Jana [5] and Casey are "swapped". Jana [5] is credited as Casey for the Interview. She is also identical to Christin [2].
Franzi and Camilla: This is the same girl, credited as "Franzi".
Consequently, "Mareen" is actually credited as "Camilla" and
Melina is actually credited as "Mareen"
Sabrina [5] is identical to Pinky (no pink hair in this flick)
Consequently, Simone [4] is actually credited as "Sabrina"
I do not think that Susi Dark is in this Movie.
