Thunderheart is a 1992 American Neo-Western mystery film, directed by Michael Apted from an original screenplay by John Fusco. The film is a loosely based fictional portrayal of events relating to the Wounded Knee incident in 1973, when followers of the American Indian Movement seized the South Dakota town of Wounded Knee in protest against federal government policy regarding Native Americans. Incorporated in the plot is the character of Ray Levoi, played by actor Val Kilmer, as an FBI agent with Sioux heritage investigating a homicide on a Native American reservation. Sam Shepard, Graham Greene, Fred Ward and Sheila Tousey star in principal supporting roles. Also in 1992, Apted had previously directed a documentary surrounding a Native American activist episode involving the murder of FBI agents titled Incident at Oglala. The documentary depicts the indictment of activist Leonard Peltier during a 1975 shootout on the Pine Ridge Indian Reservation.
