The Channel 4 commissioner of Oscar-nominated doc For Sama is stepping down after more than a decade to join Hillary Clinton’s fledgling production company.

HiddenLight Productions has appointed Siobhan Sinnerton as its creative director and senior vice-president of unscripted.

Sinnerton joined C4 in 2010 as commissioning editor, news and current affairs. As well as Syria doc For Sama, she ordered docs such as The Hunt for Jihadi John, Children on the Frontline and Myanmar’s Killing Fields as well as series Supershoppers and 24 Hours in Police Custody.

She later added immersive content to her commissioning brief, bringing virtual reality into the documentary space with Grenfell: Our Home, which took people inside the building via computer-generated animation.

Former presidential candidate and one-time First Lady of the United States Clinton and her daughter Chelsea teamed up with Sam Branson to launch HiddenLight in December, hiring Sundog Pictures chief Johnny Webb as chief executive.

Based in London, New York and Los Anfgeles, the company's first commission is Gutsy Women, an Apple+ TV series based on a book by the Clintons.

Sinnerton described HiddenLight as “one of the most exciting companies to launch in recent years,” adding: “They truly understand the difference that television can make to people’s lives and, through their founders, their experienced team, their nurturing approach to talent and their transatlantic footprint, the company has the opportunity to make a huge impact globally.”
