With this film, actress Mia Nygren became the first actress after Sylvia Kristel to play the Emmanuelle character in the official 'Emmanuelle' series. Emmanuelle would not be played by Kristel for the next to films. She was played by Monique Gabrielle in Emmanuelle 5 (1987) and Natalie Uher in Emmanuelle 6 (1988). Kristel reprises the role in Emmanuelle VI (1993).
Emmanuelle VI had hardcore scenes shot, but they were never used. These explicit scenes, which did not involve the main actors, were included in some television versions and turned up as extras on certain European DVD editions.
Hardcore shots were filmed but not used in many releases. There's at least a Canadian VHS available that features this scenes. You can find a comparison between the soft and the hardcore version here (no pornographic pictures) here.
