When Terry Levene distributed this film in the late 1970's, he replaced a few of the establishing shots with those of American locations. For an establishing shot of the Rome youth center where Tanzi meets Stefano, Levine used a shot of the Manhattan night club "Fascination". Strangely enough, in the later Lenzi film Da Corleone a Brooklyn (which also starred Maurizio Merli as an Italian policeman), Merli drives by the club "Fascination" after he arrives in New York.
