Isela Vega starts her career in 1960 when she appears in Verano Violento (Violent Summer) by Alfonso Corona Blake, the first female credits are for Erika Remberg and Adriana Roel. In those years Mexican cinema takes advantage of women's fashion: all the young actresses were filmed in miniskirts, see-through baby dolls and bikinis. Throughout that decade, Isela constantly appears in credits that are rather eloquent: SOS Conspiración bikini (SOS Bikini Conspiracy), Mujeres, mujeres, mujeres (Women, Women, Women), Las pecadoras (The Sinners), La cama (The Bed), Las sicodélicas (Psychedelics), (where she alternates the firstcredits with (Maura Monti, Amedee Chabot and Elizabeth Campbell), El matrimonio es como el demonio, (Marriage is like the devil), El deseo llega de noche (Desire comes at night), (where she already has the second credit), Las golfas(Tarts), (where she has the lead role). From that period, she stands out for her beauty, her discipline and her capacity to challenge the epoch's moral standards in spite of the limits that her characters suffered. She works by the job: in 1969, her name appears in nine films. When Francisco del Villar calls her for the shooting of Las pirañas aman en cuaresma (Piranhas love in Lent), based on a text by Hugo Argüelles, Isela brings different shades to the young and delightful widow's role. In 1972 she obtains her first Ariel nomination for Las reglas del juego (The Game's Rules). In 1974, Sam Peckinpah calls her to form part of Tráiganme la cabeza de Alfredo García, (Bring me Alfredo García's Head), regardless of the negative reactions caused by the film, the -at that point-, young Roger Ebert discovers an actress as "erotic as the young Anna Magnani" and by Warren Oate's side they achieve "a sacred acting". Possibly without having read the American critic Arturo Ripstein, he calls her in 1977 to give her a co-star with Mario Almada in La viuda negra (Black Widow), based on the theater play by Rafael Solana that would be banned during José López Portillo's administration. It is in 1984 when it gets released and receives the first Ariel. In its days, it combines theatre and cinema; thanks to her popularity as a striptease artist, a peculiar phenomenon arises; her acting on the proscenium are authentic swearing and double entendre duels. Isela is courageous with her admirors and draws the limits. She participates in "Ficheras films" but does no longer work by the job. In 1986, she produces and directs Los amantes del señor de la noche (Lovers of the Night's Master), another story by Hugo Argüelles. From La ley de Herodes (Herodes Law), by Luis Estrada and without any need for bikinins, every performance by Isela Vega is a singular and profane moment. Carlos Monsiváis summarizes it: "Professional provocateur, sex symbol, idiomatic defiance".
