staged in 2004 by producer Marla Rubin at the Almeida Theatre in London, and has since been staged in many countries around the world.
As in the original movie, Festen satirises the hypocrisy of a large and wealthy family by observing the events that unfold at the ancestral home during a reunion held to celebrate the oldest family member's 60th birthday.
As the time arises for birthday speeches to be made to the party's subject, one of his sons stands and asks the assembled guests to choose which of two prepared speeches he should read. The guests select one not knowing its contents, and the son declares it the "truth speech". As he begins to talk, it becomes dramatically clear that he is not praising his father but accusing him of having abused him and his sister over a period of years during their childhood. The rest of the story traces the family's turbulent battle with the truth to discover whether the son's cold rage is justified or the product of a deranged imagination.
Festen premiered at the Almeida Theatre in London and ran until 1 May 2004 before transferring to the Lyric Theatre. It was directed by Rufus Norris, designed by Ian McNeil and co-produced in the West End by Marla Rubin and Bill Kenwright. The production then went on a four-month tour throughout the UK. Festen has gone on to be produced around the world in countries including Australia, Greece, Ireland, Mexico & South Africa.
In a review of the Almeida production, The Stage noted that in the conversion from a film to a stage version, the story had "lost little of its power to shock and enthral in its transfer to the West End." A BBC London reviewer described the play as "one of the most powerful, poignant and overwhelming evenings I've ever spent in the theatre."
The West End production ran from 15 September 2004 until 9 April 2005.
The U.S. production ran at the Music Box Theatre on Broadway from 23 March until 9 April 2006.
