During the peak years of the Italian film industry in the 1960s and 70s, there were numerous films released which never received a theatrical release in the U.S. and are completely unknown to American audiences. Of course, some of these are forgettable but there are several that deserve a second chance at being re-discovered and Violenza al Sole (English title: Violence in the Sun aka Blow Hot, Blow Cold aka Hot Blood in the Veins, 1969), directed by Florestano Vancini, is a prime example. It is also a fascinating anomaly in the careers of the four main actors, Giuliano Gemma, Rosemary Dexter, and two stars who are most often associated with director Ingmar Bergman, Bibi Andersson and Gunnar Bjornstrand.
