Gosford Park is a 2001 satirical black comedy mystery film directed by Robert Altman and written by Julian Fellowes. It was influenced by Jean Renoir's French classic, La Règle du jeu (The Rules of the Game)
The story follows a party of wealthy Britons plus an American producer, and their servants, who gather for a shooting weekend at Gosford Park, an English country house. A murder occurs after a dinner party, and the film goes on to present the subsequent investigation from the servants' and guests' perspectives.
Development on Gosford Park began in 1999, when Bob Balaban asked Altman if they could develop a film together. Balaban suggested an Agatha Christie-style whodunit and introduced Altman to Julian Fellowes, with whom Balaban had been working on a different project.
The film went into production in March 2001, and began filming at Shepperton Studios with a production budget of $19.8 million.
Gosford Park premiered on 7 November 2001 at the London Film Festival, and was released in January 2002 by USA Films and in February 2002 in the United Kingdom.
The film was successful at the box office, grossing over $87 million in cinemas worldwide and was nominated for seven Academy Awards, including Best Picture, Best Director for Altman and Best Supporting Actress for both Helen Mirren and Meggie Smith, and won Best Original Screenplay for Julian Fellowes; it was also nominated for nine British Academy Film Awards.
The TV series Downton Abbey written and created by Julian Fellowes was originally planned as a spin-off of Gosford Park, but instead was developed as a standalone property inspired by the film, and set earlier in the 20th century.
