Wearing significant prosthetics to add weight to both his face and stomach, Peters gives a scary turn as crazed cult leader Jim Jones, who pulled off one of the biggest mass murders in history. The ordained pastor was the founder of The People's Temple and initially gained followers by spreading messages of social change and racial equality, eventually gaining nearly 5,000 followers and the support of public figures like California Governor Jerry Brown, San Francisco Mayor George Moscone, and even First Lady Rosalynn Carter.
He later moved his group to a sprawling property in Guyana, where they developed a community later dubbed "Jonestown" with over 900 residents. In 1978 San Francisco Congressman Leo Ryan visited Jonestown in order to investigate claims of child abuse, and Jones ordered him killed by Jonestown "security guards" (he died, along with three journalists and one cult member). After that Jones had his followers drink grape Kool-Aid laced with cyanide. He was found later on with a single bullet wound to the head, adding to the other 917 people (including 276 children) who died.
