Det kære legetøj AKA Sex and the Law AKA Danish Blue (1968) - Gabriel Axel
English-dubbed version. A relatively tame, lighthearted mockumentary featuring man-on-the-street interviews, a look inside porn shops, a narrator recounting her misadventures, and a porn shoot. I didn't see the still from Film as a Subversive Art (see above) - perhaps it's a promotional still, or perhaps it was cut in the US version.
