While Rihanna's character -- and the plot of Ocean's Eight -- are still being kept under wraps, the film will be a spinoff of the Ocean's Eleven films starring George Clooney, Brad Pitt and Matt Damon.
ET caught up with Anne Hathaway shortly before filming began on the movie, where she couldn't stop gushing about joining the star-studded cast -- which also includes Sandra Bullock, Cate Blanchett, Helena Bonham Carter, Sarah Paulson, and Mindy Kaling.
"Honestly, right now I am looking forward to the hair and makeup trailer," she said. "Oh my god, I have so many questions… I just feel like I am getting to peer behind the best curtain ever to see what everybody does."
"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," Hathaway added. "So I cannot believe I get to do that with the women on this."
