I'm currently reading Manuel Puig novel. I have not seen the movie with William Hurt but did see the original cast on Broadway then Vanessa Williams. Both are outstanding.
The character Aurora is based on movies that Molina had seen and he added his own interpretation of that character that is glamorous and his own idea of what a woman she would or could have been. But the characters of Aurora are all heroines (panther woman, spider woman, zombie, Nazi spy) and these are strong women. He entertains his own imagination along in keeping Valentin interested.
That said Aurora has no race. She need not be white, black , Asian or Latina. Chameleon. But if ever they do a revival, this Aurora must have the sexiness of Zeta Jones, strength of Headley and a beautiful face (I'm sure make up and right lighting will do it).
And I hope they add more choreography.
