I've seen "Familie Immerschaft" 1-4, Anja was not in them.
But, thinking about it, there's another movie with Anja, which could be a Billian-Picture. Just now, I can't remember the title.
German actress: Anja
Re: German actress: Anja
I have no doubt you are correct. I thought she might have been the actress who played the bride in part 3, but clearly not.
