The movie was shot in the middle of a big economic crisis for the Mexican cinema. Production was about to be shut down a few times and the famous scene with the mannequin being cremated was filmed only once because they couldn't afford another mannequin.
Luis Buñuel and Rodolfo Usigli worked on a screenplay together but in under 2 weeks they parted ways because Usigli wanted no changes made to his novel and Buñuel wasn't interested in some elements of it and would drop them.
Final film of Miroslava.
