The two continued with a series of erotic films in the early 1960s. These films marked the beginning of a deliberate approach to filmmaking that each respective party would continue through their production careers — films made solely with the intention of turning a profit. Typical of these nudies were the screwball comedies "Boin-n-g!" (1963) and "The Adventures of Lucky Pierre" (1961), a film made for a shoestring budget of $7,500, which would become the duo's first great financial success; it made three times its budget upon its first release. Because film restrictions had not yet allowed for sexual depictions in films, the bulk of Lewis and Friedman's early work consisted of nudist camp features like "Daughter of the Sun" (1962) and "Goldilocks and the Three Bares" (1963), which appropriately billed itself as "the first (and to date the only) nudist musical".
