With only two films under her belt, by the end of 1960, 17-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 — 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 reaction 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 mostly made genre films of very specific and rigid structure and narrative. The movie also marked the first time Lončar was officially billed with her nickname Beba rather than her given first name, a practice that would be continued for the remainder of her career.
