The dialogue used in the mass suicide/murder scene near the end of the film was taken almost word-for-word from an audiocassette found in a portable tape recorder under Jim Jones' chair. The tape recorder had weak batteries and was running at a much slower than normal speed, allowing the entire event to be recorded.
