Guyana Crime of the Century also known as Guyana Cult of the Damned is a 1979 exploitation horror film written and directed by Ren 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 OBrien Barry rather than Leo Ryan.
Most notably, the Johnsontown membership is largely cast with white actors, while in reality, and at its height, the majority of Peoples Temple members were AfricanAmerican.Moreover, the film depicts Susan Ames the fictionalized version of Peoples Temple loyalist Sharon Amos, as played by Yvonne DeCarlo being murdered, along with her children by a shadowy, knifewielding man. In reality, Sharon Amosa hardcore supporter of Jim Jones stationed in nearby Georgetownfollowed the orders of Jones for his followers to die on November 18, 1978. Amos reportedly took a kitchen butcher knife and slit the throats of her two youngest children Christa, ageand Martin, age 10, then asked her eldest daughter Liane ageto kill her with the knife, thus leaving Liane to kill herself. ........
