Wednesday, 9.25pm, ABC1 This fictional British Indian family is back in a new six-part series. Sanjeev Kumar uses the flat behind his dad’s shop in London’s Hounslow to interview visiting celebrities. He sees himself as a rising star but the family — his father Ashwin, mother Madhuri and grandmother Ummi — keep railroading his best efforts. This week’s guests include Daniel Radcliffe, Chevy Chase and Olivia Colman; Ashwin tries to get them to advertise his shop’s products. The show, The Kumars at No 42, launched in 2002 and was a hit in countries from Russia to Africa.
