56 Days Cast 2026: Complete Guide to Dove Cameron, Avan Jogia, and the Prime Video Thriller

The steamy new psychological thriller "56 Days" has finally arrived on Prime Video, bringing Catherine Ryan Howard's bestselling novel to the screen with a star-studded cast led by Dove Cameron and Avan Jogia. Here's everything you need to know about the cast, characters, and creative team behind 2026's most addictive erotic thriller.

The series, produced by horror maestro James Wan's Atomic Monster alongside Amazon MGM Studios, has quickly become one of the most talked-about new shows of the year .

What Is '56 Days' About?

Before diving into the cast, here's the gripping premise: The series follows Oliver (Avan Jogia) and Ciara (Dove Cameron), two strangers who meet randomly in a Boston supermarket and fall for each other fast—and dangerously hard. Fifty-six days later, homicide investigators arrive at Oliver's apartment to find an unidentified body—brutally murdered and intentionally decomposed. The central question drives the entire series: Did he kill her? Did she kill him?

The narrative cleverly intercuts between an intense single day in the present investigation and the twisted trajectory of the young lovers' affair in the past, creating a unique crime story that's also a riveting, sexy psychological thriller .

Main Cast of '56 Days' (2026)

Dove Cameron as Ciara Wyse

Dove Cameron leads the cast as Ciara Wyse, a woman whose chance encounter with Oliver spirals into an all-consuming romance—with deadly consequences. Cameron describes the characters as "two deeply lonely people who are not just attracted to each other, but trauma-bonded. Their romance is a chemical reaction fueled by obsession and the hope of being understood" .

Cameron is no stranger to the spotlight. She first rose to fame in dual roles across four seasons of Disney Channel's "Liv and Maddie" and starred as Mal, daughter of Maleficent, in the massively successful "Descendants" film franchise . More recently, audiences have seen her in Apple TV+'s hit musical series "Schmigadoon!" and Mel Brooks' "History of the World Part II" . On stage, she has demonstrated her versatility, starring as Cher in the Off-Broadway production of "Clueless: The Musical" and appearing alongside Renée Fleming in a 2019 London production of "The Light in the Piazza" .

Avan Jogia as Oliver Kennedy

Avan Jogia portrays Oliver Kennedy, the wealthy architect with a mysterious past whose luxurious corporate apartment becomes the series' central crime scene. Jogia acknowledges the importance of chemistry in making the toxic romance believable: "We're very lucky that when we both sat down to do this, the chemistry was just there. I think that's not something that you can practice or improve upon" .

Jogia first captured audiences' attention as Beck Oliver in four seasons of Nickelodeon's "Victorious" . He's since built an impressive resume across film and television, including roles in "Zombieland: Double Tap," "Resident Evil: Welcome to Raccoon City," and the series "Orphan Black: Echoes" .

Karla Souza as Detective Lee Reardon

Karla Souza plays Detective Lee Reardon, one of the two homicide investigators tasked with unraveling what really happened inside Oliver's apartment. Souza brings gravitas to the role, anchoring the present-day investigation with a gripping performance .

Souza is best known for her starring role as Laurel Castillo, one of the "Keating 5," in ABC's hit legal thriller "How to Get Away with Murder" alongside Viola Davis . Reflecting on the similarities between the two projects, Souza noted, "I hadn't really done the link, and then obviously as I was filming it, I was like, 'Oh, who's in the bathtub?' and then all these things now with promoting and I'm like, 'Oh my gosh, it's so similar.' I don't know why I attract this kind of material" .

Dorian Missick as Detective Karl Connolly

Dorian Missick rounds out the lead cast as Detective Karl Connolly, Lee's partner in the investigation. Missick's character provides both procedural expertise and a grounded perspective on the increasingly bizarre case .

Missick's extensive credits include roles in "Luke Cage," "The Burial" opposite Jamie Foxx, "Shirley," and the Oscar-nominated "Sound of Metal" .

Who Is Behind the Camera? Creative Team and Producers

56 Days boasts an impressive creative team and producing lineup that signals its prestige thriller ambitions .

Lisa Zwerling and Karyn Usher serve as creators, writers, and executive producers. The pair, previously behind the Starz drama "The Rook," were drawn to the source material's unique structure. "We got to be great friends with author Catherine Ryan Howard whose book gave us a sexy, emotional, thrill-ride of a show where everything pays off in the end," they said .

James Wan executive produces through his Atomic Monster banner, alongside fellow Atomic Monster executives Michael Clear and Rob Hackett. Wan's horror pedigree—responsible for franchises like "The Conjuring," "Insidious," and the "Saw" series—lends the show its darker, more unsettling moments .

How Has the Show Been Received?

The review praised the chemistry between Cameron and Jogia but suggested the series lacks the heat necessary for a truly memorable erotic thriller .

Pune Mirror offered a more favorable assessment, calling it a "solidly atmospheric, character-driven thriller: not flawless, but tense, twisty and bingeable enough to keep viewers guessing right up to its unsettling final reveal" .

As of late February 2026, the series holds a 6.1/10 rating on IMDb and a 62 percent approval score on Rotten Tomatoes .
