Devil in Disguise: John Wayne Gacy, out on Peacock Oct. 16, dramatizes the real-life crimes of John Wayne Gacy , who was executed in 1994 for killing 33 young men and boys in the 1970s and burying many of them underneath his Chicago-area home. In 1980, he was found guilty of “murdering more people than anyone else in U.S. history,” as TIME reported back then.

The series, starring Michael Chernus as Gacy, draws heavily from a 2021 NBC News documentary series John Wayne Gacy: Devil in Disguise (also on Peacock) which features a rarely seen 1992 interview with Gacy that former FBI profiler Robert Ressler conducted in prison.
