Irene Verdú

Al Pereira, once a seductive and amoral detective, has become more and more of a right-winger over the years, until coming to be a champion of morals and modesty. But his path is crossed by the Alligator Ladies, sisters given over to sin and shamelessness, sent by their father, doctor Fu-Manchu, to bring Pereira back to the dark side (filmaffinity).

An aging schlock film director tries to make his final movie, but it won't be easy (imdb).
