Jane Horrocks, Jessie Wallace, Celia Imrie, Lynda Baron and James (yes, I'm the son of William and I'm currently playing his grandson on the present day Corrie) Roache star in BBC Four's drama telling the story of how Coronation Street was born (on ITV, as the Beeb turned it down). With minutes to go until the live transmission of episode one of Coronation Street, creator Tony Warren is being ill in the toilets (you've been warned), actress Pat Phoenix is missing... and so is the cat from the opening shot. Granada's formidable bosses, Sidney Bernstein and his brother Cecil, are not enthusiastic. But together with producer Harry Elton and director Derek Bennett, Tony took up the battle to make the show no one wanted. He wants cobbles, a pub, seven houses and a shop, but above all, he wants northern actors. Led by casting director Margaret Morris and her young assistant Josie Scott, the hunt begins for the legendary cast - Doris Speed, Pat Phoenix, Violet Carson and William Roache.
