Carey Mulligan is a Promising Young Woman in the trailer for Emerald Fennell’s new film

From visionary director Emerald Fennell (Killing Eve) comes a delicious new take on revenge. Everyone said Cassie (Carey Mulligan) was a promising young woman … until a mysterious event abruptly derailed her future. But nothing in Cassie’s life is what it appears to be: she’s wickedly smart, tantalizingly cunning, and she’s living a secret double life by night. Now, an unexpected encounter is about to give Cassie a chance to right the wrongs of the past in this thrilling and wildly entertaining story.

Written and directed by Emerald Fennell, the film stars Carey Mulligan, Bo Burnham, Alison Brie, Connie Britton, Adam Brody, Jennifer Coolidge, Laverne Cox, Max Greenfield, Christopher Mintz-Plasse, Chris Lowell, Sam Richardson, Molly Shannon, and Clancy Brown.

It is produced by Margot Robbie, Tom Ackerley, Josey McNamara, Ben Browning, Ashley Fox, and Emerald Fennell.

The film premieres at the Sundance Film Festival.
