Christopher Hitchens spent four decades as a journalist, essayist, and public debater, and this film assembles his life from archival footage, television appearances, and interviews with people who knew him, including friends, colleagues, and family. It traces his path from British socialist journalism to Vanity Fair columnist and author of God Is Not Great, the book that made him one of the most visible atheist voices of the 2000s. Footage of his public debates, including sparring matches with religious apologists and his early support for the Iraq War, shows the combative style that made him as many enemies as admirers. Interview subjects revisit his friendships and fallings-out, his heavy drinking, and his final years writing about his own terminal cancer diagnosis with the same unsparing voice he used on everyone else. The film stays close to his own words, letting the archive make the case for why he mattered.
