‘Peep Show’ may have finally come to an end last year, but David Mitchell and Robert Webb are certainly not done yet. The comedy duo are to reunite for a new sitcom entitled ‘Back’ for Channel 4, about a dysfunctional family in the pub business.

The new show is to be written along with Simon Blackwell, who helped co-write some of the later episodes of ‘Peep Show’ which finally came to an end last December, after nine series and 12 years. He’s also a sometime collaborator with Armando Ianucci, working with him on political satires ‘The Thick of It’, its movie spin-off In The Loop and American version ‘Veep’.

Mitchell will play Stephen, who inherits the family’s pub business after the death of his father, but his plans are thrown off course when his former foster brother Andrew (played by Webb) re-appears in his life and wants to join in.

Stephen’s sister Cass and mother Ellen are to be played by Louise Brealey (Molly Hooper in ‘Sherlock’) and Julia Deakin (from ‘Spaced’).

Potential release dates are not yet known, but a pilot episode is due to be recorded first, with Ben Palmer from The Inbetweeners Movie behind the camera. The duo’s own That Mitchell & Webb Company will be making it in conjunction with Big Talk.

Phil Clarke, head of comedy for Channel 4, said: “To have Mitchell and Webb and Simon Blackwell working together is a very exciting prospect. It’s a unique configuration of some seriously big comedy minds. Simon has written a very funny and clever script with a strong emotional heart that takes Robert Webb and David Mitchell in a new and genuinely intriguing direction.”

Big Talk Productions’ CEO Kenton Allen also released his own reaction. “Blackwell, Mitchell and Webb are some of the finest comedy minds I’ve ever encountered, a supergroup of incredibly witty individuals. The show was an absolute pleasure to develop with them and I only hope the audience will laugh as much when they see ‘Back’ as I have when spending time with these masters of their craft.”
