Francesca, by then known mainly as Kitten Natividad, was introduced to Russ Meyer by fellow dancer Shari Eubank, a performer in Meyer's 1975 film "Supervixens." Meyer hired her to narrate his movie "Up!" In it, she was shown sitting nude in a tree, quoting the poetry of Hilda Doolittle, and acting as a Greek chorus to the nonsensical action. Meyer was so impressed he wanted her to star in his next feature, "Beneath the Valley of the Ultra-Vixens," one of several collaborations between Meyer and film critic Roger Ebert. Meyer paid for a second breast enhancement and voice lessons to eliminate her accent. Due to the tragic results of her breast enhancement surgeries she deeply regretted what she was talked into doing. She left her husband for Meyer during the filming, and they lived together as a couple for most of the next 15 years.
