‘World’s Most Evil Prisoners’ Becomes Radial Original For Season 4

EXCLUSIVE: World’s Most Evil Prisoners, the British-produced crime series, is becoming a Radial Entertainment original.

The ten-part fourth season of the show from UK producer Woodcut Media will go out exclusively on Radial in the U.S., Canada, Germany, Austria and Switzerland, with Woodcut International selling it elsewhere, beginning at MIPCOM Cannes this week. Production began in September ahead of a planned 2027 premiere.

World’s Most Evil Prisoners is part of the World’s Most Evil franchise, which already runs on Radial. Seasons 1 to 3 of the show are already on Radial’s free-streaming services.

“Each series in the World’s Most Evil franchise offers a different lens on criminal behavior,” said Cristina Guggino, VP, Originals & Content Partnerships at Radial. “Prisoners examines how offenders manipulate and harm people behind bars, where confinement changes their methods and who is vulnerable. Season 4 digs deeper into those dynamics, building on what makes the series such a compelling part of the franchise.”

World’s Most Evil Prisoners takes a look at offenders doing life sentences, who go on to torture, kidnap and even kill while inside. Through the accounts of victims, friends and family, journalists and police, the series examines the dangerous prisoners.

“Each episode of this gripping series delves deeper into the psychology behind these harrowing crimes, uncovering never-before-seen cases while maintaining sensitivity toward the victims’ families,” said Koulla Anastasi, Managing Director of Woodcut International. “We are thrilled to announce Season 4 in partnership with Radial and look forward to presenting to buyers during MIPCOM.”

The deal was negotiated by Katie Carroll, Director, Originals & Business Development for Radial Entertainment, and Koulla Anastasi, for Woodcut International.

Radial, which is backed by funds managed by Oaktree Capital Management, has a library of more than 75,000 movies and episodes in genres such as true crime, reality, animation, action and westerns. Yesterday, we reported Radial is reviving horror and suspense brand A Haunting for a new 16-part series.

Kate Beal’s Woodcut, meanwhile, makes shows such as Confessions of a Female Serial Killer, The Murder of Meredith, World’s Most Evil Killers and Britain’s Most Evil Killers and Fiennes: Return to the Wild.
