Milk is a 2008 American biographical film based on the life of gay rights activist and politician Harvey Milk, who was the first openly gay person to be elected to public office in California, as a member of the San Francisco Board of Supervisors. Directed by Gus Van Sant and written by Dustin Lance Black, the film stars Sean Penn as Milk and Josh Brolin as Dan White, a city supervisor who assassinated Milk. The film was released to much acclaim and earned numerous accolades from film critics and guilds. Ultimately, it received eight Academy Award nominations, including Best Picture, winning two for Best Actor in a Leading Role for Penn and Best Original Screenplay for Black. Milk begins on Harvey Milk's 40th birthday (in 1970), when he was living in New York City and had not yet settled in San Francisco. It chronicles his foray into city politics, and the various battles he waged in the Castro neighborhood as well as throughout the city, and political campaigns to limit the rights of gay people in 1977 and 1978 run by Anita Bryant and John Briggs. His romantic and political relationships are also addressed, as is his tenuous affiliation with troubled Supervisor Dan White; the film ends with White's double homicide of Milk and Mayor George Moscone. The film's release was tied to the 2008 California voter referendum on gay marriage, Proposition 8, when it made its premiere at the Castro Theatre two weeks before election day.
