With only two films under her belt, by the end of 1960, seventeen-year-old Lončar's cinematic profile was raised beyond all expectations. She next got cast as the female lead in Aleksandar Petrović's directorial debut—Avala Film-produced romantic drama "Dvoje"—alongside Miha Baloh and Miloš Žutić. Playing the role of mysteriously flirtatious Belgrade girl Jovana Zrnić, she once again got plenty of positive reactions in the press. The movie got released in late July 1961, and the following year got selected for the competition programme at Cannes. Although it ended up not quite matching the success of "Deveti krug" on the festival circuit, "Dvoje" got very good reviews for its innovative approach as a breath of fresh air in the Yugoslav cinema that up to that point had mostly been making genre films of very specific and rigid structure and narrative. The movie also marked the first time Lončar was officially billed using her nickname "Beba" rather than her given first name, a practice that would be continued for the remainder of her career.
