Although she admitted her failure to come forward, Fonda concluded by saying how proud she was that female actors were now courageous enough to speak out.
We only speak of this case for a week: the producer, the most well-known of Hollywood, Harvey Weinstein, has just been sacked from his own company after accusations of sexual assault.
"I only met Harvey when I was old and Harvey goes for young because that's more vulnerable", said Fonda, who declined to speak on Arquette's behalf, leaving it up to her friend to disclose details of the allegations.
"I was not that bold", Fonda replied.
Apparently, sometime past year, Weinstein victim Rosanna Arquette confided in Miz Fonda about the sexual harassment she suffered through thanks to Harvey. She says she was abused as an 8-year-old child and explains why therapy was important for her recovery.
Fonda declined to discuss what Arquette told her.
She said she now regretted staying silent.
"I found out about [Harvey Weinstein] about a year ago".
When asked why Fonda didn't say anything publicly after she spoke with Arquette, Fonda said, "I guess it hadn't happened to me, and so I didn't feel that it was my place".
"It came as a shock and a great disappointment, this male entitlement", she told Amanpour.
Interviewed by CNN International, the actress Jane Fonda is back on the case.
"You're scared because you feel like... you'll never work again because they have so much influence... and you won't be believed", she added.
Fonda told Amanpour that Weinstein's pattern of abuse is not an isolated phenomenon.
"I had one experience with a French director, he was going to cast me in a role that required the character had an orgasm and he said to know whether I should be cast he should find out what orgasms I had".
"I got hired even though I didn't give him what he wanted", she recounted, noting she had nonetheless kept quiet about the proposition.
"It's unacceptable and we can't ever forget that and we have to stand up to them". And what kind of a message does that say?
