Something fascinating about Korean movies from the 80s

Even in really low-quality movies that don't even qualify as B-movies, you see crowds of actors who are still famous and recognizable today.
There are also many cases where actors who could be considered top stars starred in truly absurd and strange movies.
For instance, the lead actress in "Wild Horse"—which wasn't even a theatrical release but Korea's very first video-only erotic film—was none other than Lee Mi-sook.
