La Virtud Desnuda is a Mexican film made in 1957. It is famous for being the fourth Mexican films where there was nudity*. However, it was probably the most controversial due to the fact that there were approximately 10 scenes where Columba Domínguez appeared nude.
Columba had been married to successful Mexican film director Emilio Fernández who made social dramas that were didactic, and for the large part, virginal (His main character NEVER kiss). So this was a large step forward.
*The first actress to bare her breasts in a Mexican film was Ana Luisa Peluffo. When her father saw the film, he began collecting money from family members because he thought his daughter was having economic problems.
