Dennis Vehlen’s review published on Letterboxd:
'Fiebre' was my third movie of Armando Bó and Isabel Sarli and possibly the weirdest one. It's showing slightly less nudity than 'Fuego' and 'Carne' but it might have an even more outrageous story, in which Isabel lusts after her favorite racing horse (named Fiebre). Isabel Sarli licking her fingers and biting her lips while watching her horse have sex for the first time (including full on horse dick) is truly what exploitation cinema is all about. There is also another epic spaghetti western like title song.
