Mystique

Georgina Spelvin's character in Mystique is named "Alma". The latter is also the first name of composer Gustav Mahler's wife. Mahler's "Songs on the Death of Children" is featured prominently in Mystique. Samantha Fox's character is named "Cosima". The latter is also the first name of the second wife of composer Richard Wagner. Cosima Wagner historically had issues with her contemporary, Gustav Mahler.

The film's credits list Erica Richardson as playing "Elizabeth" and Yolanda Bonnea as playing "Lotte". Initially, Samantha Fox introduces the new maid as "Elizabeth" and the new laundry girl as "Lotte". Later on, however, Fox calls the same maid "Lotte" during a photo session. The latter is the correct identification. Therefore, Lotte the maid is played by Yolanda Bonnea and Elizabeth the laundry girl is played by Erica Richardson.
