Censorship in featuremovies

Blue Movie (1971)
In 1971 in the Dutch film world the sex wave also eruptedl. Both Mira and what I see, but particularly in Blue Movie, nudity and sex played an important role.
In Blue Movie there are two classics in the field of nudity in film: first, the scene in the elevator in which Hugo Metsers has sex experience with a roommate while half the flat before the elevator doors are waiting, and secondly, the final scene of the film, in which one sees (almost complete erection )of the actor.
This was unprecedented in the Dutch film.
