In 2016, she made several attempts to reach out to Watson on Twitter. "I'm a fellow actress like yourself & involved in an amazing women's movement I think you'd dig," Mack tweeted the "Harry Potter" and "Beauty and the Beast" star in January 2016. "I'd love to chat if you're open."

She tried her luck agin a month later, telling Watson in a thread: "I participate in a unique human development & women's movement I'd love to tell you about. As a fellow actress I can relate so... well to your vision and what you want to see in the world. I think we could work together. Let me know if you're willing to chat."

In March 7, 2016, right before International Women's Day, she tweeted Watson a third time, saying: "Would love to chat with a fellow change-maker!"
