In the 1970s films with Vilma Santos as Darna are iconic, influencing people's perception of the character for some 30 years afterwards. In these films, Darna is already a teenager and she has to swallow the stone each time she transforms, as it comes out of her mouth whenever she changes back to Narda. Her home planet was not named. "Lipad, Darna, Lipad"! (1973) is the first and only trilogy of the superheroine. On March 23, 1973, Darna breaks all box-office record. It was the highest-grossing Darna film in Philippine film history and considered a turning point in Vilma's career. On the opening day of the film, the cast gave away free Darna dolls. Coca-Cola also promoted the film by giving away Darna characters mask. It was also the first Darna film where Darna and Narda were played by the same actress. Unfortunately, there is no existing copy left of this classic film. The line "Ding, ang bato!" ("Ding, me the stone!") from the film "Lipad, Darna, Lipad", became a favorite catchphrase, though it was not in the original komiks. The film had three episodes: (1) "Impakta" directed by Maning Borlaza. It starred Gloria Romero as Miss Luna, a school teacher who has a dark secret. She is actually a flying flesh eater creature at night; (2) "Babaing Ahas" directed by Elwood Perez. It starred Celia Rodriguez as Valentina, a campy supermodel/gorgon. One scene has the actress naked in bed being caressed by a dozen snakes; and (3) "Babaing Lawin" (Hawk Woman) starring Liza Lorena as Babaing Lawin and Rod Dasco as Aguila directed by Joey Gosiengfiao.
