This is a tough one, not only because of the subject matter. As it is often the case with the movies from former Yugoslavia, they offer a glimpse into the spirit of the era. At the same time they tend to be burdened by a mediocre script and, more often than not, a subpar delivery by the actors.
At the time when Pejzazi u magli has been released, heroin addiction was still a somewhat exotic topic in the former Yugoslavia. The contemporaries claim how the drug started to spread in the beginning of the 1980s. As it turned out, the children from well-off families were particularly susceptible to the drug.
Therefore I found the motif of a daughter mingling with the wrong crowd to be plausible, especially since they moved from Zagreb to Belgrade and were confronted with a faster tempo of life in the capital. This freedom of movement of sorts was not uncommon back then. We see that with a casual excursion to Dubrovnik and Mljet later in the movie.
The lead actress was no less than Anamarija Petricevic of Smogovci TV show fame. I can only assume this was her attempt at character roles. Also some heavyweight actors of the era were to be seen, both from Serbia and from Croatia.
I do have my doubt about the level of realism of the story, but I must say that some of the side actors seemed as if working on this movie wasn't their first contact with heroin. What did annoy me though was the way most of the actors used slang terms, pronouncing them as if they were names of exotic chemical compounds or magical formulas that shouldn't be said out loud. People, especially in the circles described here, simply didn't talk like that.
