Lewis stopped working with Friedman after making "Color Me Blood Red", but continued to make further gore films into the 1970s. His next gore entry wouldn't come until 1967, with "A Taste of Blood", often referred to as the ""Gone with the Wind" of Gore" due to its relatively lengthy running time of nearly two hours. The following year would bring a more extreme take on the genre, "The Gruesome Twosome" (1967), most notable for incorporating an electric knife used to scalp one of the victims.
