when it come to paul verhoeven and erotic thriller and most people think of basic instinct and some maybe of showgirl . but verhoeven have make his best erotic thriller year before these two movie represent de vierde man . this film be mesmerize and mindblowing and above all the story be absolutely plausible and which make the whole experience even more intense . the performance by jeroen krabbe and renee soutendijk and thom hoffman be exceptional and and verhoeven direction do the rest . de vierde man make even basic instinct look quite tame . it can not get much good than this and a true classic of erotic nightmare cinema . positive and at least .
