Radio Times are celebrating the best of TV, radio and books with a host of stars and TV insiders appearing on The Green at Hampton Court Palace for the Radio Times Festival. Every ticket includes access to gourmet food stalls, a shopping village, free events and screenings. It’s a good question: how do you get into TV? Bafta recognised writers Kwadjo Dajan (Cilla and Mrs Biggs), Regina Moriarty (Murdered by My Boyfriend) and directors Marcel Mettelsiefen (Children on the Frontline) and Sarah Walker (The Crash and The Cut) have a bunch of practical suggestions to impart. Listen up as the foursome dispense valuable advice on how to enter the bewildering world of television. Under 5 years go free, but must be seated on parents lap. Over 16s must purchase an adult ticket.
