ET spoke with Hathaway at the Toronto International Film Festival last month, where she dished about her first acting gig since giving birth -- the star-studded Ocean's Eight, aka the all-female Ocean's Eleven. Sandra Bullock, Cate Blanchett, Rihanna, Helena Bonham Carter and Mindy Kaling are all set to appear in it.
"Oh my God, I have so many questions," she told ET about working with her fellow A-list ladies. "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."
