Carry On Emmannuelle: Carry On Emmannuelle is the 30th in the series of "Carry On" films to be made, and was released in 1978.  This was the last "Carry On" film to be made until "Carry On Columbus" in 1992.  The film was to be the final "Carry On" for many regulars, including Kenneth Williams (in his 26th "Carry On"), Kenneth Connor (in his 17th), Joan Sims (in her 24th) and Peter Butterworth (in his 16th).  Jack Douglas and Jim Dale are the only regulars from the original run of Carry On films to bridge the gap to "Carry On Columbus".  Beryl Reid and Suzanne Danielle make their only appearances in the series here.  The film featured a change in style, becoming more openly sexual.  This was highlighted by the implied behaviour of Danielle's character, though she does not bare any more flesh than any other "Carry On" female lead.  These changes brought the film closer to the then popular series of X-rated "Confessions..." comedies, or indeed the official "Emmanuelle" films it parodies.  This, and "Carry On England", were the only films in the series to be certified AA by the then British Board of Film Censors, which restricted audiences to those aged 14 and over.
