The Hugo actress will reprise Sissy Spacek's 1976 role in the Stephen King adaptation, with filming beginning on June 1.
Kimberly Peirce (Boys Don't Cry) is helming the Carrie remake, which is said to be based more on the original novel than Brian De Palma's classic film adaptation.
It's going to be very well done. I don't want to jinx it, but [Peirce] is a genius, genius, genius director," Moretz told ComingSoon.net.
"I would never do it with someone that I don't trust. I trust her more than a lot of the directors I've worked with. She's the right woman for the job.
"I'm actually not looking at the original, even though De Palma's movie was one of the best movies ever made," Moretz continued. "It's completely iconic, and I'm proud to be able to be doing a retooling of it. We're kind of going off the book.
"It's darker and much more psychological. More Black Swan. You're really looking into her mind and it really looks into the relationship of Margaret and Carrie. It's set in modern time, so it's a lot different."
Julianne Moore has formally been offered the role of Carrie's mother Margaret White, although she is yet to officially accept.
Carrie will debut on March 15, 2013.
