An adman-turned-filmmaker whose commercial instincts rendered the line between those categories irrelevant, Lewis turned to gore as an exploitable element after being squeezed out of the 1960s sexploitation boom (early credits include 1961's The Adventures of Lucky Pierre (1961) and 1962's Nature's Playmates). After Blood Feast, he returned with increasingly ambitious variations on the theme: Two Thousand Maniacs (1964), The Gruesome Twosome (1967), The Wizard of Gore (1970) (which was seen in Juno), and The Gore-Gore Girls (1972), and others.
