Referring to France Nuyen's firing from the film version of "The World of Suzie Wong," the famed show biz columnist Louella Parsons wrote the following in the daily newspaper, the Chicago American, on Tuesday, February 27, 1962 (page eight) when Nuyen was cast opposite Charlton Heston in Diamond Head (1962) in '62": "As for little Miss Nuyen, things have been going much better for her recently since her bad start when she was taken out of 'The World of Suzie Wong' when she put on too much poundage worrying over M. Brando." And in its review of the film, the TV Guide site also references the firing: "Nuyen was distressed at reports from California that her lover, Marlon Brando, was carrying on with another woman, and drowning her sorrows in food. The actress gained so much weight that she was fired from the part."
