Concha Velasco embarked on a journey to hone her skills in the art of dance, ultimately transitioning into a successful acting career within the realm of a revue alongside the renowned Celia Gámez. Her foray into the world of cinema began in 1954, with appearances in a string of minor films. As the regime of the authoritarian dictator Francisco Franco eventually came to a close, Velasco had the opportunity to collaborate with esteemed director Pedro Olea, among others, on a slate of higher-caliber films, including the critically acclaimed "Tormento" (1974) and "Pim, pam, pum... ¡fuego!" (1975),which significantly bolstered her professional reputation.
Her crowning achievement, however, was undoubtedly her portrayal of the illustrious Santa Teresa de Ávila in the 1984 film "Teresa de Jesús", a performance that cemented her status as a leading lady in Spanish cinema.
