UK pay TV broadcaster Sky and AMC Networks’ streaming service Sundance Now have both pre-bought true-crime docuseries The Killer Clown: Murder on the Doorstep.

The 3×60’ title was greenlit by London-based content creation, funding and distribution company BossaNova Media and is produced by indie prodco Flicker Productions.

It tells the story of Marlene Warren, a young mother who in the early 1990s was shot in the face on the doorstep of her Florida home by a person dressed as a clown.

The brutal murder was unsolved for 30 years until a surprising twist led to a breakthrough.

Jack Oliver, head of co-productions, Sky UK, said: “When BossaNova first presented The Killer Clown at its Development Day in 2023, we were convinced the title would resonate with our Sky Crime audience. It is a layered true crime story, stranger than fiction, imbued with a compelling tone which will hook viewers.”

Shannon Cooper, VP, programming, Sundance Now, said: “The Killer Clown is a captivating true crime with shocking twists around every corner. The elevated and elegant storytelling hits the mark perfectly for Sundance Now’s sophisticated audience and this one will leave viewers on the edge of their seats.

“We’re elated to be a part of this excellent series from the start and are thankful to BossaNova and Sky Crime for their continued partnership.”

In other BossaNova news, the company has revealed a raft of further deals for factual content.
