Katherine Parkinson – Jen from Graham Linehan’s genius The IT Crowd – is set to star in ITV’s new sitcom Semi-Detatched. The series follows a disparate group of adult housemates disillusioned with their lives and trying to find a new focus. The series will also star The Royal Family’s Ralph Little, rapper stand-up Doc Brown and DCI Banks himself Stephen Tompkinson. The series continues ITV’s run of scripted comedies that has recently seen their resurgence as a British sitcom giant. The show will be written by Oriane Messina and Fay Rusling of Green Wing and Me And Mrs Jones fame. The Pilot is to be produced by Hat Trick Productions.
