由《行尸走肉》原班人马拍摄的另一部恐怖题材的电影，也是制作人安迪·沃霍尔与导演保罗·莫里塞的另一部作品，风格与《行尸走肉》一脉相承，诡异和恐怖的气氛被表现得淋漓尽致，影片公映时由于血腥暴力和赤裸裸的性场景过多，因此这些场景大部分被剪掉了，标准版DVD则提供了完整的加长版本。
RED RINGS OF FEAR (ENIGMA ROSSO), 1978, 85 min. Director Alberto Negrin wraps up the SOLANGE trilogy in this giallo where more sexually precocious schoolgirls bite the dust. Fabio Testi is the police inspector on the murderer’s trail, and Christine Kaufmann is his girlfriend. Chock-full of red herrings, perverse twists, sleazy situations, outrageous dialogue and an out-of-left-field climax, punctuated by Riz Ortolani’s groovy score.
