|Lydia Rose Bewley and Jessica Knappett|
The show, called Drifters, features three of the stars of the spin-off film - Lydia Rose Bewley (represented by Curtis Brown) and Jessica Knappett, who played clubbers Jane and Lisa, and Lauren O'Rourke, who played Neil's girlfriend.
The three will play three twenty-something young women Meg (Jessica Knappett), Bunny (Lydia Rose Bewley) and Laura (Lauren O'Rourke), experiencing their first slice of the real world post-University - making terrible decisions, but having a brilliant time doing it.
For the ‘Drifter' girls it's time to start asking some serious questions: What do they do now? Who are they going to be? And is it ok to shag someone with a sweat problem if you haven't had sex in twelve months?
Not fully paid up career women, they take on a series of menial jobs in their home town of Leeds that allow them to cling to the last vestiges of girlhood - that stage where everything is terrifying and exciting in equal measure. It's all about the fear that comes with knowing you should take more responsibility and the excitement that comes with knowing you still don't really have any at all.
Bob Mortimer will star as Meg's father Frank with the cast also including Nick Mohammed and Dylan Edwards.
As well as starring in it, Drifters has been written by Jessica Knappett (represented by United Agents) who studied Drama and English at The University of Manchester.
Iain Morris, one of the creators of The Inbetweeners, is executive producer on Drifters.
He said: "We're lucky and delighted to be involved with Jess's new sitcom. "We knew from our time working with her while shooting The Inbetweeners movie that she was hysterically funny, not least because she created the production's unofficial drinking den, Bar Knappett, in her hotel room."
Channel 4's comedy commissioning editor, Fiona McDermott, said: "Drifters promises to be a really funny sitcom about really funny girls. It's that simple. Jess is a fab talent and it's great to be working with her."
The series is being produced by produced by Bwark Productions, a Zodiak Media Company, and the company behind E4's multi-award winning series and film, The Inbetweeners.
