These are (cropped) caps plus a lobby card. I am interested in this guy, because I'm a bit of a historian of Germany's 1970s sex films, and he's been in 10 of those - in other words I should really know who he is and I don't, and that irks me especially as his appearances cross both softcore and hardcore movies. His movie parts are all very small, usually just a cameo; I got the impression though that he's not a normal movie extra, but probably a crew member pulled in front of the lens - in Zwei geile Hirsche auf der Flucht he plays a cameraman (or director) in a small film-in-film scene.
The films I have spotted him in are (most, if not all, are on VEF):
Bienenstich im Liebesnest
Hausfrauen-Report 4. Teil
Hurra, die Schwedinnen sind da
Jagdrevier der scharfen Gemsen
Kasimir der Kuckuckskleber
Liebesgrüße aus der Lederhose 3. Teil
Rosi Nimmersatt
Sanitätsgefreiter Neumann (loop)
Schulmädchen-Report 9. Teil
Zwei geile Hirsche auf der Flucht
P.S.
in my database I have given him the nickname Waldschrat - which I mostly mention to have a distinctive search term for this post, but also: if you refer to him by that name I would instantly know who you are talking about
