Over the years, Darna has appeared in many films. The superheroine's popularity skyrocketed in 1951, when Royal Films produced a film version. Since then, a "total of 14 films" have been made portraying Darna and endless serialized stories in different comic books followed. Two Darna films were made by Royal Films, both starring Rosa del Rosario in "Darna" (1951) and "Darna at ang Babaing Lawin" (1952). A year after Darna was first serialized in 1950 in Bulaklak Komiks, Filipinos witnessed the first marvelous flight of Darna in the big screen. The Fernando Poe Sr. directorial starred Rosa del Rosario as Darna and Cristina Aragon as the supervillain Valentina, while Mila Nimfa portrayed the young Narda and Manuel Ubaldo played the role of Ding, Narda's little brother. The film was a huge box-office success. The 1952 film was based on "Darna at ang Babaing Lawin" (Pilipino Komiks No.120 January 5, 1952). In Eric Cueto's interview with Rosa in the Official Mars Ravelo Darna website, she revealed that in her flying scenes in Darna, she was actually flying over Quiapo with the aid of a helicopter. She was suspended in the air with help of cables attached to her body and the helicopter. All her flying scenes were shot at night to hide the cables. She nearly crashed on Quiapo Church in one of her flying scenes.
