Guyana: Crime of the Century is a 1979 exploitation horror film written and directed by René Cardona Jr.. The film, which was shot in Mexico is very loosely based on the Jonestown Massacre. It stars a number of American actors such as Stuart Whitman and Gene Barry. 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" rather than Rev. Jim Warren Jones, and the murdered Congressman is "Lee O'Brien" rather than Leo Ryan.
