Oh Hello! Leslie Phillips continues his two part exploration of the world of Carry On, looking at how the films evolved over the years. In part two, he examines their increasing loss of innocence as more relaxed rules on censorship made the series writers and producers ever bolder. The programme looks at the controversy over payments to the Carry On stars. It also examines the often overlooked Carry On TV series and the numerous stage shows the films spurned. Leslie discovers more about the films that were never made, before coming back to the series' last entry, 1992's Carry On Columbus. Julian Clary and others offer their thoughts on why, according to many, the last Carry On just didn't make the grade. There's also a look at why the franchise remains popular to this day - with stamps, cups, t-shirts and DVDs - as Leslie examines why Britain just seems to want to Carry On Forever. There are further great clips of Sid, Kenny, Babs, Charlie and the gang as well as interviews from the archives with Jim Dale, Bernard Bresslaw and Jack Douglas. Remembering the 1970s Carry On era are Shirley Eaton, Liz Frazer, Kenneth Cope, Anita Harris, Valerie Leon, writer John Antrobus and Carry On experts Robert Ross and Steve Gerard, as well as producer Peter Rogers and Director Gerald Thomas via the BBC's archives. And 'Kenneth Williams' and 'Frankie Howerd' continue to interrupt as their voices are brought back to life via impersonator and actor David Benson.
