'Box' in the following refers to the DVD box cover.
Four males appear, but five (six?) male names appear on either the box or the screen or both -
- Joey Murphy is credited on the box but not on screen
- Jean Yves LeCastel is credited as Jean le Castel on screen but not credited at all on the box
- Yves Baillat is so credited on both box and screen
- Alain L'Yle is credited as Alain on both box and screen
- Eric is credited on the box and probably on screen as Cilia
From the on-screen credits it would seem safe to assume that Yves Baillat, Alain L'Yle and Jean Yves le Castel appear, plus one other.
Two females are credited on the box - Dolly Buster and Suraya Jamal. Three females are credited on screen - the above two plus Alexandra.
