I know we are a lot that have been looking for
Marianna. What was known besides that clip from Anabolic Assman 8 is that she did another scene with Christoph Clark in Euro Angels 21 : budalicious. On the cover they ID her as
Monica but sometimes Marianna. Page at IAFD.

After all this time I found something new : another alias that she used to make (as much as I know) 2 other scenes. That's not much but... twice as much.
She is listed in Egafd as
Carolina Greco. They list 2 movies, Italian movies. Here is the page in Egafd.

Look at the picture gallery, some of these pictures are clearly her. Unfortunately we don't see the details that would make it sure for you (big beauty mark or mole below her right breast, beauty mark on the outside of her left thigh), but we do see on the top picture of the gallery a small beauty mark on her left cheek just beside the mouth, check her clip you'll see that one.
I downloaded the clips and they are there, it is really her. She is more participative that in the Assman clip where you have the feeling she is watching All my children while being DPed. Maybe it was her 1st scene and these guys were always talking in English, and she obviously could not understand anything. In these ones, she is more active and into it, smiling, playing and giving these 'meaningful looks' at the camera.
I made a few screen captures but I don't know how to post them without using the attach file fonction. If you know how, tell me, I'll post some of them.
She also did a scene with a german guy called Conny Dachs (sometimes written Dax) but I didn't find it.

And there is more, I am pretty sure she used another alias but I have still to find convincing pics to be sure.
So she has done more... let's find it.
