Killers of the Flower Moon is Martin Scorsese's sweeping 2023 epic based on David Grann's bestselling non-fiction book of the same name. Set in 1920s Oklahoma, the film chronicles the Osage Indian Nation Murders, a horrifying series of killings targeting wealthy Osage people after oil was discovered on their land. With Leonardo DiCaprio and Robert De Niro headlining alongside Lily Gladstone's Oscar-nominated performance, it is a haunting American tragedy.

The film follows Ernest Burkhart (DiCaprio), a World War I veteran who comes to work for his uncle William Hale (De Niro) in Osage County. Ernest marries Mollie Kyle (Gladstone), an Osage woman whose family begins to die under mysterious circumstances. What unfolds is a methodical exposé of greed, racism, and systemic betrayal, as the newly formed FBI under J. Edgar Hoover begins investigating what became one of the most significant murder conspiracies in American history.

Running at approximately three and a half hours, Killers of the Flower Moon is a monumental work of cinema that insists on its audience confronting the ugliest chapters of American history. The film was celebrated for its performances, particularly Lily Gladstone's groundbreaking portrayal of Mollie, and earned numerous awards nominations. It is both a mystery thriller and a profound meditation on guilt, complicity, and the erasure of Indigenous peoples.
