The actress from [REL] Árvácska (1976) [Hungary] *DVD Rip added*, Zsuzsa Czinkóczi, is in it, though with a smaller and less "revealing" role.
When looking at this film on IMDB I found out something odd about Zsuzsa Czinkóczi: never really an actress, she was picked for Arvacska from an open audition. And rather than turning that into a fulltime acting career, according to IMDB she has worked at menial jobs most of her adult life but still appears in almost every movie by Ok Ketten's director, Márta Mészáros. Every one of the 16 movies after Arvacska she appeared in, right up to 2009, was directed by Mészáros. A strange career. Though I suppose maybe IMDB is incomplete, maybe someone knows.
