In the original album and stage play, there is a line referring to Evita as "the new world Madonna with the golden touch". In the film, it was changed to "she's Our Lady of the new world with the golden touch". This was done since the actress playing Eva is Madonna.
Antonio Banderas got the role of Che by submitting a self-made audition tape and performing all the musical numbers in front of Sir Alan Parker at a dinner meet in Miami.
Michelle Pfeiffer also was considered for the role of Eva Perón, and when the film was to be directed by Oliver Stone she even had taken a few months' voice training for the role.
Madonna was cast after she wrote a long letter to director Sir Alan Parker convincing him she was perfect to play the role. The letter was accompanied by a copy of her video for "Take A Bow" where she had specifically asked the director that it should resemble the '40s and '50s. Also in the letter she compared her life to Eva Peron's; both lost a parent as a child, and both arrived young in the big city with no money or friends but managed to succeed.
Madonna changed costumes 85 times, more than Elizabeth Taylor in Cleópatra (1963). Madonna wore 39 hats, 45 pair of shoes, and 56 pairs of earrings. Because of this, Madonna was an entry in "Guinness World Record" that year. Impressive but not an all-time record. Donald Brooks designed a 125 piece wardrobe for Julie Andrews for the 1968 musical Star!
