Stephen Goldblatt, (born April 29, 1945) is a South African-born British cinematographer, noted for his work on numerous high-profile action films, including the first two entries in the "Lethal Weapon" series, as well as for his recent collaborations with director Mike Nichols and Tate Taylor.
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.
Redvers Buller Kyle (25 November 1929 – 18 November 2015) was a South African-born British broadcaster, voice over artist, actor and composer, best known for his work on the ITV network in the United Kingdom, spanning over forty years.

 She is a two-time 10-kilometre open water world champion, and an Olympic silver medallist.
Alan Edgar Stratford Johns (22 September 1925 – 29 January 2002), known as Stratford Johns, was a popular South African-born British stage, film and television actor who is best remembered for his starring role as Detective Inspector Charlie Barlow in the innovative and long-running BBC police series "Z-Cars".
Carry On Doctor (1967) is the fifteenth in the series of "Carry On" films to be made.
 It is the second in the series to have a medical theme.
 Frankie Howerd makes the first of his two appearances in the film series and stars alongside regulars Sid James, Kenneth Williams, Jim Dale, Charles Hawtrey, Joan Sims, Peter Butterworth, and Bernard Bresslaw.
 Hattie Jacques returns for the first time since "Carry On Cabby" four years earlier, while Barbara Windsor returns after her debut in "Carry On Spying" three years earlier.
 "Carry On Doctor" marked Anita Harris's second and final appearance in the series.
Carry On Cabby is the seventh in the series of "Carry On" films to be made.
 Released in 1963, it was the first to be written by Talbot Rothwell (although the first screenplay "Tolly" submitted to Peter Rogers was developed as "Carry On Jack") from a story by Dick Hills and Sid Green (script writers for Morecambe and Wise).
 Regulars Sid James, Hattie Jacques, Kenneth Connor and Charles Hawtrey are all present.
 Liz Fraser makes her third appearance (although she'd have to wait 13 years for her next Carry On) and Esma Cannon makes her fourth and final appearance.
 This was the first film in the series to feature "Carry On" regular Jim Dale, and the first not to feature Kenneth Williams.
Carry On Cleo is a British film comedy which was released in 1964.
 It is the tenth in the series of "Carry On" films to be made, and the website ICONS.a portrait of England describes "Carry On Cleo" as "perhaps the best" of the series.
 Regulars Sid James, Kenneth Williams, Kenneth Connor, Charles Hawtrey, and Jim Dale are present and Connor made his last appearance until his return in "Carry On Up the Jungle" six years later.
 Joan Sims returned to the series for the first time since "Carry On Regardless" three years earlier.
 Sims would now appear in every "Carry On" up to "Carry On Emmannuelle" in 1978, making her the most prolific actress in the series.
 The title role is played by Amanda Barrie in her second and last Carry On.
 Along with "Carry On Sergeant" and "Carry On Screaming!
", its original posters were reproduced by the Royal Mail on stamps to celebrate the 50th anniversary of the Carry on series in June 2008.
