It’s all in the title: At first glance, Ani FaNelli (Mila Kunis) seems to be the Luckiest Girl Alive: She’s got the dream job at a prestigious magazine, a gorgeous apartment and a fun, wealthy fiancé. But there’s a lot more to Ani than meets the eye, and it’s about to come rushing to the surface. When a true-crime documentarian invites her to dive into her traumatic past, Ani’s world comes undone, and she’s forced to confront the secrets she’s tried so hard to escape. Based on the novel by Jessica Knoll, Luckiest Girl Alive is a new thriller about a woman who must confront demons from her past that she had hoped never to face again.

Alongside Kunis, Luckiest Girl Alive stars a cast of familiar faces, playing the friends and colleagues of both Ani’s new life as well as the haunting reminders of her past. Below, we’ve collected a guide to those faces.

Mila Kunis

Kunis takes on the lead role of Luckiest Girl Alive. Ani is a successful professional forced to relive her horrifying high school experiences. While Kunis may be best-known for her sunnier roles on shows like That ’70s Show and films like Bad Moms and Forgetting Sarah Marshall, she dives into this heavier title with aplomb . And why shouldn’t she? This is the same Mila Kunis who started a twisted friendship with Natalie Portman in Black Swan. She’s no stranger to more serious subjects— even if for some of us, she’ll always be spunky Jupiter Jones, of Jupiter Ascending fame.

Attending a snobby private school on a scholarship, TifAni struggles with bullies and several traumatic events that will haunt her into her adult life. Aurelia popped up as Sheila in last year’s Fear Street Part 2: 1978 and played young Jessie in the Stephen King adaptation Gerald’s Game.

Connie Britton

The Friday Night Lights star plays Ani’s mother, who has a few guilty secrets of her own. Her relationship with her daughter is strained, to say the least — but Dinah always contends that she’s put Ani first. The five-time Emmy-nominated Britton most recently appeared on The White Lotus, but she’s got a filmography that stretches all the way from The West Wing through Nashville and American Horror Story.

She’s played by Jennifer Beals, one of the original stars of the landmark series, The L Word. Beals also played a terrific femme fatale in the Denzel Washington mystery, Devil in a Blue Dress and has popped up in projects as diverse as Flashdance, The Book of Eli and The Book of Boba Fett.
