Devil In Disguise: John Wayne Gacy | Preview (ITV1)

ITV will launch critically acclaimed scripted crime drama Devil in Disguise: John Wayne Gacy in late January 2026 on ITVX and ITV1. The series is currently rated 95% fresh on Rotten Tomatoes.

Prepare to take a deep dive into the mind and life of one of America’s most notorious serial killers with this drama that tells the terrifying story of John Wayne Gacy.

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.

Michael Chernus (Severance) leads the cast as John Wayne Gacy. He is joined by Gabriel Luna (The Last of Us), James Badge Dale (Savant, 1923), Michael Angarano (This Is Us, Oppenheimer), Chris Sullivan (This Is Us), and Marin Ireland (The Irishman, The Umbrella Academy).

Devil In Disguise: John Wayne Gacy begins Friday 30th January at 9pm on ITV1.
