"Let me know if you're willing to chat", she added on February 19, 2016, despite the fact that Watson never responded.
Ms Mack is best known for her role as Chloe Sullivan in the show which aired from 2001 to 2011 chronicling the early days of Superman. "I'd love to chat if you're open", Mack, 35, tweeted at Watson, 28, on January 24, 2016.
Almost a month later, Mack again attempted to contact legitimate humanitarian Watson about her "unique human development & women's movement", adding "I think we could work together".
Speaking after Mack's arrest, Samia Shoaib told Page Six she was once considered a target for recruitment into the alleged cult. The Requiem For A Dream and The Sixth Sense actress said she met Mack during a 2013 audition, and that she appeared "fragile and gaunt" and was "definitely physically suffering" at the time.
Keith was arrested on charges of sex trafficking and forced labor conspiracy at the end of March.
"Mack and other ... masters recruited ... slaves by telling them that they were joining a women-only organization that would empower them and eradicate purported weaknesses the NVIVM curriculum taught were common in women", prosecutors said.
According to a statement from the U.S. Attorney's Office in the Eastern District of New York, Mack was allegedly "one of the women in the first level of the pyramid immediately below Raniere".
The women, branded with Raniere and Mack's initials, were also allegedly blackmailed into becoming sex slaves for the founder's benefit. She was ordered held without bail over the weekend ahead of another bail hearing set for Monday. Both Raniere and Mack face mandatory minimum sentences of 15 years in prison if convicted. According to an affidavit filed on Friday, Mack's legal team and prosecutors have agreed to delay proceedings against the actress until 3 May because they're "engaged in plea negotiations, which they believe are likely to result in a disposition of this case without trial".
