Fiesta (1947)

Synopsis
Esther Williams moves from the swimming pool to the bull ring in this musical drama. Antonio Morales (Fortunio Bonanova) was once a champion bullfighter; now in retirement, Antonio and his wife (Mary Astor) have high hopes that their son Mario (Ricardo Montalban) will follow in his father's footsteps as a matador. However, Mario's great passion is music, and he longs to pursue a career as a composer. But there is a budding toreador in the family: Mario's sister Maria (Esther Williams), who has learned the basics of bullfighting from her sibling. Not wanting to be thought a coward, but with no desire to enter the ring, Mario allows Maria to disguise herself as him and take his place in the bullring, allowing her to compete in a traditionally male sport while Mario devotes his time to his music. Fiesta gave Ricardo Montalban his first English-speaking role, with Cyd Charisse appearing as Conchita, his love interest and dancing partner. Classical music buffs might notice that Mario's composition "Fantasia Mexican" is actually Aaron Copland's "El Salon Mexico." ~ Mark Deming, All Movie Guide
