Pili and Mili (Spanish: Pili y Mili) was a comic acting duo composed of twins Aurora and Pilar Bayona (born February 10, 1947 in Zaragoza, Spain). They rosed to fame in early 1960s, becoming one of the biggest stars of the "child prodigy" movie genre that enjoyed a boom at the time. Their movies were musical comedies based on the same formula of mistaken identities. The twins were very popular in Spain, Mexico and Italy, but their career was short, lasting only from 1963 to 1970. When the success formula ceased to work, the duo dissolved.
