Guyana: Crime of the Century (also known as Guyana: Cult of the Damned) is a 1979 Mexican exploitation docudrama film written and directed by René Cardona Jr.. The film, which was shot in Mexico, is based on the Jonestown Massacre. It stars a number of American actors such as Stuart Whitman, Gene Barry and Joseph Cotten. The names of central characters are slightly tweaked from the historical ones: the film is set in "Johnsontown" rather than Jonestown, the cult is led by "Reverend James Johnson" (Whitman) rather than Rev. Jim Warren Jones, and the murdered Congressman is "Lee O'Brien" (Barry) rather than Leo Ryan.
