So sorry to hear that about Olivia. She seemed to have a charmed life back in the 70’s. Big career successes, one right after the other, A string of hit records, Movies; Saturday Night Fever, then Grease.
However, I was certain that I heard her daughter had already gotten married quite a few months ago. Maybe that was just an engagement.
Years of worrying about her daughter may have kept Olivia under so much stress that it lowered her resistance to the cancer. I’m not pretending to be any expert, I have known a few people with severe cancer, and based on those experiences, I speculate. Her daughter seems a bit neurotic, attention seeking and nearly anorexic. She’s had numerous plastic surgeries.
And still her much older mom (Olivia) looks better, more a natural beauty.
I think you are getting her 70s film career mistaken with someone else’s. Grease was fantastic but that was her only success in film.
The only other movie she made in the 70s was “Toomorrow” and it was shown at one theater for one week.
Even if you go through 1990 she only made 3 other movies, “Xanadu”, “Two of a Kind” and “A Mom for Christmas” (a television film). None did well.
And she was not in Saturday Night Fever.
