Missing films:

Denmark

Letterboxd doesn't have the most of the Werner Hedman Agent 69 films, but it does have a couple. Weird, since they're all XXX. Kaktus is also adult, though it is not commercial pornogrpahy. The film by Wittrup is a noirish crime film.

Unge piger forsvinder i København (1951), Aage Wiltrup

In the Sign of the Taurus (1974), Werner Hedman

In the Sign of the Lion (1976), Werner Hedman

Sweden
The films by Ahlberg and Dirty Diaries are XXX, so no surprise that they're not on Letterboxd. More surprising is that the films by Arne Mattsson aren't on the site, given that he has been compared to Bergman as a filmmaker. The film by Ohberg is a crime film. I have no idea what the Las Wallen film is or why it's on my list, but it might be an avant garde, birth of a baby kind of film?
