Ricky Gervais may be planning an Extras spin-off – featuring Stephen Merchant’s dopey agent and Barry from EastEnders as a crimefighting duo.

The hit BBC sitcom comedy ended after two series, with Ricky declaring that the recent Christmas episode would be the last.

But actor Shaun Williamson, who plays Barry, has revealed that Ricky has come up with another idea for his character and useless agent Darren Lamb.

He told Heart FM: “I would have loved another 10 series of Extras but I can totally understand them wanting to call it a day.

“The one thing we did bandy about, half in jest and half seriously, was the idea of a spin-off for my character Barry and the agent.

“Ricky thought they could go around in a camper van solving crimes or something.”

He added: “That’s strictly on the backburner for now as Ricky is busy in Hollywood at the moment. I’d jump at the chance to work with him again.”

Shaun also revealed that he nearly turned down the Extras role.

“I thought for about 10 minutes about not taking it and then I realised I might never get the chance to work with Ricky and Stephen again.

“I am so proud to have been involved with Extras and I can understand them wanting to finish it.

“They’ve got so much more going for them and I think they have got a great film in them to make, whether it’s an Extras film or just a great British film, and I’m sure they’ll make it.”
