The former publishing boss, who was portrayed by Asher Keddie in the TV drama about how she revolutionised the Australian women's magazine industry, also revealed more about what it was like to work with media mogul Kerry Packer in the 1970s.
According to The Sunday Telegraph, Buttrose praised Keddie's performance but said that her "lisp was overdone". She also revealed that Rob Carlton "captured Kerry's temper" but she didn't think "his great sense of humour" came across very well.
Buttrose said that she felt she had to "hide" her pregnancy as the editor of CLEO magazine almost 40 years ago, as Sydney was tough for working women. She said that Packer "blew his top" when she told him that she was expecting her first child and ranted about "bloody women who get pregnant".
She said: "Pregnancy was regarded almost as an illness; most women stopped work when they became pregnant. By working through my pregnancy, I later learned I had become a role model for other women."
Buttrose said that the show should be a "reminder to TV programmers that Australians actually enjoy stories about Australians".
It was recently reported that Channel Nine has poached the rights from The ABC to the sequels to Paper Giants. The ABC said that it was disappointed to lose out on the second and third instalments of the story but was "thrilled" it did so well in the ratings.
