Brittany Snow (Pitch Perfect, Hairspray, X) has been cast as Mandy Matney in Hulu’s Murdaugh Murders limited series.

Matney is the Lowcountry journalist whose podcast, Murdaugh Murders Podcast, and book, Blood on Their Hands: Murder, Corruption and the Fall of the Murdaugh Dynasty, are the basis for the Hulu series.

Snow joins previously announced Jason Clarke as Alex Murdaugh, Patricia Arquette as Maggie Murdaugh, J. Smith-Cameron as Marian Proctor, Johnny Berchtold as Paul Murdaugh, and Will Harrison as Buster Murdaugh. 

The series’ showrunner is Michael D. Fuller, who co-created the project with Erin Lee Carr.

Deadline describes Matney as “a journalist with a sunny smile and a suspicious view of the world. When Mandy starts searching for a story with teeth, she stumbles upon the news of a girl missing as a result of a boat crash. Mandy uses her keen instinct to unravel the complicated layers of the Murdaugh family and ensure that the guilty party is brought to justice.”
