I found only the cover and some parts of the movie on tube sites.
If the blurb on the back cover can be trusted, only one additional uncredited guy and one additional girl, credited as Bärbel, appear.
Unfortunately, the unknown guy and 'Bärbel' are hard to cap. These are the best caps of their face from that scene. 'Bärbel' looks familiar, but I wasn't able to find a profile on egafd or IAFD. I didn't find her on the Model-Index of the defunct site burningticket.com either.
Any idea who 'Bärbel' and/or the unknown guy are?
