Meet Everyone Who Gets Terrorized by Octavia Spencer in Ma

The Oscar winner plays the titular Ma (real name: Sue Anne) who takes her new friendship with a group of teens to obsessive and horrifying heights.

Next to Spencer, Booksmart alum Diana Silvers is the lead of Ma as new girl in town Maggie, who is the one who initiates the connection between Ma and the group of high schoolers.

Ma is no Cape Fear, but Juliette Lewis still gives her role as Maggie's mother, Erica, her all.

Corey Fogelmanis has appeared in everything from Girl Meets World to the horrro series PrankMe. In this he takes on the role of Andy, who has a not-so-subtle crush on Maggie and also finds himself the recipient of unwelcome attention from Ma.

The Hart of Dixie and Speechless alum appears as one of Maggie's new friends, Haley, who doesn't know when to zip her lips. (Fortunately, Ma helps her out with that . . .)

After nabbing roles in Power and The Knick, you can see Gianni Paolo play meathead Chaz in Ma.

Dante Brown plays Darrell, a member of Maggie's new friend group. Previously, he's popped up in the Lethal Weapon TV series and the sitcom Mr. Robinson.

The dashing Beauty and the Beast alum plays Andy's father, who shares a deeply unpleasant history with Sue Ann.

We don't want to say too much about Tanyell Waivers's role in the horror film, since that would be a bit of a spoiler. But we can tell you that this isn't the first time she's lit up the screen; she's appeared in Queen Sugar, Bayou Caviar, and Gothic Harvest.

Missi Pyle gets to have a little fun as the ditzy, drunken Mercedes, who's dating Ben.

How the movie studio got Oscar-winner Allison Janney to cameo as Ma's foul-mouthed vet, I'll never know.
