"Honestly, right now I am looking forward to the hair and makeup trailer," Hathaway told ET’s Cameron Mathison at the Toronto International Film Festival. “Oh my god, I have so many questions. They are fun and a lot of them are moms, so I am excited that my first film back as a mom, I get to work with women who have done it before and I get to ask them questions about that."
Hathaway, who was at the festival promoting Colossal, added that she's just as thrilled to learn from the actresses on a professional level.
"I just feel like I am getting to peer behind the best curtain ever to see what everybody does," she gushed. "My career has been a series of working with people that are better than me and trying to pick up things that they do, pull them into my life and hopefully get better myself. So I cannot believe I get to do that with the women on this."
She is also set to star in Live Fast and Die Hot, a drama based on a memoir by Jenny Mollen, which deals with the struggles of juggling motherhood with other responsibilities. Hathaway says her own transition into parenting was a huge influence in why she took the role.
“The book landed in a very real way because I knew what she was talking about,” she explained. “Which is not to say you need to be a mom to understand it. Jenny Mollen is just a really funny writer and you would enjoy it whether or not you are a parent, but for me it hit a chord.”
