Continuity mistake: When Eva is campaigning for Peron's release from prison, at one point she's at a microphone, standing among a crowd of people. There's a woman in an orange dress who's off to her left in the wide shots, but in the close ups of Eva, the woman is suddenly directly behind her.
Continuity mistake: While she's singing "Buenos Aires" Madonna's stomach gets bigger and smaller all the time. For the exterior night time shots in Buenos Aires, she's pencil thin; for the shots in the nightclub she's noticeably larger. Again, when she's descending the stairs from Magaldi's flat, she has her suitcase covering her stomach. Madonna was pregnant at the time of filming, but as such it is still a mistake within the film to see her figure change that drastically for no reason in the storyline.
