Devil in Disguise: John Wayne Gacy gets a new trailer from Peacock

August 28, 2025 by Amie Cranswick

Peacock has shared a new trailer and promotional images for the upcoming crime drama series Devil in Disguise: John Wayne Gacy.

The series tells the story of the victims of the sadistic serial killer (played by Michael Chernus) and the grief their families faced, while exploring the twisted layers of Gacy’s life during his reign of terror in the 1970s.

The cast includes Michael Chernus, Gabriel Luna, James Badge Dale, Michael Angarano, Chris Sullivan, and Marin Ireland. Watch the trailer below…

From 1972-1978, thirty-three young men were kidnapped, murdered and buried in a crawl space beneath their killer’s house. And no one was the wiser. Not for all those years. Why? He was charming and funny. Had a good, All-American job. Was a community leader. He even volunteered to entertain sick kids…while dressed as a clown. DEVIL IN DISGUISE: JOHN WAYNE GACY peels back the twisted layers of Gacy’s life while weaving in heartrending stories of his victims; exploring the grief, guilt, and trauma of their families and friends; and exposing the systemic failures, missed opportunities and societal prejudices that fueled his reign of terror.

Devil in Disguise: John Wayne Gacy arrives on Peacock on October 16th.
