The Untouchables is a 1987 American crime film directed by Brian De Palma, produced by Art Linson, and written by David Mamet. The film is loosely based on the book of the same name (1957) and the real-life events it was based on, but most of its plot is fictionalized. The film stars Kevin Costner, Charles Martin Smith, Andy García, Robert De Niro (third collaboration between De Palma and De Niro, following 1968's Greetings and 1970's Hi, Mom!), and Sean Connery, and follows Eliot Ness (Costner) as he forms the Untouchables team to bring Al Capone (De Niro) to justice during Prohibition. The Grammy Award–nominated score was composed by Ennio Morricone and features period music by Duke Ellington.
