Isela Vega was born in Hermosillo, Sonora, Mexico on November 5, 1939. The young beauty was named Princess of the 1957 Carnaval in Hermosillo, and parlayed that into work as a model. She also had some success as a singer before turning to acting. (Her composition "Bennie's Song" was used in Tráiganme la cabeza de Alfredo García (1974), which features her singing.) She made her film debut in the Pedro Armendáriz movie Verano violento (1960). From her beginning in small roles in Mexican films in the early 1960s, her career grew and Isela became very popular as a sex symbol in the late 1960s. (She would appear nude in a multi-page feature in Playboy Magazine's July 1974 issue.) In addition to her Mexican films, TV shows, and stage appearances, she also worked in a number of foreign films, most famously in Sam Peckinpah's Tráiganme la cabeza de Alfredo García (1974), for which she received a Best Actress Ariel Award nomination in 1975. (Previously, Vega had been nominated for a Best Actress Ariel for her turn in Las reglas del juego (1971) in 1972.) She had made her United States film debut the year previously in Con furia en la sangre (1973) (the U.S.-Mexico horror cheapie La cámara del terror (1971) doesn't really count) and continued to appear occasionally in small parts in American films and TV until the late 1990s. In addition to her work as an actress, Vega produced, wrote and directed Las amantes del señor de la noche (1986), and has written and produced other films. She has a son whose father is Alberto Vázquez, and a daughter (Shaula, an actress) whose father is Jorge Luke.
