i will not write at length about all the things this film made me think of.
but i can't omit the trivia that besides Juraj Herz two more local film directors were part of the cast.
Ivan Vojnár plays a devil (tempting St. Anthony).

and Johana Ožvold (né Švarcová) plays a lady cop (buddy of the boomer detective).

now, i could write at length about Johana Švarcová (later taking the surname of her hubby Ožvold) having together with Ventolin (before he became Ventolin) a band called Kazety (The Cassettes) and me choosing their hit called "Depilation" as an anthem of my genre "Bearded Ladies, Feminine Moustache" during the last Genre Cup. ...... anyway, it's gone.
last but not least, thx Sally for mentioning this film the way that made me to watch it.
