Producer Stephen Lambert has committed his future to the Discovery and Liberty Media-owned All3Media by re-signing a deal until 2020. As part of the pact, Lambert will launch a new drama division in his Studio Lambert banner.

Lambert launched Studio Lambert in 2008 with initial backing from All3Media, before it was fully acquired by the super-indie in 2012. It specialises in factual and factual entertainment formats. Credits include Undercover Boss, Four In A Bed and Gogglebox.

There has been speculation that Lambert is in the running for the vacant chief exec position at All3Media. Previos chief exec Ramzan Golant exited in September.

Lambert is currently recruiting for a head of drama for the new unit.

“We are in the golden age of scripted television on both sides of the Atlantic,” said Lambert in a statement. “I’m excited by the prospect of us creating some hit scripted shows as well as building up our successful non-scripted slate.”
